“The best cardio workout is the jump-rope double-turn maneuver. It’s intense: You’ll burn about 26 calories per minute! Do a basic jump for five minutes, then jump twice as high and turn the rope twice as fast so it passes under your feet twice before you land. This takes timing, patience and power. But you’ll get in great shape just by working at it.”
—Michael Olajide Jr., former number one world middleweight contender and cofounder/trainer at Aerospace High Performance Center in New York City
