High-intensity interval training - Wikipedia, the free encyclopedia
High-intensity interval training (HIIT), sometimes referred to as Guerilla Cardio, is an exercise strategy that is intended to improve performance with short training sessions. HIIT 'sessions' are becoming increasingly popular among today's athletes as more studies are done about the benefits of this exercise method. |
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.
Studies by Tabata, Tremblay, and others have shown this method to be more effective at burning fat and maintaining or building muscle mass than high-volume, lower intensity aerobic work-outs.
I've always heard moderate cardio, i.e. normal jogging makes you small and weak and that this method is preferible. Basically, you do a warm-up then start sprinting for 30 seconds. Then run moderatly for 30 seconds. Then sprint; rest; sprint, etc. You can play around with the ratio, so it doesn't need to be 30/30 (seconds) (it may be 20/40 or so) and as you get good of it, you may add cycles to a total of 15 or 20 minutes (a cycle = 1 minute of sprint/rest).
I wonder if anyone here does this kind of workout. It's getting very popular.
Anyways, my running shoes are on and I'm leaving in half an hour to try it out. It's going to be hard!
