20 seconds on and 10 seconds off. Option Is to use the 10 seconds to do another exercise such as an isometric/strength/cardio instead of recovering. Do 8 rounds for a total of 4 minutes. Make it as hard or as easy as you need it.
Do this workout with the best exercise equipment. We recommend using a bluetooth chest strap heart rate monitor or a smartwatch for more training optimization & performance tracking.
