As with all instructional exercise information, please use your discretion before attempting any of these workouts.
If you have a history of injury or are over age 40, please seek medical advise before attempting these workouts.
If at any point during the workout you experience pain, stop immediately and rest.
Do NOT overdo it! Regular exercise produces better results than a single extreme workout–which could lead to injury.
Always warm up before attempting any exercise and stretch post workout.
