As they enter the training circle at Curves, female guests come face-to-face with the smiles of other women. And just as points on a circle share a common distance from the circle's center, workout participants share the experiences of those nearby, trading stations throughout the 30-minute training session. 30 seconds is spent on a piece of strength-training equipment and designed to work opposing muscle groups. Exercisers then move on to a cardio station, where they run, jog, or dance to maintain heart rates.
