Tabata, named after Japanese scientist Dr. Izumi Tabata
A training method that's is incredibly simple yet should be so brutal if performed with purpose, the purpose part is pretty important.
The process is simple you work for 20 seconds and rest for 10 seconds, you repeat over a 4 minute period.
Have a 2 minute rest and perform as many sets as you like, not to many though cause it is dam tough.
In those 20 seconds pick 1 exercise or sometimes 2, ideally compound movements... they can be weighted or body weight. For example Kettlebell Goblet Squats and Slam Ball (using the kit we have a class)
But bare in mind It's all too easy to miss 2 seconds of the start of round 6 or 7 so do your self a favour and get primed and ready, those seconds are valuable!
