The leg press machine is a piece of gym equipment designed to strengthen the lower body, particularly the quadriceps, hamstrings, and glutes. Users sit in a reclined position and push a weighted platform away using their feet. This exercise mimics the motion of squatting but provides more support for the back. Leg press machines come in various designs, including horizontal and angled versions. They allow for adjustable weights, making it suitable for beginners and advanced lifters alike. Proper form is essential to prevent injury, and users should ensure their knees do not extend beyond their toes during the movement.
