Ok so i started working out tuesday (cardio when i wake everyday except weekends, lifting every other day after cardio and work except weekends). Today was my 1st day doing bi's, i was disgused and confused. I did dumbell curls (one arm at a time) and when i took my left arm to failure on my last set the right arm was still EASY to curl. I might have to use 15lb difference in my arms to fail at the same time. I don't want to do that obviously i want to get them both equal. Whats the best way to get them equal?
