But getting the star treatment from a certified Pilates instructor, like Society Hill's Brie Adina Neff, can be expensive. Neff says a one-on-one, hour-long session from a certified instructor can cost about $80.
There is a way you can save on the stretching, toning and strengthening of Pilates without straining your wallet.
Neff's Equilibrium Pilates (424 South 2nd Street) offers one-on-one sessions with apprentice instructors, who haven't yet completed their 600 hours of training. The cost: just $25 an hour.
Neff oversees the apprentices, while they gain the experience they need to become certified.
Both men and women are welcome. Some of Equilibrium's clients have included professional football players and dancers. But people who're healthy and injury-free make the best clients for the apprentices.
Deborah Zakheim, who's been a client for about three years, swears by the method.
She says it has improved her attitude, posture and body.
