Is this the next exercise fad?

Likes jumping rope and ice cream.

Traditionally the turf of the boxing ring and schoolyard, jumping rope is nearly perfect exercise in terms of conditioning, cost-benefit and convenience, William Hamilton writes in the Wall Street Journal.

"To coordinate that kind of rhythm, the whole body has to be in sync—core, shoulders, legs," said Brian Nguyen, the actor Mark Wahlberg's personal trainer. Mr. Nguyen trained with Mr. Wahlberg for his role in last year's film "The Fighter." "It's a very intense movement for the body," he explained. 

Jumping is also gentler and kinder, though. "You're getting the most bang for your buck, because you're working almost every part of your body, but there's not the impact of running, because of the way the foot lands," said Alexis Colvin, an assistant professor of sports medicine in the Department of Orthopaedic Surgery at Mount Sinai Medical Center in Manhattan.

So then Hamilton gets down to technique.

John Snow, the manager of Trinity Boxing Gym in Lower Manhattan, has basic pointers. He has me jump in place, without a rope, practicing my arm movement: elbows to my sides, turning the wrist and bending and rolling the elbow, breathing through my nose, setting a pace, staying focused and loose. Mr. Snow called it "controlled relaxation," an eloquent attitude towards life, as well as rope jumping.

"An eloquent attitude towards life." I like that. I think Moose Tracks ice cream is an eloquent attitude toward life.
