Playboy Playmate Holly Madison works up a sweat using the latest innovative gym workout ‘Reebok’s Jukari Fit to Fly’ at the Reebok Jukari Studio in Hollywood yesterday (April 10).

The “Girls Next Door” hottie looked like she was in the zone as she worked her way through a battery of exercises, looking uber-hot all the while.

Miss Madison showed off her killer muscle tone in a red tank top teamed with a pair of black stretch pants, red striped tube socks, and red and grey sneakers.

And now that she’s done with “Dancing with the Stars,” Holly says she’s already on to her next project.  “I’m working on developing my own reality show that I’ll also produce.  It’s going to be about me and my friends.”
