Ski Season Prep: How to Protect Your Knees Before Bluewood Opens
Bluewood usually opens sometime in December, which puts Walla Walla skiers and snowboarders six to ten weeks out from their first chair ride. That's the window to get your legs ready. A lot of ski injuries happen to people who show up on opening day with the same legs they had in August.
This guide covers why knees are the weak link on the hill, what the research says lowers your risk, and a simple six-week plan you can start this week.
Why knees take the biggest hit in skiing
Skiing has gotten safer overall, but knee injuries haven't dropped at the same rate, and modern carving skis changed the pattern. In a study of recreational skiers hospitalized for knee injuries, every case involved the ACL, and nearly two-thirds also had damage to other structures in the knee (Knee Surgery, Sports Traumatology, Arthroscopy). The MCL on the inside of the knee is also commonly sprained, usually when a ski tip catches and twists the leg outward.
Most ski ACL injuries are non-contact. They tend to happen in a few situations:
Falling backward with your weight behind your boots. Your hips drop below your knees, the downhill ski keeps carving, and the knee twists under load.
Catching an edge. The ski grabs the snow and rotates while your body keeps going.
Landing back-seated. Coming off a roller or jump with your weight back puts a large forward force on the knee.
Research on ski racers describes the same patterns: slip-catch, dynamic snowplow and back-weighted landings (Sports Health review). All of them get more likely when your legs are tired and your balance is rusty.
Prevention training works
Neuromuscular training, meaning strength, balance, and jumping and landing practice, is one of the best-studied ways to lower ACL injury risk. Pooled studies show these programs cut ACL injury rates by roughly half (meta-analysis of 27,000+ athletes). Most of that research comes from field and court sports, so the exact numbers for skiing aren't nailed down. The ingredients still transfer directly: strong legs, good single-leg control, and a body that knows how to absorb force.
A 6-week ski prep plan
Train three days a week with a rest day between sessions. Each session takes 30 to 40 minutes. Do one or two exercises from each of the four categories below, and rotate through the rest across the week.
1. Strength: legs that can hold a ski stance
Rear-foot elevated split squat: 3 sets of 8 per leg
Romanian deadlift: 3 sets of 8. Strong hamstrings help resist the shin sliding forward, which is the motion that loads the ACL.
Slow step-down from a 6- to 8-inch box: 3 sets of 10 per leg, keeping the knee lined up over your middle toes
Side plank or Copenhagen plank: 3 holds of 20 to 30 seconds per side
2. Balance and single-leg control
Single-leg balance with reaches (forward, sideways, backward): 3 rounds of 30 seconds per leg. Progress to eyes closed or a cushion.
Single-leg Romanian deadlift: 3 sets of 8 per leg
3. Jumping and landing
Lateral bound and stick: 3 sets of 6 per side. Hold each landing for 2 seconds with soft hips and knees.
Skater hops: 3 rounds of 20 seconds
Drop landing from a low box: 3 sets of 6. Land quietly with knees tracking over toes.
4. Leg endurance
Wall sit: 3 holds of 45 to 90 seconds
Bike or rower intervals: 6 to 8 rounds of 30 to 40 seconds hard and 60 to 90 seconds easy. Here's why interval training works.
How to progress
Weeks 1 and 2, foundation: learn the movements with moderate weight and two-foot landings. Finish each session feeling like you had two or three reps left.
Weeks 3 and 4, build: add weight to strength work, switch to single-leg landings, and lengthen wall sits.
Weeks 5 and 6, ski-ready: make lateral work faster and endurance intervals longer. Cut volume a little in the last few days before your first day out so your legs are fresh.
On the mountain: habits that protect your knees
Warm up before your first run. Five minutes of leg swings, bodyweight squats and lateral lunges in the lodge or parking lot.
Get your bindings checked. Have a certified ski shop inspect and adjust them at the start of each season.
Call it before you're cooked. When your legs are burning and your form is slipping, take a break.
Don't fight a fall. Keep your arms forward and your feet together, and don't try to stand up until you've stopped sliding.
Ease in on day one. Start on runs below your usual level and work up.
Who should get screened before ski season
A pre-season check is worth it if you:
Have had ACL reconstruction, meniscus surgery or another knee procedure
Get knee pain on stairs, during squats or after sitting
Have one leg that feels noticeably weaker or less stable
Are coming back after a year or more off the snow
At BYLT, we test side-to-side strength, single-leg control and landing mechanics, then build a plan around what we find. For people coming back from surgery, blood flow restriction training helps build strength without heavy loads. Our sports performance and sports physical therapy programs are built for exactly this.
Skiing after ACL surgery
Your return to skiing should be based on testing, not just the calendar. In one well-known study, re-injury risk dropped by about half for each month athletes waited to return to sport, up to nine months after surgery. Athletes with more equal quadriceps strength between legs also had fewer re-injuries (Delaware-Oslo ACL Cohort, British Journal of Sports Medicine). If you're within a year of surgery, talk with your surgeon and physical therapist before you buy a lift ticket.
If you get hurt on the hill
Signs of a possible ACL injury include a pop at the moment of injury, swelling within a few hours, and a knee that feels like it gives way. Get it evaluated. If you suspect a fracture, go to urgent care or the emergency department first. For most other knee injuries, you can come straight to a physical therapist: here's how direct access works in Washington.
Frequently asked questions
When should I start training for ski season?
Ideally six to eight weeks before your first day on the snow. Even three or four weeks of consistent training helps.
How many days a week should I train?
Three days a week, 30 to 40 minutes per session, with a rest day between sessions.
Do I need a knee brace for skiing?
Most healthy skiers don't. Strength and single-leg control matter more. If you've had ACL surgery, follow your surgeon's guidance on bracing.
How soon can I ski after ACL reconstruction?
It depends on your testing. Research supports waiting until about nine months after surgery and having near-equal quadriceps strength between legs before returning to demanding sports.
Is snowboarding easier on your knees?
Snowboarders injure wrists, shoulders and ankles more often, while skiers see more knee injuries. Snowboarders still need strong legs to absorb landings, so the same plan applies.
