In reply to Andy Morley:
> For example, I'm doing body-weight squats which my martial-arts son also does as part of his routine, but I also do them with barbels, like they do down the gym. That helps strengthen my legs which can get neglected over the winter as I cycle less and climb indoors more, but it's also good for balance and core. Planks are good for core too. Apart from yoga, does your wider training cover finger, arm and shoulder exercise too?
I do a fair amount of various "regular" training: fingerboard, classic weight exercises and planks/squats/push-ups/pull-ups, but I was quite happy to discover a few new pairs of muscles which seem to be forgotten in my wider training.
To be honest I don't think yoga will make me climb 8a suddenly, but I quite enjoyed the stuff and it seems to be good for me, so I'll try to continue.
