The rotating column 2321 is rotationally connected to the fixing column 2312, and the rotating rod 2322 is welded to the rotating column 2321. The rotating rod 2322 can be driven by the training column 234 to move on the rotating column 2321. The sliding component 233 includes a sliding groove 2331 and a connecting piece 2332. The sliding groove 2331 is arranged on the rotating rod 2322. The connecting piece 2332 passes through the sliding groove 2331, and the connecting piece 2332 is bolted to the training column 234. The training column 234 moves back and forth through the sliding of the connecting piece 2332 in the sliding groove 2331, enabling the track and field athlete to smoothly perform leg kicking movements.The weight part 3 includes a weight adjustment box 31, a traction steel wire rope 32, and a touch display screen 33. The bottom of the weight adjustment box 31 is welded to the top of the connecting seat 111. The traction steel wire rope 32 is arranged inside the weight adjustment box 31. The traction steel wire rope 32 connects the lifting assembly 232 and the sliding assembly 233. The traction steel wire rope 32 passes through the fixing assembly 231. The connecting piece 2332 connects the outer end of the traction steel wire rope 32. The lifting assembly 232 and the sliding assembly 233 are connected inside the weight adjustment box 31 through the traction rope. The traction weight is adjusted by the weight adjustment box 31, and then an appropriate weight is adjusted for leg press training or leg flexion and extension training. The touch display screen 33 is embedded in the front of the weight adjustment box 31. The mode is adjusted through the touch display screen 33, and the leg press training mode and the leg flexion and extension mode are replaced. The combined training of the two modes is carried out on a training device, effectively exercising the strength of the entire leg. The weight of the weight adjustment box 31 is adjusted through the touch display screen 33. Track and field athletes can select an appropriate training weight for leg exercise, switch modes with one key, and adjust the weight, height, and angle at will, providing an intelligent and convenient leg exercise experience for track and field athletes.
