In 2017, they opened their 100th location. In 2019, they reached $100 million in total revenue. They attribute their success to being trainers themselves and having a unique franchise model. Morgan and Devan Kline cofounded Burn Boot Camp (BBC), a boutique gym franchise known for its challenging 45-minute workouts, in 2012 after leasing an indoor gymnastics center and its parking lot. They were permitted to run camps indoors in the morning and outdoors on evenings and weekends. Devan, who previously played in the minors for the San Francisco Giants, said it cost them their last $600 in savings to get off the ground.
