Start slowly and gradually increase the intensity of the exercise. This improves flexibility and helps your body prepare for the next workout. Keep a water bottle near you during your workout and throughout the day. Lower the intensity of the workout to a point that allows you to maintain good posture and your hands are only resting lightly on the rails for balance. This can lead to strain and injury with the muscles of the back being particularly vulnerable.
High energy is usually a code word for high calorie.
