Blast Fitness

The Scene
Most Ballys stick to the basics for their design. Televisions broadcast silently above multiple rows of cardio machines; mirrored walls act as the primary decorative components. But thanks to high-energy television ads and low-impact membership premiums, this national fitness chain has steadily attracted a clientele bent on saving money while losing weight or gaining muscle.

The Workout
Using fairly standard strength-training equipment and/or racks well-stocked with free weights, the best of the trainers here, who are classified at four different levels, can be as skillful as those found at costlier gyms. For group classes, signature exercise options include Spinning and Powerflex, as well as a number of patented routines inspired by Tae Kwon Do.
