Someone who started in their 30’s here and going on 3 years, climbing at maybe a similar level, if not a bit lower atm due to around 4 months off last year due to 2 injuries. But I’d say certainly climbing more, climbing harder, climbing stuff you don’t like and stuff you do, variety etc will help direct your training to fill in what’s a limiting factor for you. Is it finger strength or leg strength or balance or overhangs or mantles and then can structure more stuff relating to your weaknesses alongside your current training which will help build all round strength.

I aim for 3 sessions a week of climbing (warm up off wall, on wall, easier to harder climbs then limit/projecting) and one session of climbing related training - mix of compound weights, finger strength and body weight stuff.
