Heart-pumping music drives workouts at NBgroupx, and owner Khristina Wrase—armed with a bachelor’s degree in exercise and sports science—calls upon dance-based Zumba and cardio pump moves to whip clients into shape. Staffers also motivate students with yogalates classes, which seek to combine flexibility-enhancing yoga workouts with core-building pilates routines.
Planet Fitness's massive, brightly colored edifices teem with aerobic, strength-training, tanning, and massage options, tailored to suit burgeoning buffs of all ages and abilities. After an intense muscle pummeling on the extensive selection of strength-training equipment and free weights, valiant athletes and masochistic vampires alike may bask in the unlimited artificial sunshine of the gym's tanning booths. Meanwhile, an army of shiatsu massage chairs stands at the ready, twiddling soothing robot thumbs and waiting to coax tension from tired tendons.
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 by trading stations throughout the 30-minute training session. One minute is spent on a piece of strength-training equipment built for feminine frames and designed to work two opposing muscle groups with a single movement. Exercisers then move on to a recovery station, where they run, jog, or dance to maintain heart rates and keep platforms in place during momentary losses of gravity.
