Fitness 19 | 6,018 followers on LinkedIn. Fitness 19 was founded in 2003 by two fitness industry veterans who believed that the traditional health club model wasn’t meeting the needs of the vast majority people. They started Fitness 19 to give customers more of what they really want out of a fitness membership. The result is a simple, yet revolutionary fitness club concept: an extremely affordable, family-friendly facility that offers state-of-the-art cardio, strength and free weight equipment.
