Sideways plank walks challenge the body to stabilize laterally while coordinating cross-body movement. The core resists lateral flexion as the arms and legs step to the side. Why it’s effective: - Trains obliques and lateral stabilizers - Builds scapular stability under shifting load - Strengthens shoulders and wrists - Improves coordination for crawling and balance drills This variation teaches the body to be strong in more than one plane. | Primal Moves
