Good posture supports the body to function effectively and will minimize muscle strain and injury. During exercise, whether you are sitting or standing, your body will potentially be in several different positions. If you add weights, such as dumbbells used for strength training, or increase your exercise intensity to an energetic level remember to maintain proper form and posture. If you are negligent on your posture or form, you can easily sustain an injury and be sidelined. Take time to learn proper body alignment and be mindful about how your body is feeling. Pain could be a warning of incorrect form or posture.
