A knee bar is a resting and locking technique where you wedge your leg between two opposing surfaces — jamming the knee or thigh against one and the foot against the other — so the leg supports your weight and frees your hands. A good knee bar can offer a precious no-hands rest on steep terrain.
How it works
The leg locks between a foothold and an overhanging feature, bearing weight so your arms can recover from the pump — invaluable on overhangs and roofs.
Finding one
Scope for gaps matching your shin length; sticky knee pads help. Related steep-wall moves include the drop knee and heel hook.
Frequently asked questions
What is a knee bar?
A knee bar is when you jam your leg between two surfaces — pressing the top of your knee or thigh against one feature and your foot against another — so the leg locks in and bears your weight. It can range from a helpful bit of support to a complete no-hands rest.
How do you find a knee bar?
Look for a gap, roof, or corner where the distance between a foothold and an overhanging feature roughly matches your shin length. Knee bars are easy to miss, so scoping a route for them — and many climbers use sticky knee pads to improve grip — is part of the game.
Can you rest hands-free on a knee bar?
Yes — a solid knee bar can take all your weight, letting you take both hands off to shake out, chalk up, or clip. Finding a good no-hands knee bar at the right spot can be the key to sending a steep route.
