2. Boxing: I let my clients do boxing as I feel that it’s a great way to pump up your heart rate and increase sweating. Higher the heart rate the more calories they’ll be burning. Usually I instruct my clients to do one minute of punches or combinations usually on boxing pads but can also be done on a punch bag followed by 30 seconds rest. Usually I repeat this exercise several times until my clients are fit. Then I let them hold the plank in between rounds as an active rest.
