Embodiment Construction

[0042] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0043] The traditional leg hook training is that the trainer lies on the mat, chooses different selection pieces as resistance, and trains the hamstring muscles of the legs through leg hook movements. However, this resistance varies with the exerciser's movement. For example, when doing concentric exercise, the hamstring muscles contract, and the resistance is often reduced due to the influence of the inertia of the selection piece itself. This variation can cause impact injury to the hamstrings while training. At the same time, during the exercise, the point of maximum force exerted by resistance is not synchronized with the point of maximum force exerted by muscles, and the training effect is not ideal....

Abstract

The invention relates to a leg curl training device. The leg curl training device comprises a main frame, a connecting rod structure, a foot curling frame, a pneumatic box and a gas storage tank. Theconnecting rod structure comprises multiple connecting rods which are rotationally connected, the first end of the first connecting rod in the multiple connecting rods is rotationally fixed to the bottom of the main frame, and any point, except the two endpoints, of the last connecting rod in the multiple connecting rods is rotationally fixed to the rear end of the main frame; the foot curling frame is connected with one end of the last connecting rod; the pneumatic box is provided with an air cylinder, the air cylinder comprises a piston and a piston rod, the air cylinder is fixed in the manner of being capable of rotating by a certain angle in the plane of the length direction of the air cylinder, one end of the piston rod is connected with the piston, and the other end of the piston rodis rotationally coupled to any point, except the first end, of the first connecting rod. The gas storage tank is used for storing compressed gas and connected with the air cylinder to supply compressed gas to the air cylinder.

Description

technical field [0001] The present invention generally relates to the field of fitness equipment, in particular to a leg hook trainer. Background technique [0002] With the popularization of health knowledge and the improvement of people's living standards, people pay more and more attention to their own health. As a green way to maintain health and shape body, fitness is increasingly favored by the public. Leg hooks are a common fitness exercise performed to train the hamstrings. Conventional leg hook training equipment generally changes resistance simply by changing or adding bell plates or selector plates. However, the resistance of these machines changes as the exerciser moves. For example, when doing concentric movements (when the hamstrings contract), the resistance is often reduced due to the inertia of the selection plate itself. And at the same time, during the exercise, the point of maximum force exerted by resistance is not synchronized with the point of maxi...
