The large "ROM" (Range of Motion) from kicking provides a very unique flexibility which will help to loosen hips, glutes and hamstrings along with the myo-fascia that holds these large muscles in place.  Integral nerve endings from our backs finish in the glutes and hamstrings so It's very important to develop a strong BUTT.

Did you know, 1 squat burns more calories than any other single human movement!
