Unsure! How tall are you?Would my weight be a struggle, do you think? I'm certainly fit in a general sense, but I know climbing is something else entirely. I'm like, 95kg usually and I can do pullups with ease, but not sure that would transfer well to actually climbing a wall. I assumed I'd have to lose weight and drop my overall strength to actually do it.
You’ll be totally fine. Unless you want to be a world class climber, you can get up some very challenging, engaging, and/or just plain fun stuff at a gym and outside with your build. Strength will be really helpful but it’s a lot of technique, flexibility, and muscles that you don’t use in a lot of other scenarios.
I'm no climbing expert, but i've once seen a beginner (as in never climbed in her life) lady absolutely brute force up a wall and leave all other beginners in the dust - looking like an absolute beast stuck to the wall all muscles engaged the whole way. It was impressive. Climbing is lots of technique actually so while strength and flexibility are a factor, i feel anyone generally fit can get a start. The easier routes are almost just going up a ladder type exercises.
