I have increased my weights enough that I am now having a hard time holding onto the weight for all three sets. I bought some really stiff wrist straps but they only help so much. Are there better straps to use or some advice you guys could give me? I know it would be a no-brainer to say "add some grip strength exercises" but I figure I am taxing my grip strength as it is with every workout, so I don't see the point in working them even more.
