I've been training for 2 years now.. my overall strength and mass is increasing except for my biceps that are lacking. I dont understand because i train them like a b*tch and they wont gain any decent strength. I was told by someone that i curl too high.. could this be a serious issue? He mentioned about losing the tension during my curls. I don't know if that could be it. I do standing barbell curls, preacher curls, standing dumbbell curls and seated partial barbell curls.. all for 4 sets of around 6..8..8..10.. Please give me suggestions, it would be very well appreciated, thanks.
