Hi All! I've heard a little bit about HIIT (High Intensity Interval Training) but I'm a little confused on where to find actual exercises, specifically for jogging. Has anybody ever used this technique? Also, I've heard about the 5:2 diet or the Fast Diet, where you "fast" (only get 500 calories two days a week) but eat normal the rest of the days.
Just wondering what anybody knows on these two items - any info is greatly appreciated!
