what helped me develop better forearms is just carrying a sportbag in one of my hands (offcourse alternating between hands) instead of a regular backpack
otherwise both exercises are well, but the regular bicep curls work best for me, the ROM seems to be longer and I can really feel the squeeze at the end of every rep
"the squeeze" being a burning, allmost tearing sensation in the muscle through maximal contraction that gives me the nastiest pumps
it all starts with picking the right weight, that should be at atleast 80% of your 1RM according to the studies of Godfather Stoboy & Hettinger
if you can curl a weight for 12 reps it is too light for you, you should really struggle to get it up 7 times max
and when I talk about getting it up I am referring to the point where you think your arm might snap off and up to the point where the barbell allmost touches your shoulder. At that point when the muscle reaches allmost the top and you keep the tension steady you will feel the squeeze
>inb4 but all the tension in the muscle fades away if you go up too low or too high
I can only say try it
for me it certainly helped to shape my biceps and it is a concept I use for other musclegroups
also what I like to do when I feel that my muscle isn't getting warm and I can't up my weight yet is stopping the movement of a rep at the centerbase if it's strongest tension and starting the motion a new; that really tickles the fuck out of my muscles
