The Whirlwind Ankle-Skip Cardio Craze

Trail Log · Movement Breakdown

Jumping rope — the exercise that makes you feel like a kid on the playground until about ninety seconds in, at which point you feel like an old locomotive engine that's been running too long. It's one of the most deceptively demanding cardio exercises in existence, and it requires nothing more than a rope and a patch of ground.

You hold one end of the rope in each hand, place it behind you on the ground, and swing it over your head in a smooth arc. When the rope reaches the ground in front of you, you jump — just enough to clear it, no dramatic leaps necessary. Find a rhythm you can maintain, settle into it, and let the rope dictate the pace. Different speeds and techniques — single unders, double unders, crossovers, alternating feet — introduce enough variety to keep things interesting and your coordination continuously challenged.

Jumping rope is extraordinary for building cardiovascular endurance, ankle elasticity, and the kind of rhythmic coordination that makes you lighter on your feet in every physical activity. A 150-pound person burns about 350 calories jumping rope for thirty minutes, which is impressive for an exercise that requires less space than a coffee table. It's also one of the best warm-ups you can do, because it gradually raises your heart rate, warms your shoulders and calves, and wakes up your nervous system all at once. Start with short intervals and build up, because rope jumping has a way of exposing cardiovascular fitness — or the lack thereof — with ruthless honesty.
