To spice up a fitness routine, professionals will wear bedazzling outfits or substitute their partner for a burlap sack filled with fireworks attached to a timer. Go for the pros with today's Groupon: for $25, you get five adult fitness classes at Dany Holdstein’s Two Worlds Dance & Fitness in Greenvale (a $100 value). All five classes must be used within a month of redeeming your Groupon.

At Dany Holdstein’s Two Worlds Dance & Fitness, students step, pedal, and shimmy toward fitness goals during expert-led movement classes. The schedule brims with more options than a precocious voicemail system, including all-level cardio kickboxing, step aerobics, and circuit training. Ballet-barre workouts build strength, flexibility, and endurance with deep stretches and low-impact movements, and patrons at indoor cycling sessions torch calories atop Star Trac Spinner Pro bikes.
