Get Fit with a 5 Class Pack from Training Mate. Training Mate is a circuit based 45 minute HIIT (high intensity interval training) class that uses a combination of resistance and cardiovascular exercises to burn up to 1,000 calories in a single session. The class is divided into four timed stations which youll complete with up to three partners. The goal? Push yourself as much as you can during each 45 second interval. No class is the same so youll encounter a variety of exercises and equipment such as kettlebells, dumbbells, suspension bands, bikes, rowers and even kangaroo jumps! These all work to improve your speed, power and endurance all while toning and strengthening the core.
