Introducing: The Snow Course

What's Inside The ACL Strong Snow Course

Our members return every year to be guided through the most up-to-date training plan in the industry. Designed specifically for skiers and snowboarders, this is a snapshot of what you'll get in the latest version of the Snow Course...and you can do it ALL from home, on your own schedule.

The Intro Module

Weekly Exercise Modules

Each module includes a Dynamic Warm-up to get your body primed and ready for activity, followed by 4 simple exercises that will help you become stronger, more balanced, quicker, and more flexible. You’ll practice keeping your knees in a safe position when you weight-shift or land, so you don’t get hurt. Each module slightly advances from the previous just as your body begins to adapt and get stronger!

Bonus Challenge!

Two more modules make for even more awesomeness and a complete 6 week training program! Once you get through the first 4 modules, you’ll be ready to take on the bonus challenge with ease. These modules will further enhance your strength, balance, and body control, solidifying the gains that you already made.

We designed this course specifically for skiers, riders, and snowsports enthusiasts who are serious about enjoying the snow for as long as possible, without achey knees or torn ligaments.

Our Members Know What's Up!

Great Course! Very Beneficial!

"I tore my ACL years ago and have two hip replacements. Before I started the course, I had to push myself up off the floor. Now, I can stand up without having to pull myself. I don’t have pain and people tell me I’m walking better than ever! Thanks for a great course!"

Jim Bredy

ACL Strong Rocks!

"ACL Strong rocks! I’m already feeling stronger in my legs and more agile. I no longer feel the pain and stiffness that I had before. Thank you!!"

Exceptional Value

"I feel there has been a noticeable improvement in my strength and balance. The format was easy to use and only took a little dedication from me. Great customer support and service to say the least! Thanks again for providing the exceptional value of the ACL Strong program."

ACL Strong for Life!

My Control and Balance are Better

"I started with the ACL Strong program about 18 months ago and have noticed great benefits. My skiing is better...my control is better...my confidence is better.... and my knees don't hurt as much."

How much does it cost?

The mistake most people make is they don't want to spend time or money on a fitness plan or "prevention", especially when they are feeling good...so they don't. Or, they think they can just do it on their own.

...But, figuring out how to strengthen the right way and even "bulletproof" your knees is a big job. So when you don't do it right, you end up getting hurt, and then your doctor's appointments, medical equipment, and time off work will cost you much more time and money in the long run.

...Not to mention a LOST SEASON, thousands of dollars in medical expenses, and a year of rehab if you tear your ACL...ouch.

Maybe you just want it all figured out for you, so you don't miss anything. You might think you need "in-person" training at a gym or clinic. These programs are typically quite expensive and they require a much greater and stricter time commitment.

If you 're like most of our clients and you want convenience, flexibility, and the MOST benefit out of the least amount of work, then an expert-guided home program is the way to go.

This is your chance to join me and thousands of other ski and ride professionals as we get fit, prepared, and bulletproof for another epic season on the mountain...without going to a gym or wasting time on the wrong exercises.

Frequently Asked Questions

The only requirement is a resistance mini band.  We highly recommend an unstable surface or 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 access to this, such as a pillow or foam pad.  We also show how to use a foam roller and stretching strap, but these are optional.  See our equipment page for more info.

You can enroll a group in 3 easy steps:

One: Complete our Ski Area form or Team Discount form.  We will connect via email and provide a quote for your group.  Once accepted, we can send an invoice and get started!

Two: You will receive Registration instructions for your group members to self-register on the website.

Three: All participants will have access to the program immediately and through the entire season (up to one year)!

***For staying bulletproof long-term, we recommend repeating the program every year, starting pre-season.

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!  I encourage you to utilize the Facebook group for support as well.  Our community is amazing.

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.  Contact Us for a quote!

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.

Now we have an app!  Be sure to download it from the AppStore or Google Play Store.

Purchasing the course independently gives you a personal license with lifetime access. 

If you are a team or organization, purchasing the course grants you access for up to 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.  There are a couple of ways we recommend to do this:

  1. Repeat the course from the beginning, choosing the best options/modifications for your current level.
  2. Select exercises or modules from the course to repeat 2-3 times per week.
  3. Repeat the Snow Course or Classic Course before each season of your sport.
  4. Upgrade to the Elite Membership to gain access to more exercises, trainings, and office hours with me, Dr. Leslie, so you can stay strong ALL YEAR.  Plus, you’ll automatically get access to the newest Snow Course and Classic Course every year! Click Here
