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. Equipment Used Aerobic Steps The aerobic step is an elevated platform used during exercise. The height of the step can be tailored to individual needs by inserting risers under the step. The aerobic step is most commonly used for various bodyweight, plyometric and dumbbell exercises. Exercise Instructions Step 1 Start in a push-up plank position with your feet shoulder apart. Keep your back flat and your core engaged. Step 2 Place both hands up on to the step one after the other. Step 3 Walk your hands back down on to the floor.
