Practice the "invisible chair" exercise to strengthen up your legs. First NeuroFuse you need an unobstructed wall that is at least the width of your body. Stand roughly 18 inches facing away from the wall. Bend your knees and lean back until your entire back is touching the wall. You should then bend the knees until the thighs and the ground are parallel and your body is in a seated position. Stay in this position for as long as you can maintain it.
