This challenging exercise works on glute strength in multiple planes, one legged balance, and body awareness at the same time. Here I am demonstrating only sagital plane motion (pure front and back), but this can be done with the toe touching in different directions. For example, straight back, back at a 45 degree angle, and straight to the side. This is fairly advanced and must be done with proper form to achieve the desired results. When performing this exercise, there should be very little knee bend, and you should feel it primarily in the upper outer portion of your glutes. A less challenging yet still effective exercise is the "Clam", which will be featured on our next post!
