Ask a slalom skier what hurts after the first warm weekend of the season: forearms that won’t open a water bottle, a lower back that complains in the car, hamstrings that feel every deep-water start. Water skiing looks like the boat does the work. It doesn’t. You hold a handle against the pull of an engine, lean against it through every turn, and absorb chop, wakes and, if you jump, a landing far down the course. This page is about water ski training: the strength, grip, core and balance work that helps you ski longer, run more buoys and get hurt less, from kids on combo skis to college teams, tournament skiers, show skiers and barefooters.

General information, not a personal program. If you’re coming back from an injury, have pain or a health condition, work with a physical therapist (PT), certified athletic trainer (AT) or strength coach. Back to the water skiing hub.

What water skiing asks of your body

  • Pulling strength from the first second. A study that measured takeoff forces found a deep-water start loads the arms with roughly one and a half times body weight.
  • Slalom: a hard lean and a load through the legs, back and grip on every one of the six buoys, pass after pass as the boat speeds up and the rope gets shorter.
  • Tricks: two 20-second passes of spins, wake flips and, for advanced skiers, toe-hold tricks with the handle on a foot strap. Balance, rotation and quick feet.
  • Jump: a hard cut to the ramp, then a landing well down the course. A review of tournament skiing found a surprisingly high rate of lower-back injuries in this event.

Research on water skiers is thin, but one small study helps. Researchers who tested 20 college water skiers found that different qualities went with success in each event: body build with slalom, grip strength with the trick event’s hands pass, and trunk muscle endurance with the jump. A survey of 96 college skiers found 43% had chronic trunk pain, and its authors called for a systematic core-strength program. That gives a clear plan: legs, posterior chain, core, grip and balance, built up gradually. The injuries themselves are on our injuries page.

Legs and hamstrings

Strong legs hold the stacked, knees-bent stance through the wakes and absorb chop instead of passing the shock to knee ligaments. Water skiing is also one of the sports the American Academy of Orthopaedic Surgeons names for hamstring injuries, so the back of the thigh deserves its own work. In team sports, programs that mix strength, landing practice and balance cut ACL injuries by about half in a large review; skiers can use the same ingredients two or three times a week on land:

  • Squats and split squats for the bent-knee stance.
  • Romanian deadlifts, bridges and hamstring curls (including slow “Nordic” lowers when you’re ready) for the hamstrings and hips.
  • Landing drills for jumpers: small hops and box jump-downs with soft, bent knees, building height over weeks.
  • Calf raises and single-leg work for ankles that live in bindings.

Core and back

Your trunk links the handle to the ski. When it tires in slalom, you get pulled forward out of position at the ball and the next turn is late; in jump, the back takes the landing. Train it to resist bending and twisting, not just to crunch:

  • Planks and side planks, 30 to 60 seconds, a few rounds.
  • Back extensions and bird dogs for the muscles along the spine (trunk endurance was the quality tied to jump results in the college study).
  • Pallof presses and cable or band rotations for controlled rotation, useful for trick skiers.
  • Young jumpers: the tournament review warns the growing spine may be damaged by overuse, so keep jump volume modest and progress with a coach.

Grip, forearms and shoulders

Tired forearms end more slalom sets than tired legs. In a case study of a seated (adaptive) slalom skier, handgrip strength dropped clearly after a session of deep-water starts, which matches what every skier feels. Train grip and the upper back, and learn to save them on the water:

  • Dead hangs, farmer’s carries and towel rows for grip that lasts.
  • Finger and forearm work with a hand trainer such as the Prohands Gripmaster, plus wrist extensions to balance the forearm.
  • Rows, pull-ups and band pull-aparts for the back and shoulders that hold the lean.
  • On the water: handle low and close to the hips, arms long, let the body lean and legs hold the load instead of bending the elbows. And let go when a fall starts.

Balance

Balance work trains ankles and knees to react, and the National Athletic Trainers’ Association recommends at least three months of balance training after an ankle sprain. Start on one leg on the floor, then on a cushion, then on a roller board such as the Indo Board (stand next to a wall at first). Slalom skiers can practice their stance with the front foot forward; trick skiers and barefooters benefit from both directions. Balance work is an extra, not a substitute for strength.

Warm up on the dock

Most skiers go from a car seat straight to a deep-water start, which is a lot to ask of a cold hamstring and a cold back. Five to ten minutes changes that: leg swings, walking lunges, bodyweight squats, hip hinges, arm circles, band pull-aparts and a few trunk rotations. Make the first pass of the day an easy one at a slower speed or a longer rope before you go to your shortest line. A few minutes on a foam roller the night before or after the session suits people who like it.

Training on the water

  • Quality over quantity. A few focused slalom sets with rest beat an hour of sloppy passes. Stop when grip or legs fade.
  • Progress one thing at a time: speed first, then rope length, the same order the tournament scoring follows.
  • Video helps. A friend filming from the boat (never the spotter) or from the shore shows what your body is doing at the ball. See our best wearables page.
  • Get coaching. Ski schools and clubs teach progressions for slalom, tricks and jump; USA Water Ski & Wake Sports clubs are listed on our leagues and associations page.

The off-season

In much of the country the lakes are cold for months. That’s the time to get strong.

  • Strength two or three times a week: legs, hamstrings, back, core, pulling and grip.
  • Conditioning: cycling, rowing, swimming or running two times a week to keep your engine up for long tournament days.
  • Fix what hurts. Off-season is when to work with a PT on a nagging back, knee or shoulder.
  • Ease back in. First weeks back on the water: easier speeds and longer lines, then shorten as your grip and back adapt. Snow skiing and other board sports are fun cross-training, but count them as training load.

A sample week

A practical example, not a prescription. In season: ski 2 to 4 days, one or two short strength sessions (legs, hamstrings, core, grip) on non-skiing days, balance work at home, and at least one full rest day. Off-season: 2 to 3 strength sessions, 2 conditioning sessions, balance work 2 to 3 times a week, and rest. For kids and teens, the American Academy of Pediatrics recommends at least one to two days off a week from organized sport and time away from a single sport across the year.

Water ski training: FAQs

What muscles does water skiing use?

Nearly all of them: legs to hold the bent-knee stance and absorb chop, hamstrings and back to resist the pull, core to stay stacked through slalom turns and jump landings, and shoulders, forearms and grip to hold the handle through every start and turn.

How do I stop my forearms from burning out in slalom?

Part technique, part training. Keep the handle low and close with long arms and let your lean and legs carry the load. Off the water, train grip with dead hangs, farmer’s carries, towel rows and finger work. If forearm pain lingers between sessions, see a PT or athletic trainer.

How can water skiers protect their lower back?

Build trunk endurance with planks, side planks, back extensions and anti-rotation work, strengthen the hips and hamstrings, warm up before the first pass, and progress jump speed and distance slowly with a coach. Researchers who found high rates of chronic trunk pain in college skiers recommended exactly this kind of core program.

Is a balance board good training for water skiing?

It’s a useful, fun extra for ankles, stance and reactions. Start next to a wall and progress slowly, and keep doing strength work: a balance board doesn’t build the legs, back and grip that skiing needs.

How should I train in the water ski off-season?

Strength two or three times a week (legs, hamstrings, back, core, pulling, grip), some cardio, balance work, and rehab for anything that nagged during the season. Then ease back in with slower speeds and longer lines in spring.
