The invention discloses a Pilates exercise training bed. The main point of the technical scheme is that by pulling the stretching rope, the stretching rope can be rotated and slide in the horizontal direction at the same time, and then one end of the stretching rope can be fixed on the leg at the same time. Movement in the vertical direction and horizontal direction forms an arc-shaped movement path, which is more in line with the movement state of the legs; during exercise, the stretching rope can be conveniently connected to the driving device to realize the automatic stretching action. The exercise effect can reduce the degree of exertion at the same time. The movement mode of the stretching rope is more in line with the active state of the legs, making the training movements more standard, and avoiding leg muscle strain and knee and hip joint injuries. Avoid the variable movement speed and path of the stretching rope, prevent discomfort or damage caused by stretching the legs, and ensure the effect of movement. The protruding length of the contact end of the stretching rope can be set according to different sports actions, so that the sports are personalized and convenient.
