First warm, then heavy: A good warm-up doesn't start at the wall.

Shoes on, chalk on hands, and straight into the project boulder – that's how many start their session. But that's... Warming up while bouldering One of the simplest ways to prevent injuries and improve your climbing. This guide shows how long the warm-up should last, which phases are beneficial, and what comes after the session.

The most important points in brief
  • Duration: According to Bergzeit, 15 to 25 minutes is recommended.
  • Three phases: Cardiovascular system, joints, then easy bouldering on large holds.
  • Stretch: Stretch briefly beforehand (approx. 8 seconds), then stretch for a longer time afterwards.
  • Finger: Increase the load slowly before moving on to the smaller holds.
  • Head: Warming up also prepares you mentally for the session.

Why warming up is important

According to Bergzeit magazine, warming up prevents injuries because warmed-up muscles are more supple. This also leads to improved performance, less muscle soreness, and better mental preparation. The outdoor magazine presents a warm-up program developed by trainer Dr. Tyler Nelson, which he claims halves the risk of injury – comparable to warm-up programs used in soccer.

The three phases

  1. Cardiovascular system: Cycling, skipping rope or jumping jacks with push-ups – the body gets warmed up.
  2. Joints: Move all joints briefly, from top to bottom or vice versa: fingers, wrists, shoulders, hips, knees, ankles.
  3. On the wall: Climb easy boulder problems using large holds and take a break as soon as your forearms get tired.

Practical tip from Raul

When warming up on the wall, don't just climb jugs, but gradually incorporate the different holds of the session: first large holds, then slopers and pinches, and finally smaller crimps. This way, your fingers are ready before things get serious.

Stretching: before or after?

According to Bergzeit, only a short [break/break/etc.] is required before bouldering. Stretching for about 8 seconds It makes sense. Longer stretches (over 20 seconds) and passive stretching should be done after the session. Bergzeit suggests using putty or a soft ball for the fingers and a resistance band for the shoulders.
