Late September. The leaves are turning, the first early-season snow shows up on the resort webcam, and somewhere a skier is doing wall sits in the kitchen while the coffee brews, thighs shaking at the 45-second mark. That’s ski training: the weeks before the season that decide whether your first day ends with legs that still work at 2 p.m., or with a long, careful snowplow back to the lodge. This page covers pre-season ski fitness for every level, from kids heading into their first ski-team winter and high school racers to college and World Cup athletes and the adult who skis ten days a year: leg strength, balance, plyometrics, cardio and the warm-up on the hill.

General information, not a personal training plan. If you’re coming back from an injury, are new to exercise or have a heart or joint condition, check with a sports medicine doctor, physical therapist or athletic trainer first. Back to the skiing hub.

What skiing asks of your body

Downhill skiing is real exercise. The Compendium of Physical Activities, the reference researchers use to rate effort, puts alpine skiing at 4.3 METs (multiples of resting energy) for light effort, 6.3 for moderate and 8.0 for vigorous skiing, counting only the time you’re actually moving. Racing is harder still: in a study of well-trained racers around age 18, giant slalom runs drew a bit under half their energy from the aerobic system, with the rest from short, high-power energy systems. In practice that means a ski body needs:

• Strong thighs and hips that can hold a flexed position turn after turn and absorb bumps and landings.
• Balance and quick reactions on each leg, because every turn loads the outside ski.
• An aerobic base to last the day, and repeat the day on a ski trip.
• A strong trunk to keep the upper body quiet while the legs work.

An honest word on fitness and injuries

The American Academy of Orthopaedic Surgeons (AAOS) advises being in good shape before you ski, warming up and stopping when you’re tired. That’s sound advice. But ski-safety researchers Johnson, Ettlinger and Shealy reviewed the evidence and found no convincing proof that general conditioning lowers the risk of ski injuries on its own; strong thighs haven’t kept even Olympic skiers’ ACLs safe. Where they see conditioning paying off is endurance and enjoyment. Two things do have ski-specific evidence for the knee:

• Knowing how ACL injuries happen. Ski patrollers and instructors who watched video training on the classic ACL situations had 62% fewer serious knee sprains than in earlier seasons. Our skiing injuries page explains those positions.
• Neuromuscular training for young racers. Swedish ski high schools that added an ACL program built on core stability, balance and control, practiced equally on both legs, saw ACL injuries fall from 8.1% of students to 3.9%. Across many sports, a summary of meta-analyses found jump, landing and strength programs halve ACL injuries.

So train for the skiing you want to do, include landing and balance work, and don’t expect fitness to make up for badly set bindings or skiing out of control.

A pre-season plan: 6 to 8 weeks out

The baseline for any adult comes from the U.S. Physical Activity Guidelines: 150 to 300 minutes of moderate aerobic activity a week, plus muscle-strengthening on at least two days. A simple ski block on top of that, two or three sessions a week:

1. Leg strength

• Squats and wall sits for the flexed “ski stance”. Build from 30 to 60+ second holds.
• Split squats, lunges and step-downs: one leg at a time, knee tracking over the toes, slow on the way down.
• Romanian deadlifts and hip bridges for hamstrings and glutes, the muscles that help hold the knee.
• Lateral band walks with a mini loop band around the knees or ankles, for the hip muscles that steer the knee.

2. Balance

Stand on one leg while you brush your teeth, then progress: eyes closed, on a foam balance pad, with a slight knee bend, catching a ball. Single-leg squats to a box and holding a “skier’s tuck” on an unstable surface turn balance into strength. Do both sides equally, the way the Swedish program did.

3. Plyometrics and lateral power

Skiing is side-to-side. Skater hops (bound sideways from one leg to the other and stick the landing), lateral line hops, low box jumps and tuck jumps build quick, springy legs. Quality beats quantity: land softly, knees bent and in line with your toes, never collapsing inward, the same landing rules used in ACL prevention programs. A slide board is a classic ski and skating drill for lateral endurance. Start plyos twice a week with short sets and full rest; stop when landings get sloppy.

4. Cardio and core

Hiking with hills, cycling, rowing and running all build the base for long days; add intervals of 1–3 minutes hard with equal easy time to mimic a long run down. For the trunk: planks, side planks, dead bugs and anti-rotation band presses. If your ski trip is at a high resort, remember altitude will make everything feel harder for the first couple of days.

Equipment for dryland training

You can do most of this with body weight, but three inexpensive tools make ski-specific work easier at home: a slide board such as the SPRI Slide Board (71 x 20 inches, with booties), a foam pad like the Airex Balance Pad Elite, and a set of mini bands like the Fit Simplify loop bands. More choices in our resistance bands for athletes guide and the speed training equipment guide.

Warm-up on the mountain

AAOS suggests 3 to 5 minutes of jumping jacks, jogging or walking in place before you ski. Add a few leg swings, squats and lunges in your boots at the base, then make the first run an easy groomer with relaxed, round turns. On cold mornings, layer up so the warm-up isn’t undone on the first chair ride. And use the AAOS rule for the end of the day too: when you’re tired or something hurts, stop.

Training by level

• Kids: play-based movement (tag, balance games, jumping, biking) beats formal workouts. The American Academy of Pediatrics recommends at least 1–2 days off a week from organized sport and time away from a single sport each year. See youth skiing.
• High school and club racers: dryland in the fall with a coach, ACL-prevention work all year, and equal training on both legs.
• College and elite racers: periodized strength and power programs with team strength coaches and sports medicine staff; recovery and sleep become part of training (see ski recovery).
• Adults and older skiers: the CDC recommends balance activities for older adults alongside strength and aerobic work. Two strength sessions plus daily balance practice is a strong pre-season for any 50+ skier.

Ski training: FAQs

How long before ski season should I start training?

Six to eight weeks of two or three focused sessions a week makes a noticeable difference, especially for leg endurance. If you’re starting from little exercise, give yourself longer and build gradually.

What are the best exercises for skiing?

Squats and wall sits, single-leg work like split squats and step-downs, hamstring and glute exercises, lateral skater hops, balance on one leg, and core work such as side planks. Cardio intervals cover the endurance side.

Does getting fit prevent ski injuries?

Fitness helps you ski longer with better control, but ski-safety research hasn’t shown that general conditioning alone prevents injuries. Well-set bindings, skiing in control, knowing the ACL danger positions and, for young racers, neuromuscular programs have the best evidence.

Are plyometrics safe for older skiers?

Often, in a scaled form: low hops, small lateral steps, soft landings, few reps. If you have joint problems, osteoporosis or a past knee injury, ask a physical therapist which versions fit you.

Is a slide board worth it for skiers?

For many skiers, yes. It trains the side-to-side push and hip control skiing uses, it’s low impact, and it rolls up for storage. It’s a training tool, not a must; skater hops on the floor do similar work.
