unlikely that you will get biceps pain from climbing, except from underclings.
with your hand facing the rock, you will be using your brachioradialis*.
try holding the wrist of the effected arm with your other hand.
turn the hand on your bad arm to face you (supination) and bend and straighten the bad arm against the resistance of your good arm.
now turn the hand of your bad arm so you are looking at the back of it (pronation).
do the same as before.
which one hurts more?
whichever one that is
repeat this slowly, maybe ten times, morning and evening or whenever you think of it.
if pain persists, see an osteopath.
(if you do chinups do them do them with your hands both 'forwards' and 'backwards'
if you encounter pain either way, use a chair and support enough of your weight to avoid pain. make sure that you work equally extending as flexing.
in fact, on the painful hand orientation, don't bother pulling up (stand up on the chair) but work the lowering down almost to the point of pain.)
* an attempt at credibility, the BR is under the biceps, so feels similar. |
