[0002] The water resistance system can control the resistance according to the amount of water and the speed of the blades or flywheels, helping the exerciser to develop more than 80% of the body's resistance. Therefore, more and more fitness equipment currently uses water resistance systems, such as rowing machines, which are also known as rowing machines, rowing machines, rowing machines, rowing machines, ergometers, land rowing machines, and indoor rowing machines. Fitness equipment is a machine used to simulate water rowing for the purpose of training; the current rowing machines mainly have three resistance modes: wind resistance, magnetic resistance, and water resistance; among them, the water resistance rowing machine has the best simulation technology, which can make people feel the sight, sound, and feeling of real rowing. During exercise, the resistance of the liquid and the change of the wheel speed are used in a short period of time to exercise the body's muscles, especially for the strengthening of the legs, waist, upper limbs, chest, and back muscles. After each complete contraction and extension, the muscles of the whole body can achieve the effect of aerobic exercise.

[0003] At present, there may be the following problems in the water resistance system:

[0004] First, when the water resistance needs to be adjusted, more liquid needs to be added or liquid needs to be pumped out, but this operation is not convenient for quick adjustment;

[0005] Second, although some structures can adjust the water resistance, it is impossible to position it during adjustment.

[0006] In view of this, the inventor specially designed a water resistance regulating device and fitness equipment, and this case was thus generated. Utility Model Content
