I’m not an expert but I’ve been climbing regularly for 4ish years and started bouldering about 3 years ago…I’m a huge fan, I think it has helped my technique immensely in a way that I haven’t found climbing on the ropes, especially indoors.
Sure it’s great for strength, but if you are challenging yourself bouldering will force you to break down into fine detail movements and body positions, and be more creative with how you move – this is how I think it’s been hugely beneficial to me, especially as someone who is newer to climbing and doing moderate grades.
It will also help with your overhang technique/confidence if you do some steep boulders, which will help a ton as you progress your grades. I find I’m sometimes too pumped roped up on the wall to think much about my technique. If you practice this bouldering better technique will start to come naturally.
I wasn’t able to do any of the boulders on my gym’s (steep) bouldering wall when I started but I persisted and am seeing huge benefits now…It won’t help your headspace with lead climbing so much, or your aerobic capacity(if that’s the right word), but it will make you move better and help with technique and strength.
If I were you I’d go crazy autobelaying 4-6h a week and would definitely mix in at least one solid bouldering session during the week, or more depending on how intense/long they are.
Just saw this realize this is a super late response!
