One of the key principles of the Metamorphosis program is the concept of "muscle re-patterning." This refers to the process of re-educating the muscles to work together more efficiently, and to fire in a more balanced and harmonious way. During days 11-20 of the Hipcentric program, this process is accelerated through the use of more dynamic and multi-planar movements. For example, exercises such as the " Hipcentric Lunge" and the "Glute Bridge with Leg Lift" require the muscles to work together in a more integrated way, engaging the hips, glutes, and lower back in a more functional and efficient manner.
