the only thing i do is i lift, 3 times a week. i tough the problem was that my forearm was weak so i started doing wrist curls last week, other than that i have always done dumbbell curls because barbell curls has hurt my forearm since summer.
i did work at an electronic and home appliance store for on week as a school project. basically what i did was that i and this employee delivered stuff like washing machine, refrigerator. some of the washing machines was ridiculously heavy at 100 kg but i doubt thats what did it. i mean i have been doing deadlift for over a year now and that has never hurt my forearm
as i said it hurts when i curl with a barbell, throw stuff, help someones barbell off the rack when spotting bench press. i naturally tough that weak wrist extensor was the problem but i am not sure.
anyways to help you understand where, when curling the barbell with the palms under the bar it hurts on the
