Biomechanical Trick Trainer

Mullen Protocol

A progressive framework built on biomechanical precision. Move through each phase sequentially, checking off drills as you complete them. Progress saves locally.

Phase I: Kinetic Calibration

Foundation & Board Feel

Establish your baseline. Before any trick progression, calibrate your body's relationship with the board. These drills build the proprioceptive foundation every advanced movement rests on.

Static stance hold - 60s eyes closed, find neutral balanceWeight shift oscillations - fore/aft 10 reps eachHip pivot drills - open/close 20 reps each sideAnkle flexion holds - 30s each foot, dorsiflexionKnee tracking alignment - mirror check, 10 slow squats

Heelside Slide Biomechanics

The heelside slide is the fundamental speed-check and stop. Master these seven steps in order. Each builds on the last.

Compress - drop into a deep squat, weight centered70/40 weight split - 70% front foot, rear foot light45-degree board angle - point the nose across the slopeInvisible chair - uphill lean with seated posture, hands lowDecompress - rise smoothly, transferring weight to rearKick-out - initiate slide by pushing rear foot throughPendulum return - bring the board back under you
