So when I do concentrated curls according to this http://www.ironmagazineforums.com/showthread.php?t=35431 I flex my muscle 1-2 seconds when its at the full point like curled high.
Also do I do with when I use ez-curl bar?
And does this help gain strength to?
-How long should I work my biceps doing this for how many excercises and how many sets.
