The Boxing Workout
The traditional boxing workout, which has you shuffling from bag work to jumping rope to push-ups and sit-ups, promotes a high level of caloric expenditure by engaging multiple muscle groups and offering little time for rest. But the built-in unpredictability of a fighter’s training session gives it a leg up on other workouts. McCall explains that there’s a reactive element to boxing; whether you’re dealing with an instructor calling out combinations or an opponent throwing punches, you have to think and move quickly. “And that reactivity leads to a heightened anxiety, which can increase blood flow and oxygen consumption,” he says.
