Rear Leg Raises

Step 1. Place yourself on your hands knees on an exercise mat. Your head should be looking forward and the bend of the knees should create a 90-degree angle between the hamstrings and the calves. This will be your starting position.

Step 2. Extend one leg up and behind you. The knee and hip should both extend. Repeat for 5-10 repetitions, and then switch sides.
