Watch Shane’s ACL Story (Former Competitive Snowboarder)

There are more than 200,000 ACL injuries per year in the U.S. and skiing has one of the highest injury rates.

Even after rehab, 1 in 4 will suffer another torn ACL within the first 2 years after surgery and most people say their knee is never the same. They cite weakness, residual pain, and fear of re-injury as factors that stop them from skiing or riding again.

The worst part?

Knee ligament injuries are largely preventable and no one is doing anything about it.  UNTIL NOW!


A professional neuromuscular training program created by Dr. Leslie Desrosiers, PT to help you feel better,
move better, and safely protect your knees for a long career on the snow.

This online course includes:

“Purchase Includes Liftetime Access”


"A First-Class Program!"

Over 1500 members have joined ACL Strong and the feedback has been AMAZING!


Coach Linda is proactive about rehab with her basketball players, but found they often don’t have much time. She wanted a program that was easy and doable. After finding ACL Strong, Linda has now gone through the program with her players for three years and said it makes a big difference, seeing improvement in as little as 4 weeks.

“I really encourage you to do it as a team together.  It’s quick and quite effective.”

No one's time on the snow should be cut short by a preventable injury.

Critical movement and exercises to promote unshakable knees:


It's not enough to just be strong, you have to move properly and land safely


Quickness, Speed, and Mobility to improve performance and avoid injury


We offer a 30 day, no-questions-asked refund.  Over 1000 people have joined the ACL Strong program, and the feedback has been extremely positive.  Many people return each year to repeat the course!  The exercises are quick and easy to do, even for a busy student, parent, or athlete working multiple jobs.  We’re so confident you’ll love the course that if for any reason you are not satisfied with the course, we will refund 100% of your money.



Hi, I’m Dr. Leslie!

As a lifelong athlete, I not only dealt with multiple injuries myself, but also saw some of my most talented friends and teammates sidelined by knee injuries.

It was so hard for us to watch from the sidelines, but what else could we do?  We stretched before every practice and game.  Wasn’t that enough?

It wasn’t until I started working as a Physical Therapist that I realized the ACL injury epidemic in American sports, especially among females (who are 2-9 times more likely to sustain an ACL injury).  Worst of all, I learned that this injury was preventable, but most athletes had no idea what to do for prevention.

That’s when I made it my mission to help you enjoy the sports you love for as long as you want… without the fear of knee injury.

Please join me in the Snow Course so you never have to just watch from the lodge.

Dr. Leslie Desrosiers, PT


The only requirement is a resistance mini band.  We highly recommend a Balance Trainer (i.e. BOSU or dyna disc) to get the most out of the balance/stability exercises, but it’s not required.  There are alternatives provided if you don’t have a BOSU, such as a pillow, foam pad, or other.  We also show how to use a foam roller and stretching strap if you have access to one, but these are optional.  See our equipment page for more info.

The Snow Course is not intended for rehab from an existing injury without an evaluation by a medical professional or physical therapist first.  If you are cleared to play a sport and have NO precautions for weight-bearing, range of motion, jumping, and lateral cutting, then you can participate in the course.  We highly encourage participants NOT to push into pain during the exercises.  We provide modifications for most exercises and participants should choose the intensity that they can perform with good form (and no pain).  We emphasize quality over quantity.  If pain is noted during an exercise, we ask participants to follow these steps:  1) Check your form, 2) Decrease Intensity or Impact, and 3) If pain persists, then simply skip that exercise.  After ACL reconstruction, we recommend waiting 9-12 months to participate in the course.  Once you are cleared for running, jumping, and changing directions WITHOUT pain or limitations, then you may participate at 9 months post-op.

Yes, I love interacting with members.  You can email me for support any time!  I also encourage you to utilize the Facebook group for support.  Our Tribe is amazing and can help answer many of your questions as well.

Yes!  We encourage teams, departments, and organizations to do this training.  Pricing is based on number of participants and grants a one year license to all who register with the team or organization.  Complete our Team Discount form here (CLICK HERE) and we will email you the registration instructions and pricing details.

While the course is designed for individual participants, we understand that families may purchase the course to participate in together.  Doing the exercises together can be helpful for compliance, motivation, and keeping good form. Please keep the login credentials within your own family, as number of logins per day may be restricted and will impact tracking/progress through the course. 

The problem with searching for your own “injury prevention” exercises on Google or Youtube is that you are not getting a comprehensive program that addresses all necessary components of injury prevention.  It can be overwhelming to sift through hundreds of exercises, determine which are right for you, and make sure you are covering all aspects that are necessary for effective prevention.  You will likely stumble upon exercises that may or may not be appropriate for your level of fitness and body control. Choosing the wrong exercises, or doing exercises the wrong way, can be dangerous and may lead to injury.

Yes, you can log in from any device including your desktop, tablet, or mobile phone.

Purchasing the course gives you a personal license with lifetime access.  If you are a team or organization, purchasing the course grants you access for 1 year.  The best way to continue to reduce injuries each year is by returning to this program with your team or organization each year.  Please see our Team Inquiry page.

A long-term maintenance plan should include continuing with neuromuscular training exercises for about 15 minutes, 2-3 times per week during pre-season and through the duration of the season.  There are a couple of options to do this:

  1. Participants can repeat the course from the beginning, choosing the options/modifications that are appropriate for them.
  2. Participants can select exercises or modules from the course to repeat 2-3 times per week.
  3. Participants can choose to upgrade to the VIP Club membership, which holds the entire library of neuromuscular training exercises in the ACL Strong Vault, as well as a monthly routine, and a featured exercise each month.  You can utilize the “Vault” to create your own routines. 
  4. Repeat the Snow Course before each winter ski/ride season.
