Get the exact exercises you need and a proven system to help you avoid injuries so you can enjoy sports or compete at a higher level, without knee problems getting in your way

A major knee injury or torn ACL changes everything.

Rupturing a ligament in the knee, like the ACL (Anterior Cruciate Ligament), is not only excruciatingly painful, but emotionally heartbreaking, and usually season-ending for competitive athletes.  Most require surgery, followed by a year of recovery with extensive rehabilitation.  The social-emotional impact can be just as difficult as the physical, if not harder.

Too many young athletes miss out on high school and college opportunities as a direct result of a knee injury.  Too many people have to quit their sport because of knee problems or degenerative joint disease.

Worst of all, statistics show that after ACL reconstruction, most athletes don’t return to their same level of competition, 1 in 4 will re-tear their ACL, and 50% will go on to develop early arthritis. 

Don’t let this happen to you or your athlete, especially when “injury prevention” or “risk reduction” has never been easier.

Founder of ACL Strong and Injury Prevention Expert

Athletes in sports that involve lateral movements and quick changes in speed and direction are at HIGH RISK for a torn ACL and should be enrolled in the Classic Course for protecting their knees and improving performance on the field or court.  Researchers and experts agree that all youth athletes 12-25 years old should participate in this type of training.  Click Here to Learn More

ACL injuries and degenerative joint disease are all too common on the snow, even with highly experienced skiers and riders.  More hours on the snow = higher risk of knee injury and wear-and-tear on the joints.  Chronic knee pain and acute injuries take people off the mountain every year.  Snow athletes should enroll in the Snow Course prior to the beginning of the season and should continue with the maintenance exercises during the season.

Ski area employees will sustain fewer injuries on snow and ice.  We are partnered with PSIA-AASI and National Ski Patrol to support people working daily on the snow.  Click here to learn more about the Snow Course, and consider the Ski Area Program if you are part of a group or organization.

Soccer Teams, Basketball Clubs, and Ski Resorts across the world are reducing injury rates with ACL Strong by returning each year to complete the training as a group.  Group discounts are available and rate is determined by number of participants.  Contact us for a quote.

"This Program has taken my strengthening to the NEXT LEVEL!"

Dr. Leslie has done an amazing job creating ACL strong! As a fellow therapist, and bb coach, this program is both doable for the busy athlete and spot on in the training. I love the educational side, and the improvement I saw in our athletes in 4 weeks was awesome. Thank for your work!

After the first couple of weeks, my legs and knee felt stronger, and more importantly, my pain was gone. The videos were very detailed on how to do the exercises which made them super easy to do. Thanks Dr. Leslie!!!
Ron Kutsch
Ski Instructor from Colorado Springs, CO
Your program is so awesome! I was blown away! I really enjoyed the versatility of the different moves and explanation especially for those that don't have a Bosu ball or other professional equipment handy. Although my surgeons had done work for the US ski teams, I never found a PT that incorporated as many ski like strengthening moves as you. AMAZING! In fact a lot of us instructors have been excited to share our progress with each other in the locker room in the mornings. I can' wait to keep up this routine and do it all over again next season. I will forever be recommending your program thank you!!

Ski Instructor, Schweitzer Mountain Resort
Before I started the course, I had to push myself up off the floor. Now, I can stand up without having to pull myself up! I have had a torn ACL and two hip replacements, and someone just told me that I'm now walking better than they have ever seen me! This course is working!! Thank you again!

The girls had an amazing season, played at an extremely high level, and we finished the season ACL strong! I believe the core strength, stability, balance, and technique we train through your ACL strong program has helped keep us almost completely injury free.
Roy Snyder
Soccer Coach from St. Cloud, MN
With much of the emphasis on the core and hips, I received an unexpected benefit from the program that helped my hips! I had an old hip injury that bothered me for years, but sometime during the program I noticed the chronic, nagging pain I had was gone. So . . . thanks ACL Strong!
