Risk Management Strategy for Proactive Leaders

Knee Injuries are the most frequent and costliest Injury claims for ski Organizations

From twisting on skis to slipping on ice, 60% of employee injuries in the workplace are a result of a slip, trip, or fall...and nearly one-third of injury claims involve the knees.

Torn ligaments, muscle strains, and arthritis are the most common injury claims for people who spend day after day on the mountain.

Knee Injuries are a Pain for the Employee, Employer, and Insurer

Chances are, if you’re reading this right now, you know that employee injuries are a cause of frustration. While you probably already have strategies in place to mitigate risk, still the reality is:

No matter how many signs, safety meetings, and reminders you have to protect employees, nothing replaces someone's internal strength, balance, and ability to Quickly React.

Most organizations expect employees to be fit and prepared for their job, but they don't give them a good plan to achieve that.

The truth is,

A preventative exercise program

is the MOST EFFECTIVE way to help employees physically prepare for being on snow and ice, so they are less likely to get hurt and have an expensive injury claim.

In just 6 weeks, the right exercise plan can help You:

By training like an athlete and strengthening properly, you will reduce stress on joints, amplify your fitness, and reduce the chance of sustaining a season-ending injury.

You might think that it's the employee's responsibility to be fit and prepared to do their job...
But, being fit for snow and ice is entirely different from everyday life, especially during the off-season, so they NEED specialized training to do preventative exercise effectively...

Most people don't know how to exercise correctly to get the results they need

Your on-snow employees are athletes,
and they should train more like athletes!

If you want your team to be fit for the season, to be more bulletproof and resilient, they need a detailed, step-by-step plan that can help them turn their weaknesses into strengths so they can work hard and enjoy another season

What used to be very challenging to implement to hundreds or thousands of employees, is now incredibly simple…


The ACL Strong


A simple system of at-home preventative exercises to help skiers, riders, and on-mountain employees save their knees, prevent injuries, and enjoy work-life more

Strengthening exercises


Warm-up routines

Movement Re-training

Footwork, Agility, and Reaction Time


Your employees deserve to know how to protect their knees (now and long-term)

..and you deserve to have a strong, healthy, thriving team with a lower injury rate

Employees Have Been Loving This Program for 5 Years!

I Believe in this program. It is the most important part of my skiing routine. I do not go out without doing the warm up and 3-4 days a week I complete a workout. Not only does it help me stay healthy, my ability to access muscles and movements needed to continue to improve my skiing is quicker and stronger. Thank you!
I suffered a minor calf strain last season, and was concerned about patrolling this season. However, after starting your program my legs felt stronger and much more prepared for the season. Each day I could feel my foundation getting stronger. As a patroller we must be prepared to be called into action at a moments notice, there isn't time to stretch or "loosen up." This program brought an increase in strength and confidence this season. Thank you.
I think it should be a prerequisite or incentive to employment to all employees when skiing or riding is part of their job.
Love this program and hope all my employees participate next season!

Give them the training they NEED to THRIVE On Snow and Beyond

Nearly 4000 participants have enrolled in ACL Strong, with many of our members returning every year for pre-season training!

During the 2021-2022 season, 48 ski areas and over 1000 participants enrolled! 

Our participants had 62% fewer knee injury reports compared to average for ski area employees!

That’s over $270,000 saved in knee injury expenses alone!

Plus, ACL Strong participants had 70% fewer ACL injuries compared to average for patrollers and instructors! (Viola et al)

During the 2022-2023 season, over 1400 participants enrolled in the Snow Course! 

Cost per claim for lower extremity injuries was reduced from $12,097 to $874, indicating a massive reduction in severity of injuries and injuryt-related expenses for the policy-holder and insurance payor.

Better pre-season training is a win-win-win for employee, employer, and insurance company.

If you could save someone from a torn ACL, or a catastrophic lower extremity injury, wouldn't that be worth it?

Feeling better, moving better, and so happy this was offered to me by my employer! I hope they offer it again next season!

I'm trusting my balance more.

These exercises really do strengthen (without torture). I'm trusting my balance more. The videos, narration, and text provided the perfect guidance. It’s something I've never done in the past (silly me) but will do going forward. I am feeling confident about the precise way to do these exercises and stretches.

RM, Ski Instructor

I started this ski season the strongest

I took last season off and was apprehensive if I would suffer much. I started this ski season the strongest I remember in a long time - and I 100% attribute that to ACL Strong! I even got a compliment from another patroller half my age - responding to a wreck with a toboggan at the end of the day, we skied top to almost-bottom without stopping. His legs were aching and mine were still STRONG. Thank you Dr L and ACL Strong!

Start the season stronger than ever, and finish with fewer injuries than ever!



If you’re like most of our partners were before they joined, you might have some doubts or questions. So let me address some of the questions I get most often:

“Some of our departments have higher injury rates than others. How do we control who signs up?”

You can give out the registration code to certain departments, or to your entire organization. It’s up to you! We start with a certain quantity of “seats” in the program, but we can always add more if they get filled up.

“We don’t even know who we are hiring until December? Is that too late?"

No problem! Registration in the Ski Area Program is open as long as you have seats available. Your employees can enroll and get started with ACL Strong as soon as they get hired. They will have unlimited access to the program through the whole season. Group access expires in July so we can reset for the next season.

How do we know if they complete the training or not?

You may assign a group leader to monitor sign-ups and progress of the participants in your group. Group Leaders get special access to reports and behind-the-scenes content so they can help promote a successful program for their team.

Our Members Know What's Up!

Love your program!

I am on a ski instructor team and the training has made a big difference in my strength and conditioning this year so thank you very much for the fine program!!

Eric H, Ski Instructor, Vail Resorts

I loved it!

I pride myself at being a higher level skier, as I teach steep skiing clinics and am a head coach for a junior competitive club. I also train other instructors in steep skiing. I do dryland exercises regularly and was willing to give your program a try. I loved it! It was simple and quick enough to add in to the day rather than replace an activity or workout. It also added a bunch of exercises I never have tried before. I was feeling stronger and more stable in my movements in all activities. I wanted to thank you for the opportunity to do your course and thanks for doing what you do.

GP, Instructor, Coach

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."

Chip Bair

ACL Strong for Life!

“Thank you Dr. Leslie for the ACL Strong program. I am 56 years old and have been skiing since 5 years old. This program re-focused my training on balance and proper knee alignment. ACL Strong for life!"

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
