The Best Workout for a Knockout Body
How it works: Do as many reps as possible (AMRAP) with good form of each exercise for the prescribed amount of time. Each round uses a 2:1 interval ratio, with 2 minutes of high-intensity effort followed by 1 minute of an active-recovery strength move. Rest for 30 to 60 seconds after the strength move if needed. (If it’s too tough to hang for 2 full minutes at first, switch the ratio—1 minute cardio and 2 minutes strength—and add more rest as needed.) Perform the circuit up to 4 times total.
You will need: No equipment
