8 exercises using the Tabata Method -- great for all levels! Give all you've got for 20 seconds, then take a 10 second break. No equipment needed.

Tabata, a style of HIIT (High Intensity Interval Training) or HIIE (High Intensity Intermittent Exercise), is a short intense workout that burns energy/calories. It can be used to train cardio, strength, pretty much anything. And the best part? In 20 minutes or less you can get a complete total body workout. Tabata started out in 1996 with a speed skating study done by Izumi Tabata. The research proved a large gain in V02 max, otherwise known as your ultimate fitness ceiling. Unlike a HIIT style workout, Tabata has a protocol of 20 seconds on and 10 seconds off. This is repeated for a total of 4 minutes, then recovery. These 4 minutes are considered one round. And the rounds are manipulated to make the workout easier or harder.
