Have been taking a break from climbing for a few weeks because of a dodgy finger but was back at the gym last night and everything was awesome. On the walk home though I noticed my left arm was bit jelly like, kinda weak flexing my elbow. Felt normal when my arm was kinda straight but the more I closed it the 'weaker' it felt.
This morning it's pretty much the same, maybe a bit better. Actually doing stuff my arm doesn't seem any weaker, it just feels it. Normally I'd assume it was regular muscle fatigue but there's no soreness and I've never noticed it before...feel a bit of a twat asking, but is it anything to be concerned about?
Cheers!
