POWER PLAY

Explosive exercises like burpees – that require the switch from press-up to high leap and back again – are as effective at firing up the metabolism as all-out sprints, according to research from the American College of Sports Medicine.

Short on time? Blast out a 4-minute Tabata (20 secs on/10 secs off) burpee session to keep your body in calorie-burning mode long after you’ve regained your breath.
