We sit on our glutes and hamstrings all day long, they deserve a bit of attention for all the neglect we give them. Dr. Brett McIff with the Utah Department of Health shows how a hamstring leg up is a great way to work the muscles on the back of the thigh.
Lie on the floor with your knees bent. Extend one leg up towards the ceiling, pushing the heel as high as possible. Using the other leg, drive your heel into the floor and raise your hips toward the ceiling. Want to make this a bit more challenging? Put the bottom foot on a stable raise platform like a couch. Repeat 8-12 repetitions, 1-3 sets on each side.
