If you experience pain or dizziness at any time while exercising, stop immediately and begin to cool down.
doing a toning workout, and 30 seconds after each set if you are doing a weight loss workout. Plan to spend the first couple of weeks familiarizing yourself with the equipment and learning the proper form for each exercise. COOLING DOWN End each workout with 5 to 10 minutes of stretching. Include stretches for both your arms and legs. Move slowly as you stretch—do not bounce. Ease into each stretch gradually and go only as far as you can without strain.
