What's the feeling about high rep (12-15) routines? I always notice a change when I switch up my workout routine and have been doing 10 rep since september. (june-august 5x5). About two years ago I was doing 15 reps and if i remember correctly, saw some results ... but there where a lot of other variables then too (diet, etc.). FYI, my workout is very similar from purevl's routine at 10x3. Is 15 reps too high?
