    BodyBUILDING B4 BodyBreaking is built around a specific philosophy, assessing how your body actually moves before jumping into physique-focused training, rather than following generic trainer advice without context. Members get an online self-assessment, a 250+ exercise library, joint and movement-specific programs, follow-along workouts, a "Trainers Corner" for other coaches wanting to grow their own business, and weekly office hours with Sam. Since it's free, this is a low-risk way to explore a mobility-first approach to bodybuilding.
