As if going to the gym wasn’t bad enough, now I have to go in heels?

Crunch gym, which came up with “Cardio Striptease,” has just started a new class: “Stiletto Strength.”

At a recent lunch-time session at Crunch gym near Times Square, dancer Amber Efe demonstrated how to strut like a cat-walk model, pivoting on six-inch heels that would challenge even the most ardent follower of shoe king Manolo Blahnik.

"Imagine you're at the bar, raise one hand high like you're holding your drink," she told the class, music pounding as she acted the part of a club-goer working through a crowd.

"Don't spill the drink," she told the group, a mix of women who clearly had plenty of experience and others still tottering on shoes that didn't show much wear.

Yeah. Sounds like a real health-conscious workout. What’s next? Push-up Bra Pilates?
