At 9 and 10, the PENETRATION STEP arrives properly: the deep step between imaginary legs, the back knee lowering as the hips drive THROUGH (never a stop at the knee: the knee is a checkpoint, not a destination), head up, hands rehearsing their future holds. Pattern volume on air and pads builds the sport's central attack at perfect quality.
This session runs about 45 minutes on soft ground with a cushion or pad. The through-motion gets guarded above all (shots that die at the knee die at tournaments), and both lead legs get drilled. Finishing against humans stays at practice; the home job is a penetration step so grooved that coaches just aim it.
This plan was written for every 9 and 10 year old. ParentEdge writes one for yours.
Built around their game, their goals, and what they’re working on.
Depth and through-motion: a deep lead step past the opponent's line, the back knee lowering as a checkpoint while the hips keep driving, head up, finishing PAST where the opponent stood. The knee-as-destination stall is the error that dies at tournaments; the through-arrival is the graded cure.
They give the drive-through honest feedback: a cushion that must be moved teaches hips-through in a way air cannot, at zero risk. The pattern volume (hundreds of perfect steps monthly) is the home superpower; practice adds the human variables to a step already grooved.
Really: lead-leg symmetry at this age is cheap (the patterns are new) and priceless later (attacks from both sides double the offense and confuse every opponent). The dominant side will emerge naturally; the drilled parity keeps the other side dangerous forever.
