Knee injuries are the #1 most common injury for skiers and outdoor enthusiasts. From torn ACLs and meniscus tears to chronic arthritis and persistent pain, they cut seasons short and end careers early.
But here's what most skiers don't realize: the majority of these injuries aren't random. They're a result of weakness, imbalance, and movement patterns that have been accumulating in your body for years — often without any serious warning signs, until something gives.
Your body develops compensations over time. Old injuries. Muscle imbalances. Years of repetitive movement. These deficits make you more susceptible to falls, pain, and breakdown — and they get worse every season you leave them unaddressed.
The knees take the hit. But the problem almost always starts somewhere else — your hips, your glutes, your core, your feet. When those systems aren't working together, your knees absorb forces they were never supposed to handle alone.
The good news: this is fixable. And it's far more preventable than most skiers think.
Most skiers assume that staying active is enough. But there's a significant difference between being "fit" and being "prepared" for mountain sports, like skiing and snowboarding. Hiking, biking, and lifting weights build a general base for fitness-- but they don't build the neuromuscular control, lateral stability, or single-limb control that skiing actually demands of your body. And that gap — between general fitness and ski-specific preparation — is exactly where most injuries start.
Skiing demands things that traditional workouts and most exercises miss:
Skiing loads your body laterally, rotationally, and diagonally — often all at once. Most of our everyday movements and activities are linear. That gap is where injuries happen.
When you hit an unexpected patch of slushy snow, ice, or bumps, your muscles have milliseconds to respond correctly. That speed is trainable — but only with exercises that challenge your nervous system, not just your muscles. And it declines with age if you don't train it deliberately.
Every turn is a single-leg event. By run five of a long day, your stabilizers are exhausted — and that's when ACLs tear and knees buckle. Generic training almost never builds this kind of endurance of the important stabilizing muscles.
Slowing-down, absorbing, and redirecting force is what your knees do constantly on the mountain. Most people train to accelerate. Almost nobody trains to decelerate. It's the gap that causes the most soreness and damage.
The solution is neuromuscular training — exercises that teach your brain and body to communicate better, so you move with coordination, efficiency, and control. It's the most effective approach for building strong, pain-free knees and a body that holds up season after season.
ACL Strong is built entirely around these demands. Every exercise, every progression, every phase exists because skiing, snowboarding, and outdoor sports require it.
ACL Strong is partnered with and supported by the National Ski Patrol, the Professional Ski Instructors of America, and the American Association of Snowboard Instructors - three of the most respected professional organizations in the U.S. ski industry.
These are the people who ski every day, in every condition, on the most demanding terrain. They use ACL Strong because it works - and because the consequences of injury in their profession are too high to leave anything to chance.
Over 6,000 skiers and snowboarders have followed this program. Patrollers, instructors, guides, and passionate recreational skiers - from first-timers to lifelong mountain athletes.
"My ACL Strong exercises saved me from an injury already! I had an impact where I landed on one foot with force and wasn't able to bend correctly. It could have been a recipe for injury - but it wasn't. I'm SO relieved that my knee was solid enough to stay strong under pressure."
Dr. Leslie is a physical therapist, strength coach, and lifelong skier who understands what it takes to protect your knees, build confidence, and keep moving with strength.
After years of helping people recover from injuries, rebuild strength, and return to the activities they love, she created ACL Strong to give skiers and outdoor enthusiasts a smarter way to move before pain, weakness, or injury takes over.
Her goal is simple: help you feel stronger, more prepared, and more confident every time you step onto the mountain.
This program is not random workouts or generic fitness advice. It is built around the real movement patterns, strength demands, and knee stability skiers need season after season.
You will learn how to train the muscles that support your knees, improve control, build resilience, and address weaknesses before they become bigger problems.
Whether you are returning after an injury, trying to avoid one, or simply want to ski longer with more confidence, ACL Strong gives you a clear plan to follow.
This is about protecting your knees now so you can keep doing what you love for years to come.

Real stories from skiers, patrollers, and active people who used ACL Strong to build stronger knees, better confidence, and more mountain-ready movement.
"I just turned 69. My knees haven't felt this good in 20 years. This has changed my life. I'm no longer thinking about surgery."
"I had been recommended to have two knee replacements. ACL Strong has helped me avoid surgery, for now. I'm skiing stronger this year than last. Thank you for the program!"
"This program made a difference in my strength, agility, and confidence on skis. I tore my MCL a couple of years ago, and even with extensive rehab, I always worried about it. ACL Strong helped me strengthen and get over that apprehension."
"Not only do they help your knees become stronger, they helped me rehab my recently sprained knee that previously had meniscus surgery. Thank you Dr. Leslie!"
"Even though I consistently work out, following the program helped my legs become noticeably stronger and ready to ski. The addition of balance work and a proper pre-ski warm-up were an added benefit."
"The training has made a big difference in my strength and conditioning this year - thank you very much for the fine program!"

The skiers who stay on the mountain into their 70s aren't lucky.
They made a decision - usually years earlier - to take care of their bodies in a specific, intentional way. They trained smarter. They addressed their weaknesses before those weaknesses addressed them. They invested in the foundation that made everything else possible.
This is that decision.
The mountain will be there. The question is whether your knees will be ready for it - this season, next season, and the one after that.
