Oceanside CrossFit has been serving the Oceanside community for 4 years. CrossFit is the principal strength and conditioning program for athletes, police officers, and military personnel. Hence, a number of the trainers here are ex- or current military and police. They offer a one-on-one introductory session to learn about the program and decide which CrossFit process will be right for you and your goals. They incorporate weights, cardio, martial arts and much more.
