HIIT involves short bursts of intense exercise alternated with low-intensity recovery periods. Research has shown that this type of training produces significantly greater reductions in the fat mass of the whole-body as compared to other training protocols.
Standard HIIT regimens use a single exercise, like a stationary bike or treadmill, and simply alternate high and low intensity periods. In contrast, the bootcamp model employs several exercise variations and alternates high intensity with one exercise followed by low intensity with another. The outcome, a whole body workout with greater overall results that never gets boring.
