FORM: Use a smooth and continuous lifting technique. It is important to feel the muscles you are working and not feel strain in other muscles. Do not lock your joints (knees and elbows): keep these joints soft while maintaining good posture. Do not continue with an exercise if you cannot maintain proper form and control.
POSTURE: Maintain a neutral spinal alignment. Stand or sit tall, activate your core muscles (suck in your belly button) and avoid arching, hunching or twisting your body.
Always consult a physician before beginning an exercise program. Discontinue an exercise if you feel any pain or discomfort.
