We love Trophy Fitness Club’s Cardio Fusion. Burn up to 1,000 calories in this high-intensity, fat-burning class that promises total body toning through the use of punching bags, weights, trampolines, and stationary bikes. During the 90-minute routine, you move from station to station—a rotation that changes every week so you’ll never get bored. Who knew fitness could be so fun? Membership required.
