HUMAN DYNAMIX · KNEE PROTOCOLS

The ACL Protocol

Protect the ligament. Train the landing. Trust the cut.

Most ACL injuries happen without any contact at all, which means most of them are trainable. This protocol follows the same structure as the strongest injury-prevention research: foundational strength, landing technique, controlled power, then a full return to cutting sport.

The ACL Protocol

YOUR STARTING POINT

A program for your knee.

footballers, basketball and handball players, skiers, and anyone in a cutting or jumping sport who wants to reduce ACL injury risk, or who has been cleared by their surgical team for late-stage return-to-sport training.

Educational content. Not medical advice. This program is not for early post-surgical ACL rehabilitation or a suspected acute ACL injury — see your surgeon and physiotherapist for those.
