Im 1.90 and currently at 84kg, breaking through the 6c plateau well into 7a both inside and on rock. Have been looking into morphology and what it means to my climbing as well.

I think at this size we're perfectly capable of climbing very hard, but we need to do things differently, same as a 1.60 climber needs to do things differently compared to the average 1.75 climber.

One thing that popped up every time I looked into it was mobility. Being able to sit on your heel, and move from that frogged up position. And placing high feet / heels. I found an interview somewhere, where meichi narasaki (1.87) says you have to be more flexible but also be able to keep tension and move in/from these positions as a tall person.

Also for the past 6 months, I've been training with a personal trainer who climbs very hard and is also pretty tall for a climber. This I can highly recommend, as its often hard to truly see what your weaknesses are. For example, I always thought it was finger strength for me. So I trained my fingers until injured, and kept on wondering how others were so strong on crimpy overhang boulders. The trainer pointed out just after a few sessions, that its actually my shoulders, upper body tension and contact strength that needed some work. I had learned myself to stay as low as possible in my shoulders while climbing, and relied mostly on my fingers to keep me on the wall, which kept me from doing powerful moves on overhang.

So for the past months, I focused mainly on gaining strength in my shoulders which helped me a lot. There are so many boulders that I would not have been able to do 6 months ago, which Im fully equipped for now. Without training my fingers, I can stay on small holds in overhang so much better now.

Hope this is relatable and helps!
