Front Leg Extension

Lift one to hip height. Extend the leg until your knee is locked. Hold for 2-5 seconds then return. Do not return foot to the ground. Keep the knee up at hip height for entire set. If you cannot fully extend/straighten your knee, lower your leg slightly until you can. As you develop strength you should be able to keep your knee higher and higher. Use a wall or chair if you have trouble balancing.

Tighten and/or squeeze your quadricep when your foot is extended to maximize muscle recruitment.
