Need opinion,

in fact i love to do the bicep curl, but whenever i try to reach big pound, my left forearm alway hold me back, it's pain...

if i release the weight, pain will slowly fades..
i don't know either my bones, or tissue got problem..
any supplement to overcome this issue..

my right forearm doesn't have any problem..

So alpha, what did you do?
just hit big weight.. ignore about the pain?
