The leg press is a weight training exercise that targets the muscles of the legs, including the quadriceps, hamstrings, and glutes. It is typically performed using a leg press machine, which consists of a weight stack and a platform to sit or lie on. To perform the exercise, you will need to adjust the machine to fit your body and then sit or lie on the platform with your feet on the footplate. From there, you will need to push against the footplate with your legs to lift the weight stack. Be sure to keep your back and hips pressed against the platform throughout the exercise to maintain good form and avoid injury. It's also important to use a weight that is challenging but manageable and to avoid locking your knees at the top of the movement.
