This inner thigh workout by Cassey Ho is super quick and will leave your inner thighs burning. The workout is comprised of two moves, repeated about four times... I lost track after two. This workout is a must try on it's own or with some of Cassey's other videos. You can also do this after a cardio workout or run, or before your yoga session as a quick warm-up. Be prepared though, this is four minutes of pure inner thigh insanity!
