This core sequence combines instability and suspension to challenge control, coordination, and true trunk strength.🔥 The TRX pike on BOSU demands full-body tension while managing balance and position. The TRX side crunch on BOSU adds rotation and lateral control under instability. Nothing here is rushed. Every rep is about staying connected, resisting momentum, and maintaining control. This is how I train the core to be strong, defined, and supportive of every other lift, not just tired.💪🏼 Sa
