Rebuilding the Quad-Hamstring Co-Contraction
Quad Sets and Terminal Knee Extensions specifically retrain VMO firing patterns lost after ACL injury, while Heel Slides restore hamstring length under load. Together, they rebuild the co-contraction timing that protects your reconstructed ligament before progressing to full weight-bearing movements like Step Ups.
Why Single-Leg Control Is Your Real Benchmark
ACL reconstruction doesn't just repair tissue — it severs proprioceptive nerve endings that tell your brain where your knee is in space. Single-Leg Balance and Sit-to-Stand directly retrain this neuromuscular feedback loop, which is why athletes who skip this work re-injure at dramatically higher rates even after full strength returns.
Loading the Graft Without Overloading the Joint
This routine follows a proximal-to-distal progression — Glute Bridges and Clamshells load hip abductors first, reducing valgus stress before your knee handles Step Up demands. Track your Single-Leg Balance hold time each session; when you can hold 30 seconds eyes-closed, you're ready to increase Step Up height or add a tempo challenge.
