Look straight ahead. Stand on the balls of your feet, heels bobbing, body loose. Now grab the handles, swing the rope and jump. How hard can it be? You did this in the third grade, right?
But jumping rope can be serious cardiovascular business. For some exercisers, the simple trick of swinging a line overhead and leaping -- repetitively -- provides a workout more intense than running or riding a bike.
"I credit most all of my athletic success to the jump rope," said Buddy Lee, a former Olympic wrestler from Arlington, Va., who started jumping at age 14. "It's a training secret of some of the best athletes in the world."
Lee cites fitness benefits such as better balance and coordination, increased cardiovascular capacity, quicker reflexes and full-body physical conditioning.
"Do 500 jumps a day to keep the dogs away," said Lee, who now runs the Jump Rope Institute, an educational clearinghouse for fitness information.
Whether your "dogs" are weak legs or a few extra pounds, proponents tout rope jumping as a quick way to whip into shape. In as little as 15 or 20 minutes a day, you can have an intense workout and potentially burn off hundreds of calories.
The Jump Rope Institute says that 10 minutes of jumping at 120 revolutions per minute is more efficient than running or swimming laps in a pool. At that pace, it would take 30 minutes of jogging to equal the aerobic workout produced from jumping a line, according to the organization's studies.
10 steps to jumping rope Sean Levesque, group exercise specialist for the Twin Cities YMCAs, said jumping rope is easier on the body than running. "You don't land on your heels," he said. "You're on the balls of your feet, jumping on two feet and absorbing the impact." Levesque, a former coach of an elementary school jump-rope team in Las Vegas, says it is accessible to all fitness levels. "Anyone can do it with a few minutes of instruction," he said.
