For his workouts Chris likes to do circuit training using a combination of dumbbell, medicine ball and body-weight exercises. He’ll start with the body-weight exercises with a rest period between each one, as the workout progresses he will increase the resistance from medicine ball to free-weights and shorted or remove the rest period between the exercises. He’ll focus on integrated movements like woodchops, one-leg straight-leg deadlifts, and multi-directional lunges. He’ll complete a circuit with no rest between the exercises except to change weights or position, then rest for two minutes after the entire circuit. This strategy allows him to keep his heart rate elevated while doing more work in less time. 7. Try all the latest fitness trends.
