Effective exercise can generate powerful huge forces if they are initiated controlled and dominated by the hip. Many untrained athletes have a muted hip which creates postures and mechanics that reduce power output, promotes postures and mechanics that are considered by many to be unsound. In simple terms the Muted Hip Function (MHF) results from the legs compensating for the failed of the hip, in effect using leg extension to compensate for non existent hip extension. According to the Crossfit Journal the causes and consequences of MHF include but are not limited to: • structurally disadvantaged spinal posture • low glute recruitment • low hamstring recruitment • pelvis abandoning the spine and chasing the legs • centre of gravity shifting dramatically backward • centre of balance shifting toward toes • knee experiencing unsound shear force • leg extension being the only productive effort • hip extension not being possible with low hip angle • pelvis rotating the wrong way The cure is deliberate and focused training. Thats what Crossfit London is for!
