thanks luqui and aczech. yup, aczech, love that 20 rep squat. it's a very personal challenge for me, though i wouldn't dare do deadlift 20 reps...that's just stupid for me. i finally nailed that freaking 166x20 after.....a month. first it was 14 rep then 15 rep then 17...and that was last lonth, which is last year, i loled. i would say 20 reppers helps my squats though I interchange 20 reppers with my actual worksets. so in a month, it's 20rep-workset-20rep-workset and that's per week..interchange. it's fun that way.for me to be not bored. now my goal is 177x20 then 188 then 200 and so on.
