In reply to McHeath:
All the time not laterally but just the ability to bend back. For example if I press my palm flat on a 90 degree wall fingers pointing upwards I can just about get my arm to 90 degree to the wall but there is a fair bit of resistance in the forearm. If I were to try and do the same movement with no force on it I might get to45 degrees before my fingers start to curl.
I had a look into the carpal tunnel mentioned above but I can’t say I get any tingling in thumb or fingers. I just notice after a climbing session I need a good 3 clear days for the right forearm to recover to go at the same level whereas I have mates who can do two days on the trot no issue.
I generally stretch my fingers/wrists whilst I’m climbing but warm up on very easy stuff as opposed to having a separate specific warm up stretching routine which sounds like I need to do
