[0017] The beneficial effects of this invention are as follows: 1. The exercise bike with a multi-point support adjustable base described in this invention facilitates ankle relaxation for the exerciser through the designed support plate, preventing sprains caused by failure to relax the ankle after high-intensity training. When relaxing the exerciser's ankle, the exerciser's foot is placed on the support plate, and the drive shaft rotates in both directions via a gear. The rotation of the drive shaft causes the support plate to rotate in both directions, which in turn causes the exerciser's foot to move from side to side, thereby relaxing the exerciser's ankle, relieving muscle fatigue, directly stretching muscle groups, quickly reducing soreness, and the slow twisting can relax the ligaments and tendons around the joint, preventing stiffness, maintaining flexible power generation during pedaling, and accelerating blood circulation in the ankle and lower leg, helping to metabolize lactic acid produced after exercise and reducing delayed onset muscle soreness.

[0018] 2. The exercise bike with a multi-point support adjustable base described in this invention facilitates massage and relaxation of the calves of the user through the specially designed shaped plates and silicone heads. This effectively avoids muscle strain caused by not relaxing muscles in time after high-intensity training. The massage mechanism massages the calves of the user during exercise, directly relaxing stiff muscle groups, reducing soreness, preventing muscle lumps, promoting local blood circulation, helping to eliminate metabolic waste, reducing delayed onset muscle soreness, facilitating relaxation of the user, ensuring improved recovery efficiency, preventing injury, and enabling long-term exercise.

[0019] 3. The exercise bike with a multi-point support adjustable base frame described in this invention facilitates heating, massage, and relaxation treatment through the provided cavity and water tank. When the water pump operates, it draws water from the water tank, and the drawn water flows into the cavity through the water inlet. The temperature carried by the water is transferred to the silicone head, causing the silicone head to heat up. This further dilates blood vessels, promotes metabolism, and relieves muscle fatigue and delayed onset muscle soreness when massaging the user's legs.

[0020] 4. The exercise bike with a multi-point support adjustable base frame described in this invention facilitates resource recovery through the setting of friction blocks and sliding grooves. When the push plate moves repeatedly, the push rod will drive the friction blocks to slide inside the sliding grooves. The friction blocks can generate heat through repeated movement inside the sliding grooves, and the heat will be transferred to the water source inside the water tank to heat the water source inside the water tank, thereby achieving the purpose of energy recovery and reducing resource waste.

[0021] 5. The exercise bike with a multi-point support adjustable base frame described in this invention moves the sliding plate, which in turn drives the second support block to move synchronously. After the sliding plate moves to a predetermined position, the limiting bolt is rotated to position the sliding plate. At the same time, the adjusting bolt is rotated to adjust the position of the second support block. After the second support block contacts the ground, it can support and limit the exercise bike with a multi-point support adjustable base frame, achieving the purpose of multi-point support and ensuring stability.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0026] like Figures 1 to 17As shown in the embodiment of the present invention, an exercise bike with a multi-point support adjustable base includes a base plate 1, a support mechanism at the bottom of the base plate 1, a shell 2 fixedly mounted on the base plate 1, a resistance mechanism for exercise inside the shell 2, a handrail 3 mounted on the base plate 1, a controller 4 fixedly mounted on the handrail 3, a support frame 55 fixedly mounted on the top of the base plate 1, a power mechanism inside the support frame 55, symmetrically arranged annular grooves 65 inside the support frame 55, and a guide groove 66 inside the support frame 55, the guide groove 66 being aligned with the annular groove 65. The annular grooves 65 are connected. A drive shaft 69 is rotatably installed inside the annular groove 65. A gear 70 is fixedly installed on the drive shaft 69. A guide ring 68 is rotatably installed inside the guide groove 66. A support plate 67 is fixedly installed inside the guide ring 68. A square block 56 is fixedly installed on the top of the support frame 55. An arc plate 57 is symmetrically arranged inside the square block 56 and is located directly above the corresponding annular groove 65. A water storage mechanism is installed inside the square block 56. A massage mechanism for massaging and relaxing the calves is installed inside the arc plate 57. Both the battery 38 and the controller 4 are electrically connected to the electronic equipment on the exercise bike with a multi-point support adjustable base. The electronic equipment can be controlled to work through the cooperation of the controller 4 and the battery 38 (prior art). When exercising on an exercise bike with a multi-point support adjustable base, the base plate 1 is fixedly supported by the support mechanism. The user sits on the support seat 31, places their feet on the foot pedals 9, and rests their hands on the handrails 3. The resistance mechanism allows for adjustable resistance, facilitating exercise. The base plate 1 is a square block 56 to increase installation space. After prolonged exercise, when the user needs to relax their ankles and calves, their posture is adjusted so that their feet are placed on the support plate 67. The top of the support plate 67 has an array of recesses to ensure sufficient friction between the foot and the top of the support plate 67. Controlling the power mechanism causes the first rack 64 to move repeatedly. The reciprocating motion of the first rack 64 drives the drive shaft 69 to rotate in both directions via the first gear 70. The rotation of the drive shaft 69, in turn, drives the support plate 67 to rotate in both directions. This rotation is achieved through the cooperation of the guide ring 68 and the guide groove 66. This will allow the support plate 67 to move smoothly. When the support plate 67 moves forward and backward, it will drive the trainee's feet to move left and right, thereby relaxing the trainee's ankles, relieving muscle fatigue, directly stretching muscle groups, and quickly reducing soreness. The slow twisting can relax the ligaments and tendons around the joints, prevent stiffness, maintain flexible power during pedaling, and accelerate blood circulation in the ankles and calves, helping to metabolize lactic acid produced after exercise and reduce delayed onset muscle soreness. In addition, the movement of the power mechanism will drive the movement of the massage mechanism. The calves are located inside the arc plate 57, and the movement of the massage mechanism will massage the trainee's calves. The massage can directly relax stiff muscle groups, reduce soreness, prevent muscle knots, promote local blood circulation, help eliminate metabolic waste, reduce delayed onset muscle soreness, facilitate relaxation treatment for the trainee, ensure improved recovery efficiency, prevent injury, and maintain long-term exercise.

[0027] Furthermore, the resistance mechanism includes a motion disc 5, a rotating shaft 8, a foot pedal 9, a connecting component, and an adjusting component. The motion disc 5 is rotatably disposed inside the housing 2, the rotating shaft 8 is rotatably disposed inside the housing 2, the foot pedal 9 is disposed on the rotating shaft 8, the connecting component is disposed on the rotating shaft 8, and the adjusting component for adjusting the resistance of the motion disc 5 is disposed on the housing 2. The adjustment assembly includes an adjustment screw 6 and a limiting block 7. The adjustment screw 6 is threadedly connected to the housing 2, and the top of the limiting block 7 is fixedly connected to the bottom of the adjustment screw 6. The limiting block 7 is located directly above the moving disc 5. The connecting assembly includes a drive wheel 10, a groove 11, a slide 12, a positioning block 13, a housing 14, a first dual-output shaft motor 15, a threaded rod 16, a threaded cylinder 17, and an adjusting plate 18. The drive wheels 10 are symmetrically arranged on the rotating shaft 8. The grooves 11 are arranged in a ring array inside the drive wheels 10. The slide 12 corresponding to the grooves 11 are symmetrically arranged inside the rotating shaft 8. The positioning block 13 passes through the slide 12. The housing 14 corresponding to the slide 12 is embedded inside the rotating shaft 8, and the slide 12 and the housing 14 are connected. The first dual-output shaft motor 15 is fixedly mounted on the housing 14. Inside the housing 14, the threaded rod 16 is rotatably mounted inside the housing 14, and the end of the threaded rod 16 is fixedly connected to the output end of the first dual-shaft motor 15. The threaded rod 16 is threadedly connected to the threaded cylinder 17, and the threads on the two threaded rods 16 are opposite. The end of the threaded cylinder 17 is fixedly mounted with an adjusting plate 18. The side of the moving disc 5 is fixedly mounted with a first driven wheel 19, and the first driven wheel 19 is connected to one of the drive wheels 10 through belt drive. The housing 14 is fixedly mounted with a guide shaft 20, and the guide shaft 20 passes through the adjusting plate 18. The housing 14 is fixedly mounted with a power supply assembly 21. After the trainee sits on the support seat 31, places their feet on the foot pedals 9, and places their hands on the armrests 3 for limb support, the leg movement can drive the rotating shaft 8 to rotate. When the rotating shaft 8 rotates, it will drive the corresponding drive wheel 10 to rotate through the cooperation of the connecting component and the adjustment component. When the drive wheel 10 rotates, it will drive the exercise disc 5 to rotate through the cooperation of the belt and the first driven wheel 19, thus enabling pedaling. Rotating the adjustment screw 6 will adjust the position of the adjustment screw 6, which will drive the limit block 7 to move synchronously. The limit block 7 moves down to contact the top of the exercise disc 5, which can adjust the resistance and thus adjust the intensity for training. The electronic equipment on the exercise bike with a multi-point support adjustable base is powered by the power supply component 21, except for the No. 1 dual-output shaft motor 15. The other electronic equipment is powered by the storage battery 38. The controller 4 is also electrically connected to the No. 1 dual-output shaft motor 15 and can control the No. 1 dual-output shaft motor 15 to work, thereby driving the threaded rod 16 to rotate. The rotation of the threaded rod 16 can adjust the position of the threaded cylinder 17. When the threaded cylinder 17 moves, it will drive the adjusting plate 18 to move, which will in turn drive the positioning block 13 to slide inside the slide groove 12. After the positioning block 13 moves out of the groove 11, the rotating shaft 8 and the drive wheel 10 are no longer fixedly connected. Conversely, after the positioning block 13 enters the groove 11, the rotating shaft 8 and the drive wheel 10 will be temporarily fixedly connected. In this way, it is possible to control whether the two drive wheels 10 rotate with the rotating shaft 8.

[0028] Furthermore, a support plate 22 is provided on the top of the outer shell 2, and a power box 23 is embedded in the top of the support plate 22.

The output end of the first motor 25 is fixedly connected to the input end of the first reducer 24. A connecting shaft 29 is fixedly connected to the output end of the first reducer 24. A load-bearing plate 26 is fixedly installed on the top of the support plate 22, and the connecting shaft 29 passes through the center of the load-bearing plate 26. A groove 27 is provided inside the load-bearing plate 26, and a support ring 28 is rotatably installed inside the groove 27. A disc 30 is fixedly installed on the top of the support ring 28, and the top of the connecting shaft 29 is fixedly connected to the center of the disc 30. A support seat 31 is fixedly installed on the top of the disc 30. The support plate 22 is telescopically adjustable in height (existing technology). It supports the trainee through the support seat 31. Controlling the operation of the first motor 25 will drive the first reducer 24 to move. When the first reducer 24 moves, it will drive the disc 30 to rotate. When the disc 30 rotates, it will drive the support ring 28 to rotate inside the groove 27, which will guide the disc 30 to rotate smoothly. When the disc 30 rotates, it will adjust the angle of the support seat 31, thereby adjusting the trainee's sitting posture.

[0029] Furthermore, the support mechanism includes a strip frame 32, a first support block 33, a limiting bolt 34, a sliding plate 35, an adjusting bolt 36, and a second support block 37. The strip frame 32 is symmetrically arranged at the bottom of the base plate 1, the first support block 33 is symmetrically arranged at the bottom of the strip frame 32, the limiting bolt 34 is threadedly connected to the strip frame 32, the sliding plate 35 is symmetrically arranged inside the strip frame 32, the adjusting bolt 36 is threadedly connected to the inside of the sliding plate 35, the second support block 37 is fixedly arranged at the bottom end of the adjusting bolt 36, and a storage battery 38 is fixedly arranged at the top of the base plate 1. The bar frame 32 is supported by the first support block 33, which in turn supports the exercise bike with a multi-point support adjustable base. The support position can be adjusted according to the usage scenario. Moving the sliding plate 35 will cause the second support block 37 to move synchronously. After the sliding plate 35 moves to the predetermined position, the limit bolt 34 is rotated to position the sliding plate 35. At the same time, rotating the adjustment bolt 36 will adjust the position of the second support block 37. After the second support block 37 contacts the ground, it can support and limit the exercise bike with a multi-point support adjustable base, achieving the purpose of multi-point support and ensuring stability.

[0030] Furthermore, a protective cover 39 is provided on the side of the outer shell 2. A first rotating shaft 40 is rotatably provided inside the protective cover 39. A second driven wheel 41 is fixedly provided on the first rotating shaft 40, and the second driven wheel 41 is connected to the corresponding drive wheel 10 through belt drive. A rotating disk 42 is fixedly provided at the end of the first rotating shaft 40. A connecting plate 43 is movably connected to the rotating disk 42. A square groove 44 is fixedly provided inside the protective cover 39. A push plate 45 passes through the square groove 44, and one end of the push plate 45 is movably connected to the connecting plate 43. The water storage mechanism includes a water tank 51, a temperature sensor 52, and an injection pipe 53. The water tank 51 is fixedly installed inside the square block 56 and is located between two arc-shaped plates 57. The temperature sensor 52 is installed inside the water tank 51. The injection pipe 53 is fixedly installed on the top of the water tank 51. An observation window 54 is provided on the side of the water tank 51. The outer shell 2 provides installation space for the protective cover 39, and the protective cover 39 provides installation space for the first rotating shaft 40. During normal training, the rotation of the rotating shaft 8 will not drive the drive wheel 10 corresponding to the second driven wheel 41 to rotate. When it is necessary to drive the rotating disk 42 to move, the corresponding drive wheel 10 is temporarily fixedly connected to the rotating shaft 8. The second driven wheel 41 will drive the first rotating shaft 40 to rotate, which in turn will drive the rotating disk 42 to rotate. The rotation of the rotating disk 42, in cooperation with the connecting plate 43, will drive the push plate 45 to move repeatedly inside the square groove 44. The movement resistance can also be adjusted. If the driving resistance is too high during movement, the drive wheel 10 corresponding to the first driven wheel 19 can be controlled to no longer be fixedly connected to the rotating shaft 8. Thus, when the rotating shaft 8 rotates, it will not drive the moving disk 5 to move, but only drive the push plate 45 to move. It can be adjusted according to needs. Water can be added to the water storage tank 51 through the injection pipe 53. The water temperature inside the water storage tank 51 can be monitored through the temperature sensor 52. The monitored data is displayed on the display screen on the controller 4 (existing technology) to facilitate personnel control. A pipe is provided on the side of the water storage tank 51, and a valve is provided on the pipe to discharge the water inside the water storage tank 51.

[0031] Furthermore, a partition plate 46 is fixedly installed inside the water storage tank 51, and one end of the push plate 45 extends into the water storage tank 51. A sliding groove 47 is arranged in an array inside the water storage tank 51, and the sliding groove 47 is located on one side of the partition plate 46. A friction block 48 is engaged inside the sliding groove 47. A push rod 49 is fixedly connected to one side of the friction block 48, and the other end of the push rod 49 is fixedly connected to the push plate 45. An electric heating rod 50 is installed at the top of the sliding groove 47. The partition plate 46, in conjunction with the sliding groove 47, divides the area below the water storage tank 51, preventing the water inside the tank from flowing to the location of the push plate 45. As the push plate 45 moves repeatedly, the push rod 49 drives the friction block 48 to slide inside the sliding groove 47. The friction block 48 generates heat through repeated movement within the groove, which is then transferred to the water inside the tank 51 to heat it, thus achieving energy recovery and reducing resource waste. The temperature sensor 52 monitors the water temperature inside the tank 51. If the water temperature inside the tank 51 is insufficient, the electric heating rod 50 can be activated to generate heat and heat the water inside the tank 51.

[0032] Furthermore, the power mechanism includes a drive housing 58, a second dual-output shaft motor 59, a second reducer 60, a crankshaft 61, a transmission plate 62, and a drive wheel 71. The drive housing 58 is fixedly installed inside the support frame 55 and is located on one side of the annular groove 65.

The drive box 58 is internally symmetrically provided with a connecting groove 63 corresponding to the transmission plate 62. The connecting groove 63 is connected to the annular groove 65. A rack 64 passes through the connecting groove 63. The rack 64 meshes with the corresponding gear 70. The other end of the transmission plate 62 is movably connected to the end of the rack 64. The movement of the No. 2 dual-output shaft motor 59 will drive the No. 2 reducer 60 and the water pump 89 respectively. When the No. 2 reducer 60 moves, it will drive the crankshaft 61 to move. The movement of the crankshaft 61 will drive the transmission plate 62 to move, and at the same time drive the power wheel 71 to rotate. When the transmission plate 62 moves, it will drive the No. 1 rack 64 to move repeatedly. The No. 1 rack 64 will be guided through the connecting groove 63 to make the No. 1 rack 64 move smoothly. When the No. 1 rack 64 moves, it will drive the drive shaft 69 to rotate through the No. 1 gear 70.

[0033] Furthermore, a water pump 89 is fixedly installed inside the drive box 58, and the other output end of the No. 2 dual-output shaft motor 59 is fixedly connected to the impeller inside the water pump 89 through a shaft, and the input end of the water pump 89 is connected to the inside of the water storage tank 51 through a pipe. When the water pump 89 moves, it draws water from the water storage tank 51. The water drawn by the water pump 89 is then transported to the cavity 85 through the inlet head 87.

[0034] Furthermore, a frame 72 is fixedly installed on the top of the support frame 55, and a third reducer 73 is fixedly installed inside the frame 72. The input end of the third reducer 73 is fixedly connected to a third driven wheel 74, and the third driven wheel 74 is connected to the power wheel 71 via belt drive. A disc 75 is fixedly connected to the output end of the third reducer 73, and a shaft 76 is fixedly installed on the disc 75. A slat 77 is movably connected to the shaft 76. A limit groove 78 is provided at the end of the frame 72, and a second rack 79 passes through the limit groove 78. The end of the second rack 79 is movably connected to the other end of the slat 77. When the drive wheel 71 rotates, it drives the third driven wheel 74 to rotate, which in turn drives the third reducer 73 to move. The movement of the third reducer 73 drives the disc 75 to rotate. When the disc 75 rotates, it drives the second rack 79 to move repeatedly inside the limit groove 78 through the cooperation of the shaft 76 and the plate 77. When the second rack 79 moves, it drives the corresponding second gear 83 to rotate in both directions.

[0035] Furthermore, the massage mechanism includes a movable frame 80, a support rod 81, a shaped plate 82, a second gear 83, and a silicone head 84. The movable frame 80 is located inside the square block 56 and is connected to the interior of the arc-shaped plate 57. The support rod 81 is symmetrically rotated and located inside the movable frame 80. The shaped plate 82 is fixedly arrayed on the support rod 81, with one end of the shaped plate 82 extending into the interior of the arc-shaped plate 57. The second gear 83 is fixedly mounted on the support rod 81, and two second gears 83 mesh with each other. The second rack 79 is connected to it. A second gear 83 meshes with the silicone head 84, which is fixedly installed at one end of the irregular plate 82. The irregular plate 82 has a cavity 85 inside, and the cavity 85 is located on one side of the silicone head 84. A connecting pipe 86 is provided on the irregular plate 82, and adjacent cavities 85 are connected through the connecting pipe 86. One of the cavities 85 is connected to a water inlet head 87, and the water inlet head 87 is connected to the output end of the water pump 89 through a hose. The lowest cavity 85 is connected to a drain head 88, and the drain head 88 is connected to the inside of the water storage tank 51 through a hose. When one of the gears 83 rotates in both directions, it drives the other gear 83 to move in the opposite direction. The movement of gear 83 drives the support rod 81 to rotate, which in turn drives the shaped plate 82 to move. The movement of the shaped plate 82 drives the silicone head 84 to move, and the silicone head 84 massages the calf muscles. After training, this massage can relax the calves and prevent muscle strain. When the water pump 89 operates, it draws water from the water tank 51. The drawn water flows into the cavity 85 through the inlet head 87. The temperature of the water is transferred to the silicone head 84, raising its temperature. This further dilates blood vessels, promotes metabolism, and relieves muscle fatigue and delayed onset muscle soreness. Through the connecting pipe 86 and the drain head 88, the water flows back into the water tank 51 for storage. The temperature sensor 52 monitors the water temperature inside the water tank 51 to prevent the water from overheating.

[0036] Working Principle: First, when exercising on an exercise bike with a multi-point support adjustable base, moving the sliding plate 35 will cause the second support block 37 to move synchronously. After the sliding plate 35 moves to the predetermined position, rotating the limit bolt 34 will position the sliding plate 35. At the same time, rotating the adjustment bolt 36 will adjust the position of the second support block 37. After the second support block 37 contacts the ground, it can provide support and limit the exercise bike with a multi-point support adjustable base, achieving the purpose of multi-point support and ensuring stability. After the trainee sits on the support seat 31, steps on the foot pedal 9, and places their hands on the handrail 3, the leg movement will drive the rotating shaft 8 to rotate. When the rotating shaft 8 rotates, it will drive the corresponding... The drive wheel 10 rotates, and when it rotates, it drives the motion disc 5 to rotate via a belt and the first driven wheel 19, thus enabling pedaling motion. Rotating the adjusting screw 6 adjusts its position, which in turn moves the limit block 7 synchronously. The limit block 7 moves down to contact the top of the motion disc 5, adjusting the resistance and thus the training intensity. The base plate 1 is a square block 56 to increase installation space. During normal training, the rotation of the rotating shaft 8 does not drive the drive wheel 10 corresponding to the second driven wheel 41. When it is necessary to move the motion disc 42, the corresponding drive wheel 10 is temporarily fixed to the rotating shaft 8. The second driven wheel 41 then drives the first rotating shaft 40 to rotate, which in turn drives the motion disc 42 to rotate. The rotation, through the connecting plate 43, causes the push plate 45 to move repeatedly within the square groove 44. The resistance can also be adjusted. If the driving resistance is too high during movement, the drive wheel 10 corresponding to the first driven wheel 19 can be decoupled from the rotating shaft 8. Thus, when the rotating shaft 8 rotates, it will not drive the moving disc 5, but only the push plate 45. This can be adjusted as needed. During the repeated movement of the push plate 45, the push rod 49 causes the friction block 48 to slide within the sliding groove 47. The repeated movement of the friction block 48 within the sliding groove 47 generates heat through friction, which is then transferred to the water source inside the water tank 51, heating the water and achieving energy recovery, reducing resource waste, and allowing for longer training sessions. After exercise, when it's time to relax the trainee's ankles and calves, the first motor 25 drives the first reducer 24. The reducer 24 rotates the disc 30, which in turn rotates the support ring 28 within the groove 27, guiding the disc 30 to rotate smoothly. The rotation of the disc 30 adjusts the angle of the support seat 31, allowing the trainee to adjust their sitting posture. The trainee's feet rest on the support plate 67, whose top is equipped with recessed blocks to ensure sufficient friction between the foot and the top of the plate. Controlling the second dual-shaft motor 59 drives the second reducer 60 and the water pump 89. The movement of the second reducer 60 drives the crankshaft 61.The movement of crankshaft 61 drives the transmission plate 62 to move, which in turn drives the drive wheel 71 to rotate. The movement of transmission plate 62 drives rack 64 to move repeatedly. The connecting groove 63 guides rack 64, ensuring its smooth movement. The movement of rack 64, via gear 70, drives drive shaft 69 to rotate in both directions. The rotation of drive shaft 69 drives support disc 67 to rotate in both directions. The guide ring 68 and guide groove 66 work together to ensure smooth movement of support disc 67. The rotation of support disc 67 in both directions drives… The trainee's left and right foot movements relax the ankles, relieving muscle fatigue, directly stretching muscle groups, and quickly reducing soreness. Slow twisting relaxes the ligaments and tendons around the joints, preventing stiffness, maintaining flexibility and power during pedaling, and accelerating blood circulation in the ankles and lower legs. This helps metabolize lactic acid produced after exercise, reducing delayed onset muscle soreness. Furthermore, the movement of the power mechanism drives the massage mechanism; the lower leg is located inside the curved plate 57, and the rotation of the power wheel 71 drives the third driven wheel 74, which in turn drives the third... When reducer 73 moves, it drives disc 75 to rotate. The rotation of disc 75, through the cooperation of shaft 76 and slat 77, pushes rack 79 to move repeatedly within the limiting groove 78. The movement of rack 79 drives corresponding gear 83 to rotate in both directions. When one gear 83 rotates in both directions, it drives the other gear 83 to move in the opposite direction. The movement of gear 83 then drives support rod 81 to rotate, which in turn drives the irregular plate 82 to move. The movement of plate 82 moves the silicone head 84, which massages the calves after training, helping to relax and prevent muscle strain. Simultaneously, the water pump 89 draws water from the storage tank 51, which flows into the cavity 85 through the inlet head 87. The heat from the water is transferred to the silicone head 84, raising its temperature and further dilating blood vessels, promoting metabolism, and relieving muscle fatigue and delayed onset muscle soreness.
