So what do you do? For 30 seconds to 1 minute you push as hard as you
can and then you recover for 30-40 seconds after. Total workout time is
anywhere from 15-30 minutes (including warm up and cool down)
TurboFire has these, you can incorporate them into your gym routine on
an elliptical or treadmill or bicycle, or you can make your own!
By adding kicking, punching, jumping and anything else that seems fun
and pushing as hard as you can you can make your own HIITS!
