Let’s face it: boxing gyms are prime spots for getting out some pent-up aggression. All forms of exercise can relieve stress, as physical exertion releases endorphins in your brain, boosts your mood, and improves your sleep. But sometimes your stress meter is about to max out, and you need more than the usual combination of cardio and strength training. The competitive nature of boxing creates a far greater stress release than a standard gym visit. Lacing up the gloves gives you a safe way to punch away those nagging stressors, and the intensity of the workout creates an endorphin rush that rejuvenates your daily routine.
