High-intensity interval training
- High-intensity interval training
High-intensity interval training (HIIT) or sprint interval training is an exercise strategy that is intended to improve performance with short training sessions.
A HIIT session involves a warmup period, several short, maximum-intensity efforts separated by moderate recovery intervals, and a cooldown period. The period of alternating effort and recovery intervals typically lasts a total of 15 minutes.

HIIT is somewhat counter intuitive in this regard, but has nonetheless been shown to burn fat more effectively. There may be a number of factors that contribute to this, including an increase in RMR, and possibly other physiological effects.]References
