For a high-velocity workout that absolutely destroys fat, just grab battling ropes.
Making a variety of “waves” with these heavy, long ropes provides a killer low-impact cardio workout. And since your shoulder, arms, and core will spend a prolonged time under tension, you’ll build muscle, power, endurance, and mental toughness.
Gaddour recommends going all-out for 20 seconds, making as many waves as possible, and then resting for 40 seconds. Do this for 10 to 20 minutes straight to keep the intensity high and to get an amazing aerobic and anaerobic workout.
