Reverse arch type waist and abdomen strength training device

Abstract

The invention discloses a reverse arch type waist and abdomen strength training device, which comprises a lower limb limiting mechanism and a trunk supporting mechanism, the lower limb limiting mechanism comprises a foot limiting rod, a knee limiting rod, a first connecting rod and lower limb adjusting plates, and the knee limiting rod, the first connecting rod and the foot limiting rod are assembled into an I-shaped structure; the two radial sides of the first connecting rod are each provided with a lower limb adjusting plate, the first connecting rod and the lower limb adjusting plates are connected through a first rotating shaft and a lower limb adjusting pin, the two lower limb adjusting plates are coaxially assembled, and the axial direction of the two lower limb adjusting plates is parallel to the axial direction of the knee limiting rod; the lower limb adjusting plates are connected with a supporting component through a supporting connecting piece, and the upper end of the supporting connecting piece is connected with the trunk supporting mechanism. By adjusting the included angle between the thigh and the shank, the tension load of the thigh muscle group is reduced, slight strain of the thigh muscle during waist and abdomen strength training is avoided, and people can conduct appropriate healthy and scientific progressive strength training.

Description

technical field [0001] The invention relates to the technical field of fitness equipment. Specifically, it is an anti-bow type waist and abdomen strength training device. Background technique [0002] In daily life, because there are few occasions to use waist and abdomen strength and the time is short, it is easy for people to ignore the exercise of waist and abdomen strength. But when doing physical activity for a long time, some people tend to feel tired easily, especially feeling that the trunk strength (mainly waist and abdomen strength) is insufficient, which makes some people like to slump on the sofa or chair after long-term physical activity. However, some existing waist and abdomen strength training exercises are not effective, such as sit-ups, especially in the advanced training process of waist and abdomen strength. Sit-ups can only meet the initial enhancement of waist and abdomen strength, but cannot further improve Abdominal strength. When using equipment t...

However, when doing physical activity for a long time, some people tend to feel tired easily, especially the lack of trunk strength (mainly waist and abdomen strength), which makes some people like to sit on the sofa or chair after long-term physical activity

However, some existing waist and abdomen strength training exercises are not effective, such as sit-ups, especially in the advanced training process of waist and abdomen strength. Sit-ups can only meet the initial enhancement of waist and abdomen strength, but cannot further improve Abdominal strength

When using equipment to exercise waist and abdomen strength, the existing equipment has poor universality. For example, people with poor leg muscle group flexibility are not suitable for using the existing abdominal muscle board for exercise. The reason is that using the existing abdominal muscle board During the muscle board exercise, the tension load of the thigh muscle group is relatively large, and it is easy to cause slight strain of the thigh muscle group when exercising the strength of the waist and abdomen
