Brad Bose / CEO Co-Owner

Brad Bose, cofounder of XChange.Fit, has been committed to the art of “finding your X” for over 30 years. His roster of celebrities and elite athletes reflects his extensive education and expertise.

A graduate of Hope College in Holland, Michigan, Brad studied physiology while playing football and wrestling on a national level. Brad went on to play professional football in Chicago but suffered several injuries that retired him from contact sports. Rehabilitation from these injuries expanded Brad’s knowledge of physiology and passion for training. During this transition, Brad earned an MBA from Webster University in Northbrook, Illinois, and channeled his love of contact sports into competing as a bodybuilder. Brad placed in several local contests including MR. LAKESHORE, MR. CHICAGO and MR. ILLINOIS and was invited to be a consulting member of The President’s Council on Fitness.

Brad relocated from Illinois to Los Angeles and became a pioneer in the private fitness industry, consulting at Gold’s Gym in Venice, CA. Brad has launched and managed several other high-profile private training gyms in Los Angeles, where he has trained a large number of well-known Hollywood celebrities and has worked on various television and film projects…
