The Skinny Jeans Workout concentrates on core muscles, balance and posture. A cross between ballet, butt-burning stretches and light weight lifting, the workout involves the entire body.
The session is usually taught in bare feet, for maximum balance.
Some regulars, who have taken the hour long class, claim they've dropped up to two jean sizes in four months.
The Skinny Jeans Workout, and other programs similar to it, can be found at health clubs across the country.
While the specifics of the workouts may vary the goal is the same: It's all about zipping yourself up into the tightest jeans in your closet.
