The ACL Strong program helps skiers and riders protect their knees through specialized exercises so they can stay healthy and keep doing what they love. ACL injuries and chronic knee pain can end your career on the snow earlier than planned, but a neuromuscular training program is proven to reduce your chance of injury and improve performance.

The ACL Strong Snow Course will guide you through a 4-week progression (plus 2 bonus weeks!) with the exact exercises that will help you feel better, move better, and be more resilient against injuries. The weekly routines take about 15-20 minutes to complete and should be performed 2-3 times per week. The course begins with foundational movement patterns and gradually increases in intensity and complexity of movement.

Whether you are brand new to injury prevention training or you’re an expert and want to learn new strategies to help your students and/or colleagues stay safe, this program will teach you why knee injuries occur, how to protect yourself long-term, why technique matters, and how to be more aware of your body alignment and position.  Through a strategic progression of simple exercises, this course will help you improve:

  • STRENGTH through the legs, hips, and core
  • BALANCE on a dynamic surface
  • LANDING MECHANICS for jumps and turns
  • AGILITY for reacting and changing directions
  • FLEXIBILITY for performance and recovery

Wondering what equipment you will need? A resistance mini band, as well as a balance trainer (aka unstable surface), are required to get the best results from the ACL Strong program. We recommend a BOSU Balance Trainer.  Alternatives include a Dyna Disc, Foam Pad, or simply a pillow. Throughout the course, we may introduce some other items, such as a Foam Roller and Stretch Strap, for those who have them available, but these are NOT REQUIRED. Visit the ACL Strong Equipment page for more information or to order equipment.
