This routing will provide a whole body workout in a short 20 minutes period. Switching the exercise to the different groups of muscles allows cutting the time on breaks, thus making it more intense but without overloading. If you are in a good physical shape you may consider making the exercises more intense by wearing an ankle weights and holding dumbbells during the lunges.
