I started bouldering late last year and have plateaued at around a V4 level. I feel like my biggest weakness by far is my finger strength, so I’m thinking of starting hangboarding to work on that.
I’m not sure where to start though, I feel like I already tax my fingers when climbing so I don’t want to go overboard and injure myself.
A little clarity to add is once you can climb V4 consistently then you could start worrying about things like actually incorporating hamgboarding but the sub max training you could start doing very early.
