No arms. Full sprint. Unstable overhead load. 🏋️‍♂️ Watch the athletes from anatomyofspeedofficial strip away arm drive and introduce the shifting weight of the Tidal Tank Classic, the lower body has zero room for error. It forces instant mechanical efficiency. The unpredictable water movement forces the core and legs to stabilize under extreme chaos. Once arm drive is restored, the sprint pattern feels incredibly fluid, light, and powerful. The human system thrives under constraints. 🌊 #tidaltank #tidaltanktraining #tidaltankworkout
