My hands looks like bent after bicep curl. I have to force them to make them straight& pain while making them straight any remedies please?

Don't quite know wha. -t U R describing but if you do the curls holding the bar with Ur wrist hyper extended & hold the weight bar by Ur flexed fingers, U get the same result if U rest Ur head on hyper flexed wrists while reading or watching something. The sudden release of pressure causes pain, & it is hard 2 straighten them out. Grip the bar firmly wrists @ neutral & this should not be a problem. .
