SynergyFX is a unique Columbia gym that specializes in "sproing" classes. if you've never heard of sproing, don't worry — the staff is happy to teach newcomers the ins and outs of this up-and-coming workout.
Here's the gist of it: while "high intensity interval training" (HIIT) workouts are scientifically proven to be maximally efficient, they can also be pretty rough on your body (especially your joints). That's where sproing-style workouts come in. Sproing classes put you on a soft-surface treadmill that is easy on your knees, and instead of using heavy weights for strength training, you use your own body weight and spring-loaded resistance bands. Yelp reviewers say the workout is fun and accessible to anyone, whether you're a fitness buff or just wanting to stay active. If 'sproinging' doesn't sound like your style, never fear, as this gym also runs regular yoga and Pilates classes.
