<br>Is this reported benefit of high-intensity interval training too good to be true? High-intensity interval training, known as HIIT, has become the "it" way to work out in recent years, [Prime Boosts Official Website](http://jimiantech.com/g5/bbs/board.php?bo_table=w0dace2gxo&wr_id=506087) as studios and gyms capitalize on the quick, effective method of training that alternates between bouts of intense activity-such as sprints-with periods of less-intense active recovery or complete rest. Fans of this super-efficient workout style swear by its ability to burn calories, target fat, and build muscle-all in much less time than a 5-mile moderate-intensity run. Another purported benefit of HIIT is your body's ability to stay in metabolism-boosting mode long after your workout. Known as HIIT afterburn, this process can boost your metabolism and keep you burning calories for up to 24 hours post-exercise. It's a theory many HIIT-based studios tout as a major health benefit of their workouts, promising you'll reap the benefits of their one-hour fitness classes for days.<br> |
