Abstract
An exercise device for performing exercises suitable to strengthen thigh and hip muscles such as a leg press machine, a total hip, a stationary bicycle, or a moving bicycle, and more particularly provides an exercise device for strengthening thigh and hip muscles while protecting the knees and ankle joints by enabling a user to locate a lower end of an arm on the user's thighs in a sitting, prone or supine position and move the user's legs in order to minimize a load or stress added to the knee and ankle joints.
Claims4
An exercise device for exercising upper leg portions and hips while protecting knee and ankle joints, the exercise device comprising:
- a frame having a ground strut and a front handlebar to be held by the user for postural stability;
- a seat connected to the frame and configured to support a user in a sitting position;
- an arm pivotably connected to the frame adjacent the seat and rotatable about an axis at a first end of said arm, said arm having an elastic body holder at a second end of said arm;
- a pad pivotably connected to the first end of the arm and configured to contact the user's leg and rotate about the said axis during use;
- and an elastic body connected between said ground strut and said elastic body holder of said arm;
- said elastic body providing a resistive force against pivoting of the arm that rotates when the thigh pad moves;
- wherein the exercise device is configured to allow the user to sit on the seat, in a sitting position with the user's leg on the pad, and move the thigh of the user backward from an exercise starting position where the thigh is pulled toward the user's chest such that the user's thigh moves during exercises and the user flexes a hip while exercising.
