RockBox Fitness Franchise

RockBox Fitness is franchised by SLLR Enterprises, LLC, a North Carolina company formed on March 16, 2017. The company began offering franchises on December 14, 2017. Its April 27, 2026 Franchise Disclosure Document records Roger Martin’s involvement as a managing member from the company’s inception, followed by leadership roles including Chief Executive Officer from August 2021. This provides a documented timeline for the franchise system’s development in the Cornelius, North Carolina area.

The concept is a membership-based group fitness studio built around boxing, kickboxing and functional training. Studios generally occupy approximately 1,800–2,200 square feet, with designated areas for different components of the workout. The operating system covers equipment specifications, studio appearance, marketing and management procedures. The required equipment and inventory arrangements include workout equipment, heavy bags, flooring, lighting, sound equipment and branded opening supplies.

RockBox also offers qualified buyers multi-studio development rights under a development agreement, with a defined opening schedule and a separate franchise agreement for each studio. These arrangements should be evaluated separately from a single-studio purchase. For a first studio, the disclosed initial franchise fee is $59,900. The initial advertising program is budgeted at $22,000–$29,000 and begins approximately 12 weeks before opening. Buildout planning depends on the premises, and the FDD’s leasehold-improvement estimates assume a material landlord improvement allowance.

Before opening, RockBox reviews proposed sites, provides standard building and layout guidance, supplies equipment specifications and approved-vendor information, and gives franchisees access to its operating manual. It also provides suggested staffing levels and hiring guidelines, advice on the market introduction plan and, upon request, review of the pre-opening business plan. Site selection, lease negotiations, permits and local compliance remain the franchisee’s responsibility. Opening assistance includes one or two representatives on site for three to five days.

The initial program combines virtual franchisee training, an in-person Training Camp and online RKBX University. The FDD’s training table lists 25 online hours, 39 classroom hours and 12 in-studio hours. Subjects include business ownership and operations, sales, marketing, customer-management systems and trainer preparation. Training generally takes place through the home office or a RockBox studio in the Charlotte, North Carolina area, with remote or on-site delivery available at the franchisor’s discretion.

For an entity-owned franchise, the principal and Designated Manager/Head Trainer must attend. The initial program carries no attendance fee, while the franchisee pays travel, living expenses and employee compensation. Additional personnel may attend; confirm the permitted group when scheduling. Personnel must finish training to the franchisor’s satisfaction at least 45 days before the soft opening. Opening is also subject to the required approvals and currently at least 150 paid presale memberships. The estimated period from signing to opening is five to nine months, depending on site, lease, financing, training and licensing progress.

Ongoing support includes recommended staffing and administrative procedures, operating guidance and advice by telephone or electronic communication when requested, to the extent the franchisor considers reasonable. There is an annual ongoing-training requirement, some of which may be completed remotely. A replacement Designated Manager must complete initial training, with a disclosed charge of up to $350 per day. Requested in-person operational support may cost $600 per day plus expenses. Owners make their own hiring decisions and remain responsible for running the studio.

RockBox administers a brand fund and maintains the brand website. The brand-fund contribution is the greater of $450 per month or 2% of monthly gross sales, with timing provisions in the FDD. Local advertising requires $1,500 per month, plus separate advertising-management charges that do not count toward that spending requirement. These obligations are part of the operating budget, rather than free marketing services.

RockBox Fitness offers a defined studio identity for a buyer interested in group exercise: boxing and kickboxing combined with functional training, a membership model and a consistent branded environment. The opportunity is particularly relevant to someone who enjoys developing a local customer base, leading trainers and sales staff, and maintaining a dependable class experience. Training in both sales and studio operations connects the fitness concept with the work required to run the business.

An owner may delegate daily management to a franchisor-approved Designated Manager who has completed the required training. The studio must remain staffed by a trained principal and/or the manager, and the manager must devote full-time attention to its operation. This makes management capability, staffing and local membership development central to the ownership decision. For a buyer who wants to build an actively managed fitness business using an established format, RockBox provides a specific concept to evaluate alongside local demand, lease costs and the full operating budget.
