HIIT

I have experienced various forms of HIIT in high school and in sports, and I don't really agree on its benefits. Our bodies do not adapt to rapid change very well. Even losing alot of weight in a short amount of time can bring on unhealthy side effects. HIIT in the long run can lead to joint problems and other injuries. Although doing HIIT is an effective way to reduce fat percentage and gain muscle, its long-term benefits are questionable.
