Your ski trip starts in the gym, not on the slopes
You've booked the chalet, dug out the salopettes and checked the snow reports twice. But have you trained your legs?
Most people spend 50 weeks of the year sitting at a desk, then ask their body to ski for six hours a day, at altitude, for a week straight. The result is predictable. Burning thighs by lunchtime on day one, wobbly legs by day three, and the tired, sloppy turns that cause most falls.
The good news is that eight weeks of focused training makes a huge difference. This guide walks you through what skiing actually asks of your body, a week-by-week pre-ski plan, and the exercises that matter most for protecting your knees.
What skiing actually demands of your body
Skiing looks like a leg sport, and it mostly is. But it tests your body in a few specific ways that ordinary gym routines often miss.
Isometric leg endurance. Holding a flexed-knee stance for minutes at a time puts constant load on your quads and glutes. This is why your thighs burn even on gentle runs.
Eccentric strength. Every turn involves absorbing force as your legs bend under you. Muscles that are strong while lengthening control speed and protect joints.
Single-leg stability. In a turn, most of your weight sits on the outside ski. Strong, stable single-leg control keeps your knee tracking safely over your foot.
Core and rotational control. Your upper body stays quiet and facing downhill while your legs turn underneath. That needs a strong, responsive trunk.
Repeated-effort fitness. A long red run is effectively an interval session. Better conditioning means you finish the day with good technique, not just survive it.
Hip and ankle mobility. Stiff hips and ankles push you into the 'back seat', which loads the knees and makes the skis harder to steer.
A good pre-ski programme trains all six, not just squats.
The 8-week pre-ski training plan
The plan runs in three phases. Train three times a week, with at least one rest day between sessions. If your trip is sooner than eight weeks away, start at the phase that matches your current fitness and compress the rest.
Phase 1: Foundation (weeks 1–3). Build a strength base, mobility and good movement patterns. 3 sets of 8–12 reps, slow and controlled.
Phase 2: Strength and control (weeks 4–6). Heavier loads, single-leg work and eccentric control. 3–4 sets of 6–10 reps with a 3-second lowering phase.
Phase 3: Power and endurance (weeks 7–8). Jumps, ski-specific intervals and leg stamina, using circuits and timed intervals.
Phase 1: Foundation (weeks 1–3)
Build the base. Focus on technique before you add weight.
Goblet squat – 3 x 10. Sit between your heels, chest up, knees tracking over toes.
Romanian deadlift – 3 x 10. Hinge from the hips to load the hamstrings, which help protect the ACL.
Split squat – 3 x 8 each leg. Your first step towards single-leg strength.
Glute bridge – 3 x 12. Strong glutes keep your knees from collapsing inwards.
Wall sit – 3 x 30–45 seconds. Your first taste of ski-stance endurance.
Dead bug – 3 x 8 each side. Core control without straining your lower back.
Ankle and hip mobility – 5 minutes of knee-to-wall ankle stretches and 90/90 hip switches.
Phase 2: Strength and control (weeks 4–6)
Add load, slow the lowering phase and put more work on one leg at a time.
Back or front squat – 4 x 6–8, lowering for 3 seconds.
Rear-foot elevated split squat – 3 x 8 each leg. The single most useful ski exercise in this plan.
Single-leg Romanian deadlift – 3 x 8 each leg. Builds balance and hamstring strength together.
Lateral lunge – 3 x 8 each side. Trains the side-to-side movement of turning.
Copenhagen plank – 3 x 15–20 seconds each side. Strengthens the inner thighs, which work hard when holding an edge.
Pallof press – 3 x 10 each side. Anti-rotation core strength for a quiet upper body.
Wall sit – 3 x 60–90 seconds.
Phase 3: Power and endurance (weeks 7–8)
Now make the strength usable at speed and over a full day on the hill.
Lateral skater bounds – 3 x 10 each side. Land softly and hold each landing for a second.
Box jumps or squat jumps – 3 x 6. Focus on quiet, controlled landings with knees over toes.
Ski-stance circuit – 4 rounds of 45 seconds work, 15 seconds rest: wall sit, lateral hops over a line, split squat jumps, plank.
Rear-foot elevated split squat – 3 x 8 each leg. Keep strength ticking over.
Conditioning intervals – 2–3 times a week, 8 x 40 seconds hard on a bike or rower, 80 seconds easy.
In the final four or five days before you travel, drop the volume. Arrive with fresh legs, not sore ones.
How to protect your knees when skiing
Knee injuries, especially to the ACL and MCL, are among the most common ski injuries. You can't remove the risk entirely, but you can stack the odds in your favour.
Train your hamstrings, not just your quads. Hamstrings help stop the shin sliding forward, which takes strain off the ACL. Romanian deadlifts and Nordic curls are excellent here.
Fix knee collapse. If your knee caves inwards during a squat or lunge, your glutes and hips need work. Film yourself from the front and check.
Practise landing. Soft, controlled landings in phase 3 teach your knees to absorb force safely.
Stay out of the back seat. Tired legs make you sit back, which overloads the knees. Better endurance keeps you centred on your skis.
Know when to stop. A lot of injuries happen on the last run of the day. If your legs feel shaky, call it.
Get your bindings set properly. Make sure the shop sets your DIN settings from your accurate weight, height, age and ability.
If you have a previous knee injury, speak to a physio or an experienced trainer before starting the plyometric work in phase 3.
5 common pre-ski training mistakes
Starting two weeks before you fly. Strength takes time to build. Cramming hard sessions just before your trip leaves you sore and tired on the slopes.
Only doing cardio. Running builds your engine but won't prepare your legs for the sustained, heavy load of skiing.
Skipping single-leg work. Squats with both feet are useful, but skiing is mostly a one-leg-at-a-time sport.
Ignoring mobility. Tight ankles and hips limit your stance and push you backwards. Five minutes a session is enough.
Training hard right up to departure. Taper in the final week so your legs are fresh for day one.
Ski fitness FAQs
How long before a ski trip should I start training?
Ideally eight weeks. That's enough time to build real strength and endurance. Even four weeks of consistent training will make a noticeable difference.
What is the best single exercise for skiing?
The rear-foot elevated split squat. It builds single-leg strength, balance and hip control together, which covers most of what skiing demands.
Can I get fit for skiing at home?
Yes. Wall sits, split squats, lateral lunges, single-leg deadlifts, glute bridges and lateral bounds need little or no equipment. A pair of dumbbells or a kettlebell lets you keep adding load.
Why do my thighs burn so much when I ski?
Your quads hold a bent-knee position for long periods, which restricts blood flow and builds fatigue quickly. Sitting back on your skis makes it worse. Wall sits and better technique both help.
Should beginners train differently?
Beginners should follow phases 1 and 2 and add the phase 3 circuits only if they feel confident with landings. Beginner skiing still involves lots of time in a snowplough stance, which is tiring on the legs.
Do I need a personal trainer for ski fitness?
Not necessarily, but a trainer can check your technique, spot knee collapse and adjust the plan to your trip date, ability and injury history.
Ready to hit the slopes stronger?
The skiers who enjoy their trip most are rarely the most talented. They're the ones whose legs still feel good on day five. Eight weeks of focused strength, stability and conditioning work can give you more runs, better turns and a lower risk of injury.
