Alternating Single Leg Bridge

In a nutshell, the idea is to hold yourself as absolutely still as possible, while at the same time raising one leg at a time up as high as you can, and then hold it there for one full second before alternating to the other leg. To get the most out this exercise, keep your elbows slightly bent the entire time that you are doing the exercise, and also do not let your back sag. You will get much more muscular activation as well as strengthening of the core stabilization muscles by keeping your elbows bent, maintaining a straight back, and lifting each leg up as high as possible for each repetition.
