Undercling strength

[Erich]

Hi-

I am preparing for a route with a really hard undercling move.  It is a lift-the-car-off-the-baby type thing.  I suck on underclings, partially due to an injury to my right wrist a few years ago.  

What can I do to improve this area in my climbing?  One question I have is, would bicep curls and/or pull ups (palms facing in) be effective?  If so, which would be better?

I think from an isolation perspective biceps curls are your best bet. I would also do some one arm pull-ups (take weight off if you need to, or do offset pull-ups). Core strength can also be a factor in hard undercling moves, so consider doing some core work too (see next week's blog post on RCTM.com).

Once you're in your power phase, build some boulder problems with hard undercling moves. Half the battle is learning to dyno from an undercling, which is a sensation we seem to want to resist for some reason.
