Dam bro.I am 215 and 10% BF. Takes a lot of work doesn't it? No one in my family has ever been in shows. Dad used to go watch arnold when he first came to the states, and I went to a MrO one time with dad and saw a guy win that had one leg totally undeveloped. It was early 70's and a guy named Franco won. Never got interested in that scene, and never read the mags much. I guess because I always heard dad say they were all full of shit...in denial of juicing and saying supps did it for them.
I also have no idea how to pose...except for wifey of course....lol. But I do admire their discipline. I have had buds in shows who come back saying I would have won it, but it just ain't my thing . Also I see these guys not workout as hard as I do but use a lot more juice and they all use insulin which isn't in my book. For insulin I just say no!!
Not trying to discourage you in any way.I am impressed. Try to hold on to that weight and BF and then next go around you can reach your goal.You are my age too...so get to it while the sun shines.
