you mean a full 6'
No way. Its more like 16-18'. From what I have read the reported way to aproxiatmate bicep size is 10' more than your wrist size. I measured my little brother arms the other day who is just a recreational lifter not even that serious into lifting heavy. He is 5 9' 190 and arms 17' cold.
I had 17' arms at 17 years old at a 5 8' at 160 my JR. in H.S. and I wouldn't consider myself a gentic elite. Chest was only about 44", but was at 5% BDF at the 160. Decent genectics, but not elite by any means. Most the kids on my H.S. Football/ Wrestling Team had 17-18' arms and we were all natural and the most of us weighed 160-200 with those measurements. During football season I was at 190 and Chest would jump up to 47" and BDF was between 8-9% MAX.
My buddy at work is a natural middle weight and he comes in at 170 sliced. Chest 46' arms 18' on stage.
Ok for all those picking the 260 plus are you taking into account the risk factors when choosing. I know a few bros on the board end up having liver issues and took a break and were on low dose HRT after that 200-weel. Don't know what they did after. What if you ended up getting hit with a risk factor.
