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. Back (lower) The lower back is often not trained because it is not visible in the mirror. If you have weak lower back muscles, there is nothing to help pull back against the spine, putting you at risk of developing poor posture (hunched over). Weak lower back muscles can also lead to lower back pain. Equipment Used Weight Plate A weight plate is a single solid piece of metal without rotating parts. Weight plates typically range between 1lb and 55lb. A bumper plate is a weight plate that is coated in rubber so that it can be dropped on the floor safely during exercises like the deadlift, snatch and jerk. Exercise Instructions Step 1 Start with your feet shoulder width apart and hold the weight plate in front of your body. Step 2 Twist side to side using the momentum of the weight to rotate your trunk from side to side. Step 3 Make sure to keep your core engaged and maintain a strong athletic stance throughout the exercise.
