Here is a great way to enhance your leg workouts. The supine bridge with one leg is an advanced version of the standard supine bridge. This version of the bridge will require an intermediate level of fitness, as it is very demanding on the legs. While the glutes are the main target area, this exercise also works all thigh and hip muscles (e.g. hamstrings, quadriceps, etc). It even works the abs and lower back. Together, these muscles work together to allow the "bridging" of the hips to take place. Instructions for the supine bridge with one leg are listed below:

Begin in the supine position (on you back) with one knee bent. Extend your opposite knee. The heel of the extended leg should be about 2 or 3 feet off the floor. Place your arms by your sides, palms face down. Using only one leg, raise your hips off the floor as high as you can. Briefly hold the position, then slowly lower your hips and repeat the exercise. Be sure to perform the exercise on the opposite leg. Your head should remain on the floor at all times.
