In reply to Effy_yeomans:
Whenever I get back into bouldering after concentrating on sport, my knees hurt for a bit. I tend to try and downclimb where possible, and only jump down if I'm falling.
I think it's common sense that if you jump from 10 feet up, over and over again, for hours and hours a week, your knees are gunna tell you to go do one.
And look at how many pros have knee surgery, or knee problems. Shauna is constantly have surgery on them, and she's not alone.
I think indoor bouldering needs to normalise a kind of drop and roll action when jumping down or falling. Sticking the landing, is awful for your knees. Doing a paratrooper type landing, and rolling onto your back, distributes the energy from the fall.
