hey man i like curls too. how much do you deadlift?
I don't, never been to gym. I only use 2 dumb-bells, one of 2,5kg (for small warm up), and another one which can go from 5KG to 10KG, but I usually work out using the 5KG and rarely the 10KG.
I'm trying hard to gain back the weight I lost last year, but no success so far...
