Lee McCormick unlocked steep MTB climbs for me. I’ll talk about it on the podcast in detail.
Short answer:
- stand almost straight up with hips next to bars
- pull back with both hands at once (this was the key for me). It levers your rear wheel into the ground for traction.
- you sort of “hump the bars” with each pedal stroke and pull back.
I haven’t tried it in a road bike yet but I was able to climb stuff that I’ve never thought I’d be able to climb with this technique.
It would be really hard to do for a long climb. Works well for loose MTB steep pitches.
