Concentration Curls vs Standing Curls?

Question

When i first started working on arms i did lots of chin ups, then i hit 20+ and went to Concentration curls and ez bar(80), i was able to max curl 62.5lbs(one 2.5 weight added only to one side :/).

Now i've restarted (after a pulled tricep right arm 5 months passed)and was just curling 45s standing, and doing some ez curl bars, and i noticed that my concentration curls were quite low. When i focus mostly on Concentration curls though, i cant do too many standing curls. I think that concentration curls make me able to lift higher weight(55lbs full range, 60lbs 60% range) but i feel like standing curls make my biceps burn more even though im doing 4 sets of 8 reps. Am i doing my seated curls wrong, or is it just power vs endurance(standing) im really at a loss. Sorry for explaining this so poorly, heh. I want to gain power and keep some endurance in my biceps. Thanks.

Answer 1

with isolation exercises there is always a point where you can not progress any further. the muscles of the shoulder girdle and forearm are possibly probably holding you back. not quite sure what the focus is on curling so much, the bicep is a relatively useless muscle in terms of power and functional strength. I also don't know or train many pro bodybuilders that use 55-60 lb dumbbells using a full ROM. personally my arms are 20" cold and I've never curled more than 55 lbs, but I really don't train my biceps directly much either. I let my heavy back training take care of them.

I agree, spending that much time on the biceps isn't really necessary. Spend more time on the larger muscle groups and doing compound lifts rather than isolation lifts. Thats how your going to develop power.
