Cheap live music is a rare find these days. But if you hand over the cash for Madonna tickets, you're going to see quite a show. This pop rock dance diva has arrived in the U.S. on her Sticky & Sweet tour, and beyond Madonna-style dance moves and a killer song list, she's strutting her fitness prowess on stage with a jump rope.

Recently in New Jersey, she double-dutched, skipped a single rope and threw in a few arm crosses to emulate the pumping aerobic beat of Into The Groove. You must possess serious fitness groove to jump rope while performing on stage -- leave it to Madonna to deliver.

Jumping rope is not for the weak, it demands significant cardiovascular endurance, and for me, a sturdy sports bra. Boxers jump rope, not musicians. But thanks to a macrobiotic diet and a ravenous hunger for hours in the gym, Madonna shatters another fitness ceiling at the tender age of 50. You may dance and sing just like her, but if you really want to be a Material Girl, check out AOL Health for the basics on jumping rope.
