| Technique | Outward pressure on two surfaces |
| Best in | Corners (dihedrals), chimneys |
| Can be | Strenuous or a rest |
| Difficulty | Intermediate |
Stemming, also called bridging, is a technique where you press outward with opposing limbs against two surfaces — typically the two walls of a corner or chimney — using counter-pressure to stay in place without positive holds. It can be strenuous or restful, and lets climbers ascend dihedrals and wide features with little to grip.
How it works
Push a hand or foot against each surface so the opposing pressure holds you — like bracing in a doorway — then move up by shifting the pressure points.
Where to use it
In dihedrals and chimneys; a wide bridge often gives a welcome rest.
Frequently asked questions
What is stemming in climbing?
Stemming is using counter-pressure between two opposing surfaces — pushing a hand or foot against each — to hold your position and move up without needing positive holds. It turns a corner or chimney into something you can press your way up, like bracing in a doorway.
Where do you stem?
In dihedrals (inside corners) and chimneys, and anywhere two surfaces face each other closely enough to push between. It's the defining technique for climbing corners, which often have a crack but few face holds.
Is stemming restful?
It can be — bridging wide between two walls lets you take weight off your arms and shake out, making good stems some of the best rests on a route. But narrow or strenuous stems that keep your legs flexed can be tiring instead.
