Advanced Swimming Kinematics
Calculate stroke rates (SPM), model distance per stroke (DPS), evaluate SWOLF efficiency scores, breakout speeds, and hydro-dynamic drag suit resistances.
Configure Parameters
By swimming with deliberate added hydrodynamic drag, neuromuscular fibers over-compensate. Once removed, you will feel exceptional water elevation buoyancy.
