Orangetheory’s annual eight-week Transformation Challenge returns on January 13, encouraging members to improve their health through body fat reduction and muscle gain rather than solely weight loss.
The fitness franchisor’s 2024 challenge drew over 142,000 participants and is known for its results-driven approach, which starts and ends with two professional InBody scans and sees participants committing to a minimum of three workouts per week for six of the eight weeks. According to Orangetheory, participants typically achieve an average 8.6% reduction in body fat and a 2.6% increase in muscle mass.
Brittany Leboeuf, PhD and research scientist at Orangetheory Fitness, explained that the 2025 challenge is designed to help members prioritize healthy body composition and longevity while meeting their unique goals.
“A healthy body composition is a key marker of a high-functioning metabolism, which is proven to reduce the risk of chronic disease and supports a longer, more vibrant life – our guiding purpose at Orangetheory,” Leboeuf said.
Challenge participants will also receive weekly wellness tips and access to webinars hosted by Stronger U Nutrition. Registration costs $35 (in addition to regular class fees) and will remain open through January 26 via the Orangetheory app or at in-studio locations.
As an added incentive, the heart rate-based group training brand is offering new members a $50 discount on their first month when they join as a Premier member during January.
“The Transformation Challenge is about inspiring people to take that first step and then celebrating the incredible results – no matter where they’re starting from,” Orangetheory’s director of fitness design Rachel Vaziralli said. “Through our science-backed programming, OTconnect technology, and expert coaching, we help people form essential, healthy habits that last well beyond eight weeks, helping them be functionally stronger and live life with more energy.”
Orangetheory merged with former Anytime Fitness parent Self Esteem Brands last year, marking 2024’s most notable deal in the fitness industry. Now situated under Purpose Brands, the group is led by former TopGolf CEO Tom Leverton.
The popular group fitness franchise is also expanding in the U.S. and Saudi Arabia as it embarks on a new brand strategy highlighting inclusivity.
