How to Get Ski Fit Before Your Season
You'll ski 80+ days. Your knees will know if you didn't prepare.
A ski holiday is 5 days. Your body can muddle through 5 days. A ski season is 80 to 120 days, and your body cannot wing that. Arrive unfit and you don't just ache — you lose weeks while your legs catch up, you compensate with bad technique that breeds injury, and you spend mornings wondering whether to ski on sore quads or take yet another rest day.
An injury in week 1 is catastrophic in a way it never is on a holiday. You've paid for flights and accommodation. You need the job. You can't just go home and rest for a fortnight. This is the version of "get fit before your season" that holidaymakers never need to hear.
Here's what skiing actually demands — and how to build it.
What skiing actually loads
Quads are the primary engine. They absorb impact on every landing, hold you in the skiing position (a sustained partial squat), and control speed on steep terrain. Unconditioned quads blow up in the first two hours of day one. Then they're sore for three days. Then you ski on sore quads, and so it goes.
Glutes and hamstrings — the posterior chain — provide stability that protects your knees. Weak glutes means your knees take the load they shouldn't. This is the most common pathway to ACL damage and overuse knee injuries in skiers.
Core is the central stabiliser for every turn. Weak core means inefficient, effortful skiing and lower back pain by week three.
Cardiovascular capacity matters more than most gym programmes address. High-altitude resorts sit at 1,800 to 3,000m. Your first two weeks at altitude are harder than at sea level. A solid aerobic base shortens that adaptation window significantly.
Ankles and calves are locked into ski boots all day, but the surrounding muscles still work — and ankle stability is directly tied to edge control on hard snow.
The training programme
Start at least 12 weeks out. Eight weeks will still help. Two weeks will not.
Lower body — 3× per week
Squats. The single most important exercise. Start bodyweight if you haven't squatted in a while, progress to goblet squats, then barbell back squats. 4 sets × 12 reps. Go deep — the knee angle in skiing mirrors a below-parallel squat.
Wall sits. These train isometric quad endurance, which is exactly what skiing demands: not explosive power but sustained muscular contraction. Start with 30-second holds and build to 3 minutes over 8 to 12 weeks. Uncomfortable, boring, and very effective.
Single-leg squats. Start with a chair or box for support (Bulgarian split squats work too). These build balance and unilateral strength simultaneously. Each ski turn is essentially a single-leg loading event.
Romanian deadlifts. The posterior chain exercise most gym programmes neglect. 3 sets × 10 to 12 reps with moderate weight, focusing on the hamstring and glute stretch at the bottom. This is your knee insurance policy.
Lateral lunges. Skiing loads the frontal plane — lateral forces on every turn — in a way that standard forward lunges don't address. Add these and you'll notice it in the first week on snow.
Calf raises. Single-leg, on a step, with a controlled eccentric (lower slowly). 3 × 20 per leg.
Core — daily or every other day
Plank. Build to 2 minutes held. If that's easy, add a plate on your back.
Side plank. Hip stability for lateral forces in skiing. Work each side.
Dead bug. Trains core stability without spinal flexion — closer to what skiing actually demands than crunches. Start slow and controlled.
Pallof press with a resistance band. Rotational core stability. Anchor a band at chest height, press it straight out and hold. Simple, and more ski-specific than it looks.
Cardio — 2 to 3× per week
Zone 2 aerobic base. 30 to 60 minutes of steady-state running, cycling, or rowing at a conversational pace. This builds the aerobic engine for sustained effort across a full ski day.
HIIT intervals. 10 to 20-minute sessions of high-intensity effort. This matches the burst-and-recovery pattern of skiing hard — moguls, off-piste, racing a friend down a red run, then riding the lift for eight minutes.
Stair climbing with a pack. If you have access to stairs, a stadium, or a hill: load a backpack with 5 to 10kg and climb. Ski-specific cardio that also conditions the legs under load.
Balance and proprioception
Bosu ball squats. The unstable surface trains the ankle and knee stability you use constantly on variable snow surfaces.
Single-leg balance. Stand on one leg. Close your eyes to add difficulty. Build to 60 seconds per leg. This costs nothing and takes two minutes a day.
Ski simulator sessions — optional but high value. If you can access an indoor ski simulator or SkiErg in the final four to six weeks, three or four sessions will do more to convert gym strength into ski-specific movement patterns than any other single thing. The neuromuscular patterns are genuinely different from gym exercises.
What to prioritise when
12+ weeks out: Build the aerobic base. Start the strength foundation at moderate weight, focus on technique.
8 to 12 weeks out: Increase weights. Add HIIT. Focus on posterior chain — Romanian deadlifts and single-leg work.
4 to 8 weeks out: Shift emphasis to ski-specific movements. More balance work. More lateral exercises. Single-leg squats should be progressing to unsupported.
Final 2 weeks: Reduce load. Stay active but don't chase new PBs. The worst thing you can do is pull a hamstring in the gym two weeks before you fly.
The injuries most likely to ruin your season
ACL tears are the feared one. Prevention is a combination of strong, balanced quads and hamstrings (not just quad-dominant), good proprioception (hence the balance work), and controlled skiing — especially on icy or variable snow. Machismo about speed on boilerplate is how seasons end.
Knee overuse typically arrives in weeks three to four, after the adrenaline of being there wears off and the cumulative load of daily skiing becomes apparent. Strong quads delay this significantly. Don't ski through it when it starts — a rest day in week four costs you one day; ignoring it costs you three weeks.
Lower back pain comes from poor core engagement and forward-lean compensation. The dead bug and Pallof press work you've done will help. Add hip flexor stretching — skiers develop tight hip flexors, which tilts the pelvis and loads the lower back.
The single most important thing is just starting. Even eight weeks of consistent lower body training — squats, wall sits, and some cardio — will make a meaningful difference to your first weeks on snow. Don't wait for the perfect programme or the right gym. Start with bodyweight squats in your living room if that's what's available.
And before you fly: get travel insurance that actually covers skiing, including off-piste. Check the wording. Some policies exclude off-piste unless you're with a guide. You will ski off-piste. Make sure you're covered.
