Madonna's cranking things up as she continues her whirlwind tour for "Sticky and Sweet." Along with impressing The New York Times, who said that she "worked hard and showed it," she definitely left an impression on us as well. Looking at the aerobic routines onstage like rope-skipping and some serious choreography, you'd think that this show belonged to someone half her age.

Madonna has started the American leg of her tour with a bang! She's going to be performing Monday, Tuesday, Saturday and Sunday at Madison Square Garden.
