Cross-training for hiking: what actually carries over to the trail

Cycling, swimming, rowing, the cross-trainer. They all build fitness, but not all fitness carries over to a trek. Here's what's worth your time, and what isn't.

The short answer: Cross-training is great for building your engine, adding volume without the pounding, and training through niggles or bad weather. But it can't replace hill walking with a pack. Keep your long walk and strength sessions, and use cross-training on top or instead of an easy session.
01 / When it helps

Four good reasons to cross-train

  • Bigger engine, less pounding

    Cycling or rowing add aerobic work without the impact of more walking, useful for heavier bodies and tired joints.

  • Training through a niggle

    A sore foot or knee might rule out walking but not the bike or the pool. You keep your fitness while it settles.

  • Weather and dark evenings

    Indoors and warm beats skipping a session altogether.

  • Keeping it fresh

    Variety keeps training enjoyable, and enjoyable training is the training you actually do.

02 / What carries over

How each option compares for trekking

  • Hill walking with a pack
    The real thing. Nothing beats it.
  • Incline treadmill or stair machine
    Climbing legs and engine. No descents.
  • Cycling
    Big engine and thighs, low impact. No walking or descents.
  • Elliptical (cross-trainer)
    Low-impact engine work with a walking-like motion.
  • Running
    Big engine, but high impact and no pack or climbing legs.
  • Rowing
    Engine plus back and hips. Little leg specificity.
  • Swimming
    Great for heart, lungs and recovery. Least specific.
The one rule. Cross-training builds the engine. Hiking builds the hiker. Keep your long walk, your hills and your strength work, and let cross-training fill the gaps.
03 / How to use it

Fitting it into your week

  • Swap an easy walk for an easy cross-training session when your legs need a break from impact.
  • Keep the effort mostly easy, the same talk test as your walking.
  • Never let it replace your long walk or your strength sessions in the last two months before a trek.
  • If you're injured, ask a physio which options are safe for you before you start.
Questions

Questions people ask

Is cycling good training for hiking?

Cycling builds your aerobic engine and your thighs with very little impact, so it's a useful extra. It doesn't train walking uphill with a pack or descending, so keep hiking-specific sessions too.

Is swimming good for hiking fitness?

Swimming is great for your heart and lungs and for recovery, but it carries over the least to trekking because your legs don't bear weight. Use it as an extra, not a replacement.

What's the best cross-training for hiking?

Incline walking and stair machines carry over the most, then cycling and the elliptical. Rowing and swimming build the engine but are less specific.

Can I train for a trek if I can't walk much because of an injury?

Often yes: cycling, swimming or the elliptical can keep your fitness while you recover. Get advice from a physio on what's safe, and build walking back in gradually once you can.
