How to mantle on boulders, and the drills that make it easy

Short answer

Pull until the edge is at your chest. Turn one hand so the palm presses down, fingers pointing sideways, get your elbow over it and press until the arm is straight. Then bring a foot up next to that hand early, rock your hips over it and stand up with your leg. Belly-flops happen when you press with both arms and leave your feet down. Practise 4 or 5 low mantles, 3 to 5 tries each, once a week, and add L-sits or dips to the strength part of a session if the press is what fails.

"Why are mantles so hard?"

A mantle is getting onto a ledge or the top of a boulder by pushing down on it, like climbing out of a swimming pool. Everything else on an indoor boulder is pulling, so most climbers have done hours of pulling and almost no pressing. Then the top-out arrives, high up and at the end of the problem, and both the move and the muscles are new.

Most of it is technique, though, and you can practise that close to the ground.

Step by step

Pull until the edge is at chest height. Higher is easier to press from.
Turn one hand so the palm is flat on the top, fingers pointing sideways or back towards you.
Get that elbow over the hand and press until the arm is straight. Keep your chest close to the rock.
Bring a foot up beside that hand. On a sloping top, a heel hook on the lip first can take weight off your arms.
Rock your hips over the foot, keeping your weight low and close.
Stand up with your leg, walking your hands in or pressing with the other one.

Going with the heel first or the press first depends on the top. A good edge to hook favours the heel. A small lip or a flat top favours pressing first.

Practise it low

Mantle practice uses ledges, volumes or big holds close to the floor, 4 or 5 different ones, so you can try a move ten times without fear of the top. Then finish real boulders with a top-out instead of jumping off from the last hold.

Rock-over repeats train the second half: getting your weight over a high foot and standing up with your leg. If the high foot is where it fails, high-step stretches on the wall give you the range.

The strength behind it

Two or three times a week, a few minutes after climbing:

L-sits. Pushing down through straight arms with your legs up, the same press a mantle ends with.
Dips, or bench dips if full ones are too hard. They also balance out all the pulling.
Push-up plus for the shoulder blades, which have to stay flat on your ribs while you press.

Where it goes wrong

Belly-flopping. Pressing with both arms and lying on the top with your legs hanging. Get a foot up early.
Pressing with your fingers pointing forward. The wrist bends back too far and the press is weak.
Looking for a hold over the top that isn't there, while your arms tire.
Only meeting mantles at the top of a tall boulder when you're already pumped. Practise them where falling off doesn't matter.

Who this isn't for

If your gym has no top-outs, you still meet mantles on volumes and big ledges, and the drills work there. If your wrist or shoulder hurts when you press, leave this out and see a physio.

The exercises

Mantle practice

4-5 different mantles low to the ground, 3-5 tries each.

Questions

Should I use my knee to mantle?

A knee on the lip feels secure, and sometimes it's the only way. Standing up from a kneel is harder than standing up from your foot, though, and it hurts on a sharp top. Try for the foot first.

How do I get stronger at mantling?

Mantle more, low to the ground, so the technique stops costing strength. For the press itself, dips and L-sits train pushing down through straight arms, which climbing alone barely does.

Why does mantling hurt my wrist?

Pressing with the wrist bent far back puts a lot of load on it. Turn the fingers out to the side or back towards you and press through the heel of your hand. If it still hurts, stop, and see a physio if the pain stays.

Do I need to be flexible to mantle?

You need to get a foot up next to your hand, which takes some hip range. If your foot can't get there, the high-step stretch on the wall and the hip mobility routine on this site help.
