Please note that exercising in proper postural alignment will increase your workout's effectiveness and substantially decrease your likelihood of injury. Therefore, correct posture should be maintained at all times during your exercise program.
1. Make sure your head is parallel to the ground and centered over your shoulders. 2. Bring your chest up. 3. As you bring your chest up, your shoulders must relax and not go up. Therefore, relax your shoulders down and back. 4. Tighten your abs by pulling your belly button to your spine. 5. Align your knees with your second and third toes. 6. Make sure your knees are not locked. There must always be a slight bend in them. 7. Stand with your feet spaced comfortably apart (usually hip width). 8. Stand with your body weight placed at the mid points of your feet.
