Bouldering

This might sound like throw away advice, but really it's simple: find people who are better at it than you are, hang out with them, and practice as often as you can. Then practice more. And when you feel like you have practiced enough, do it again.

Not bouldering, but on my bike I went from "yeah, I can sort of do jumps" to sending the biggest shit I can find in just under 2 years and all I did was exactly what I just said. The people I know who keep levelling up are the ones who do three times as many reps as anyone else.

At the trails, there are the people who sit around, chit chat, and occasionally send a lap, and then there are the people who just go non stop. For every lap everyone else is doing, they knock out 3. It's true for every sport. There is no shortcut to greatness. It's a grind. A rewarding grind, but a grind nonetheless.

Watching YouTube videos on technique and professional competitions can help a lot.

I think a good goal is knowing your V rating level and being able to top all of those problems in the gym/outside. So, if you feel good about v2s, complete every available V2 cleanly before moving to a V3.

I feel like the biggest thing for me is trying climbs higher than what I can actually complete. The goal for me isn't always sending a problem but sometimes just doing a hard/cool move and learning from it.

Along with this going at the wall with intention is useful. Start every climb with reading beta, and not just where your hands go but feet and body positioning as well. When falling off a wall don't just go back on right away, figure out why you fell off and come up with a plan for your next attempt.

You probably don't need to do any lifting, fingerboarding or anything of that nature this soon in; climbing is probably the route to quickest improvement.

Don't feel like you need to incorporate all the advice you get at once, just pick through and focus at one point at a time until it's habit.
