exactly, however natural genetic potential varies from person to person. one guy may reach 250lbs at 5'10" and 12%bf naturally, while another guy may max at 190lbs at same height and bf. genetics vary greatly and can be cruel or kind, it's hard to say. my best friend is around 5'9" and about 230 and maybe 17%bf, natural, doesn't diet well at all and training is between average and poor. his dad is 5'6" and maybe 160lbs soaking wet. I see a lot of guys say "well my dad is...so..." and that may not mean as much as some would think.
