King Size Male Enhancement To build strength in your legs, use wall sits. To start, find a clear space of wall that will easily fit the width of your body. Start about a foot and a half away from the wall, with your back towards the wall. Lean back against the wall and bend your knees. Continue bending your knees so that your thighs become parallel to the floor and you find yourself in a crouched position, just off the floor. Hold this position until your muscles give out.
