[quote][b]Posted by:[/b] Pornstellar Ok I haz question! When ive done several sets of barbell curls (25 pounds, 12 reps) i ocassionaly feel an intense strain on the bottom of my forearm. It feels as if my veins might burst. It subsides immediately after I stop lifting though. [/quote] You should do compound excercise instead of things like curls (imo), it works out more muscles. And as for the strain, you should get that checked out, normally you should feel your muscles inflate a bit but you shouldn't be feeling a strain like that. Do you stretch beforehand?
