We give away a great, get-fit secret here.

Last week, we asked you to spill your secret, no-fail way to get fit in time for Memorial Day and bathing suit season. We've found a winner. Lucky Alexei MacPherson gets a summer's supply of Hint, the fruity, zero-calorie water that celebs love. And lucky us--because we get her swimsuit-ready secret!

Alexei writes, "My secret is Katie Osumi and her class, Coreplay." What makes it the best:

It's all-in-one. "The class incorporates Pilates, yoga, cardio, Lotte Berk [the hit ballet workout from the UK] and boot camp."

It's cruel to be kind. "Katie has a great attitude, so even though she kills your muscles, she does so with the sweetest voice and music, so you can't help but become a faithful follower."

It works. "Coreplay has a firming, lifting and sculpting effect unlike any other."

That takes the prize.

Coreplay, get the schedule and learn more here.
