Description

Self-weight type inclined upward pedal trainer

Technical Field

The invention relates to the field of fitness equipment, in particular to a self-weight type inclined upward pedaling trainer.

Background

At present, with the improvement of living standard of people, more and more people start to build body, fitness equipment also starts to be popularized more and more, and the training mode is more and more exquisite. Wherein the oblique kicking-up exercise has good effect on the exercise of quadriceps femoris and gluteus maximus, and the movement track when the user takes exercise is: bending the knees until the knees are close to the chest as much as possible, and then exerting force forwards on the legs to enable the legs to be straightened. Then, the operation is slowly resumed. The exercise mode has the advantages of simple and practical learning, good exercise effect, strong adaptability and the like, thereby being prepared for the preference of body building enthusiasts.

However, the existing back-pedal trainer has one biggest problem in the using process: the force applied to the foot plate is constant throughout the movement of the user, while the knee joint is in a cycle of flexion, extension, and re-flexion throughout the movement. Under the condition that the force applied to the pedal by a user is constant, the position of the knee joint is constantly changed, and the stress of the knee joint is also constantly changed, so that the stress of the knee joint is very large when the user bends and pedals on the knee at the initial position, and the knee joint is very easy to be damaged. And the shank is stretched out completely the back, and the knee joint atress alleviates suddenly, and the user feels the light in weight who pushes away the leg again and has been more or less, though always is the constant force, but user's knee joint when initial power of exerting oneself, the atress is the biggest, if do not preheat earlier stage, can cause the very big pressure of knee, leads to the knee to be injured easily to the training ware commonality is not strong, to the people of different heights size, can not adjust the height at will, can not adjust at will to user's particular case at will.
