How Athletes And Outdoor Enthusiasts Stay Injury-Free By Focusing on Their Knees With Simple Exercises

Save Your Knees. Save Your Lifestyle.

A 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.

"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!!
Charity Russell
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!
