Get ready to light your lungs on fire with this relentless, fat-incinerating HIIT circuit from fitness and nutrition coach and author of The 30 Second Body
, Adam Rosante. It's a mixture of high-intensity cardio moves for anaerobic conditioning and plyo moves for raw strength and power. All the moves are bodyweight, so this can be done absolutely anywhere.
Do the first four moves back-to-back for 30-seconds each, resting only when absolutely necessary. Then, rest 30 seconds and repeat, this time stacking on the fifth move. Then, rest another 30 seconds and repeat, this time stacking on the sixth move. When you finish the 6th move, immediately go into a full out sprint, in place, for 30 seconds.
