Founded in 2012, F45 Training, is a unique team training workout unlike any other. The workout merges three separate leading-edge fitness training styles – high-intensity interval training (HIIT), circuit training, and functional training – into one, consummate and compelling group training experience for its members. This fusion has led to the development of 36 unique 45-minute workout experiences, with additional workouts under development by the F45 Athletics Department.

F45 Training's daily workouts vary the amount of exercise stations, the work time/rest time ratio and the number of repetitions through a daily exercise circuit. This provides a challenging—and ever-changing—workout for its clientele. This combination of interval, cardiovascular and strength training has been proven to be the most effective workout method for burning fat and building lean muscle.
