High intensity interval training, often abbreviated as HIIT, is an athletic training style composed of short bursts of activity coupled with periods of rest. An example of high intensity interval training is 45 seconds of work, 15 seconds of rest for 30 rounds.
The benefit of this style of training is it is fast, efficient and can help participants still reach their weight loss goals while not having to dedicate themselves to an hour long work out. High intensity interval training is completed in 30 minutes or less and uses primarily body weight movements only.
HIIT can work as an excellent source of cross training for those involved in athletic programs or triathlons. It can be used as an active recovery from a CrossFit or Strength session or it can be performed successfully as a work out regimen by itself and can help improve cardiovascular efficiency. HIIT is available to all body types and fitness levels and can be modified easily for the individuals needs. HIIT is a great program for those looking to lose weight or tone up as those who participate in 30 minute HIIT sessions will still be burning calories for 24-36 hours after the work out.
