RF Studios Rebounder Fitness Studio, South Beach: $40 Class

RF Studios is the rebounder fitness studio for people who want their trampoline cardio with a side of aerial silks and a eucalyptus steam room. The boutique sits on the ground floor of Southgate Towers on the bay side of South Beach, next door to Mr. Baguette. RF Studios, at 910 West Ave, Suite B, Miami Beach, lists its Rebound Jump trampoline fitness class at $40, and the same small studio also runs bungee fitness, aerial yoga, barre and floating sound baths.

Rebound Jump Fit is a music-driven class performed on individual mini trampolines. The class listing describes a mix of cardio, dance-inspired movement, strength training and full-body toning that works the core, legs, glutes and arms while challenging balance and coordination. The trampoline absorbs much of the impact, which makes it gentler on joints than jumping on a hard floor. No trampoline experience is required, and the instructor offers modifications so a beginner and a regular can share the same row.

RF Studios is strict about timing. Class sizes are small, priority goes to clients who are already in the studio, and the doors lock at the start of class, so traffic on the causeway is not an excuse. The listing for Rebound Jump asks you to arrive 10 to 15 minutes early for check-in and trampoline setup. Grip socks are mandatory in every class, and the FAQ also asks you to bring a water bottle, a bath towel and a photo ID.

Phones must be on silent during class, because the studio treats the room as a focused, peaceful space. If you want a progress clip of yourself bouncing, personal photos and videos are allowed only during the last 15 minutes of a class, and you are expected to keep other people out of the frame. Pets are not allowed inside. All bookings are final and non-refundable, so only reserve a trampoline if you are sure you can attend that day.

The Rebound Jump class is listed at $40. For a longer commitment, RF Studios sells five-, ten- and twenty-class packs, a drop-in option and two membership plans. The current promotion advertises unlimited month-to-month memberships from $179 with $0 initiation and no contract, with the offer running through October 31. The annual plan adds one complimentary 60-minute red-light body contouring session, valued at $500, plus a personal training session and an RF Studios fitness bundle.

Trampoline fans often come back for the other gravity-defying formats. Bungee Fitness straps you into a professional-grade bungee system for low-impact cardio and resistance work. Aerial Yoga and Aerial Stretch use fabric hammocks for spine decompression and flexibility, and the Floating Sound Bath suspends you in a hammock while crystal bowls play. Barre Abs, Barre Body and Barre Booty fill the strength side, and the studio also books massage, reiki and personal training.

The studio's signature class is the RF Method, created by Roya Siroospour. It blends low-impact cardio, balance, strength, endurance and flexibility, all set to throwback tunes. The method trains unilaterally, working the right and left sides to help the brain connect, and the class is done shoeless. If you enjoy the rhythm of Rebound Jump, the RF Method is the natural next class, since both lean on music and coordination rather than heavy weights.

Every drop-in and membership includes access to the eucalyptus steam room, which the studio describes as a way to open the airways after class, along with showers. Members also get complimentary guest passes each month, quarterly members-only events and discounts on services. If you plan to head to work or the beach straight after bouncing, bring a towel and a change of clothes, and leave a few minutes for the steam room before you go.

Parking on South Beach is famously tight, so read the FAQ before you drive. Metered parking runs along West Avenue, and the studio points drivers to the garage at 10th Street and Alton Road, across from the Whole Foods. Southgate Towers sits close to the bay, a few blocks west of the Collins and Washington Avenue crowds. Because the doors lock on time, leave a margin for finding a meter before you start counting down to class.

West Avenue runs along the bay side of South Beach, so start with a slow walk along the bay to watch the sunset over Biscayne Bay toward the downtown skyline. Flamingo Park, a few blocks east, has a public track and ball fields if you want to keep moving. Lincoln Road Mall, the pedestrian promenade lined with shops and outdoor tables, is a short walk north, and the ocean beach lies about a mile due east.

Book the class online, then pack grip socks, water, a towel and your ID the night before. Aim to walk in 15 minutes early so staff can check you in and set up your trampoline. During the warm-up, keep your bounces small and focus on pressing down through the mat rather than jumping high. Take the modifications the instructor offers for the first few songs, and save the bigger moves for the final rounds once your balance settles.

The class works for people who find treadmill cardio boring and want a sweaty session that feels like a dance party. Because the trampoline absorbs the landing, it is also a sensible choice for anyone easing back into exercise who still wants a hard heart-rate workout. Visitors staying in South Beach can drop in without a membership, while locals who already take bungee or aerial classes can fold it into an unlimited plan.
