MUSCLES ENGAGED Abdominals The abdominal muscles (abs) provide movement and support to your core area. The deeper and closer to the spine the particular abdominal muscle is, the more effect over body posture it will have, and this often contributes significantly to a healthy back. 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. Exercise Instructions Step 1 Start on your stomach with your hands placed in a prayer position, making sure that your shoulders are in line with your elbows. Step 2 Keeping your hips tight, your glutes contracted and your back straight, lift your body up so that you are supporting your body weight on your elbows and toes. Step 3 Maintain this position for desired length of time or until the back begins to strain and your hips begin to sag.
