Leg training device for athletes in track and field

Abstract

The invention relates to the technical field of leg training devices, and discloses a leg training device for athletes in track and field, the leg training device comprises an equipment body, and support legs are fixedly mounted on the left and right sides of the bottom of the equipment body. According to the leg training device for athletes in track and field, a tightening bolt is arranged on thelimiting seat; when the weight of the counterweight box needs to be adjusted; firstly, the tightening bolt is screwed off and the rotating rod is rotated in the opposite direction, and the cover plate can be opened, the counterweight blocks in the counterweight box are increased or decreased; by adjusting the weight of the counterweight, the cover plate is covered and the tightening bolt is locked; an athlete only needs to sit on the cushion, the two feet step on the pedal plates, the pedal plates are pedaled forcefully, the movable sleeve rods drive the pedal plates and the whole counterweight box to slide up and down in the direction of the connecting rods, high-strength training can be conducted on the leg strength of an athlete, the leg strength of the athlete can be effectively trained, and the practicability of the leg strength training device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of leg training devices, in particular to a leg training device for track and field athletes.
