I picked this up from an email and was impressed with how inclusive it is. I think I now know twice as much about High Intensity Interval Training as I did before I read it.
On the subject of HIIT, the September 12, 2016 issue of Time magazine says, ” Martin Gibala, an exercise physiologist at McMaster University wanted to test how efficient and effective a 10-minute workout could be, compared with the standard 50-minutes-at-a-time approach. The micro-workout he devised consists of three exhausting 20-second bouts of all-out, hard-as-you-can exercise, followed by brief recoveries. In a three-month study, he pitted the short workout against the standard one to see which was better.
To his amazement, the workouts resulted in identical improvements in heart function and blood-sugar control, even though one workout was five times longer than the other. “If you’re willing and able to push hard, you can get away with surprisingly little exercise,” Gibala says.
