I went bouldering twice this week, and I'm definitely improving! I just touched the top of this problem (V1?) I've been working on for the last week (and then fell ingloriously to the floor, tearing a flapper in the process), so I think next time I'll be able to grab the top no problem. I'm starting to feel more confident on the walls, which I think is a great help. I can now also do a good few negative pull-ups at home on the bar, so maybe one day I'll even be able to do a proper pull-up. I know it's not all about strength, but I think it also helps with the confidence.
