MUSCLES ENGAGED Obliques Many people put a lot of focus on working their abs but forget their surrounding neighbors; the oblique muscles. Obliques serve as stabilizers, and are used in almost every physical activity. Exercising your obliques should be a very important part of your workout program. Glutes Gluteal Muscles (Glutes) are one of the strongest muscles in the body and are the connecting point between your legs and back muscles. Glutes are used in a variety of actions from moving the leg to extending and rotating the hip, as well as extending and rotating the trunk of the body. Exercise Instructions Step 1 Start in the side plank position keeping your hips up and your glutes contracted, maintaining a solid bridge. Step 2 While holding the side plank and keeping your hips up, raise and lower your top leg. Step 3 Repeat action for desired number of repetitions or until you are no longer able to maintain a solid bridge.
