Boot-camp style training is more popular than ever with classes offered at gyms and in a wide selection of exercise DVDs for training at home. Scientists at the University of Wisconsin, La Crosse Exercise and Health Program, analysed the benefits of boot-camp workouts. The results showed the average exerciser burned 9.8 calories per minute – almost 400 calories during a 40 minute boot-camp video chosen for the study. For a great workout that could help break a training plateau by changing your regular routine, choose a class that combines aerobic exercise with strength movements. These classes help weight loss as well as muscle building with pushups, squat thrusts, and arm curls to provide great interval training.
