Get Fit for the Season, Avoid Injury, and Protect Your Knees so You Can Enjoy The Mountain Lifestyle for as Long as Possible

Discover How To Eliminate Knee Pain, Save Your ACL, And Shred Like A Boss This Season And Many More


Knee pain or ACL injuries seem almost inevitable when you're on the mountain year after year

If you’re like most of our members, you love the feeling of carving through fresh powder, crushing moguls, and exploring new terrain. First tracks, back-to-back days, and impressing yourself (or your kids!) are all part of the rush of being out on the slopes as much as possible through the winter.

The off-season brings more outdoor adventures in the mountains, rivers, deserts, and oceans. Whether it’s biking, climbing, hiking, paddling, or other outdoor lifestyle activities, we all want to keep doing what we love for as long as possible…

We need our knees to keep up for the ride.

But chances are, you know someone who has had a serious knee injury and never got back on skis. Or someone with arthritis so bad that it hurts to even think about sliding into boots or hiking across rocky terrain.

And you might already know this, but…

It’s frustrating to live with pain.

It’s disappointing to miss out when you’re hurt.

It’s scary to come back after an injury. 

And it’s discouraging when you can’t do what you used to do.

You may have wondered if you’re doing “enough” to maximize your fitness, protect yourself from injury, and maintain your lifestyle for as long as possible.

Most people think the best way to be “most prepared” is by working out harder. But the truth is, it’s not about how much you exercise, it’s about how you exercise.

Lifting weights and mountain biking are NOT enough. 

You need specialized, sport-specific exercises to teach your brain and muscles to communicate quickly so you optimize movement and stay out of danger. 

Unfortunately, most people aren’t doing this type of training because they either didn’t know it was possible, or they don’t know HOW (so they completely skip it!).

I get it, though. There are so many conflicting ideas about the BEST exercises to do and it can be overwhelming and exhausting to try to figure it out.

Dr. Leslie Exercise ACL Strong

With so many exercises to choose from, how do you know which ones are best?

You’re NOT alone…

Getting the most bang for your buck is tricky. We don’t all have hours to spend at the gym every day. And for some, the most important thing is just feeling good to enjoy the outdoors as much as possible.

“Injury prevention” isn’t talked about early enough. We should teach this in early adolescence…but instead, we wait until you get hurt to teach you the trick to not getting hurt. It doesn’t make sense.

So, if you ignore preventative exercise, and you don’t take a strategic approach to longevity or performance, your skills will plateau, your joints will degrade more quickly, and you’ll be faced with injuries or surgeries that could eventually force you into early retirement.

Honestly, I’ve been active in sports my entire life and never heard anything about “injury prevention”... In fact, it wasn’t until I became a Doctor of Physical Therapy that I discovered how EASY it actually is! My mind was blown. Why is nobody doing this??

Dr. Leslie Exercise ACL Strong

So here’s the cold, hard truth that nobody ever told you…

Doing The Right Exercises, The Right Way, Is The Absolute BEST Way To Protect Your Knees, Prevent Injuries, And Elevate Your Performance.

It’s PROVEN by years of research!

In fact, a systematic review with meta-analysis (basically this means ALL of the good research was compiled) published in the American Journal of Sports Medicine revealed a 53% reduction in lower extremity injuries reported after performing a 4-6 week “injury prevention” training program with sport-specific exercises that included agility, plyometrics, strength, and balance training. (Huang et al)

Plus, these programs can help reduce pain and improve performance!

Experts agree that these programs are HIGHLY UNDER-UTILIZED.

…mostly because people don’t know WHAT to do, or HOW.

And that’s exactly why I’ve made it really easy for you…

" I’ve helped thousands of athletes and active people of all ages overcome injury and take their performance to a higher level "

I know you have options when it comes to hiring an expert…

To give you some perspective, my patients pay me anywhere from $3000 to $7000 to guide them through rehab and back to their sport stronger over a 6 week to 4 month period. So, you could hire me one-on-one, but I’m limited on how many clients I can take on at that level and my waitlist is already so full that I’m actually not accepting new clients right now.

Or you could hire a personal trainer to take you through a ski or snowboard specific training program, but you will have to pay a premium price to get an experienced, qualified trainer who will keep you safe while you get stronger. Plan to spend upwards of $2000 for just the first 6 weeks, not to mention meeting early in the morning or late in the evening for scheduled appointments. And after 6 weeks, then what? You’ll be on your own again and you’ll probably have to spend that money again next year for pre-season fitness training.

Or you can try to unravel it yourself…

On the other hand, you could try to figure it out on your own and spend hours at the gym, wasting time on the wrong exercises, or even worse, putting yourself more AT-RISK by doing exercises the wrong way. And if you’re like most people, you’ll still miss the most essential components of training that will help prevent injuries.

Figuring out exactly which exercises to do can be totally overwhelming. There are so many websites, online videos, and unqualified people saying what TO do or what NOT to do. Who should you trust? The truth is, most of what’s available for free online is risky because it’s not designed with safety in mind, or with your specific goals in mind. I’ve seen a lot of people get hurt by following free advice online.

Don’t make mistakes that could cost you your knees. It's NOT worth it.

I designed this program to be a complete process to help serious snowsports enthusiasts make the transformation from being unknowingly susceptible to injury, to being stronger and more resilient, so they can simply do what they love, without being limited by preventable pain or injury.

My goal was to create an option for people who want to do this proactively, so they don’t have to get hurt in order to learn these life-changing strategies.

Your Most Popular Questions... Answered!

Below is a list of the most common questions that I have been asked. If you have a question that isn’t on this list, and you’d like it answered before joining ACL Strong, please send an email to our team at and we will be happy to give you the clarity you need to make your decision.

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
