A prime Cedric McMillan... A prime Gunter Schlerkamp... A prime Victor Martinez (plus a couple inches of height)..
Guys like Flex Wheeler represent aesthetics, but his actual skeletal frame is smaller than you'd like, such that while he is insanely muscular, he isn't really a big guy, the kind that intimidates, makes women feel a certain kind of way lol..
Guys like Ronnie have that insane size, but they lack the kind of "sexy" to their physique that you'd want for walking around everyday...
What are some factors... ?
(1) number one factor is your overall frame.. height, clavicle width, etc... Gotta be a big dude..
(2) factor number 2 is aesthetics.. you want the flow and structure and conditioning and shape to look good, sexy, strong, statuesque
(3) factor number 3, enough mass in the right places to be at least somewhat freaky... Big chest, shoulders, arms, upper back, traps, and at least calves... If you can get away with any muscles not being developed.. if you can get away with weak points... It's lower back and thighs... Just make sure you are lean
