Any workout that involves alternative bursts of intense activity and fixed periods of less-intense activity or rest qualify as HIIT.
1. Efficient: You can fit a HIIT workout into a super-busy schedule. Whether in your lunch break, or straight after work, most people can find 15 minutes in their day to complete a session.
2. Effective: Research has shown that more can be achieved with 15 minutes of HIIT compared to jogging on a treadmill for 60 minutes. The effective nature of HIIT results from pushing yourself to your absolute limits for each exercise you do.
3. Diet-friendly: Those on a diet generally find it tricky not to lose the muscle they have gained through exercise while losing the pounds in fat. HIIT seems to preserve that hard earned muscle definition while also helping lose the weight.
4, Metabolism-boosting: Human growth hormone (HGH) is stimulated by 450% after completing a HIIT workout for a full 24 hours. Not only does HGH increase calorie burning, it also helps to slow the ageing process.
5. Boredom-busting: There’s simply no time to get bored during a HIIT workout. You have to work at capacity, testing yourself to the max. There’s no time for talking, and before you know it you’ll be done. Giving you the rest of the evening, or day to get on with whatever else you need to do.
the fact that is so quick means that it gets done - which is the no 1 criterion for an effective workout.
I love HIIT for the fact I can get a workout done in 15 minutes. And I do feel so great afterwards, very energized and proud of myself!
Wow - that fact about HGH stimulation is very impressive. Personally I don't like HIIT cos I hate to feel so exhausted, but I wanted to know some facts that might inspire me to do some.
