How to put on some Popeye arms...
(No native English speaker, so my apologies if this question is not precise enough.)
I've been training hard lately, fighting and weight-lifting,
and my hands and my wrists hurt more than usual these days.
When I complained about it to a friend who is a free-climber, he recommended me to
take some time to train the muscles in my forearms and my hands that are used to stretch the hands. (As opposed to the muscles that are used to close the hands when gripping, which are usually training with all arm exercises.)
So, my question is, how can I do that best?
My buddies have since recommended me to try some spinach,
but somehow I think I know that won't get me that far...
Thank you in advance,
