A great workout is a full-body workout that helps you improve energy levels, metabolic rate, strength and endurance. It should provide a wide variety of different exercises to keep you from getting bored, prevent overuse of a specific muscle group and stop your body from getting “used to” certain moves. A mix of circuit and high-intensity interval training (HIIT) style workouts geared towards everyday movement is gold. This combination burns the most calories in the shortest amount of time, plus it is fun and keeps you motivated. You will get this and more at F45 Training.
