Lol....if you think those NFL guys are not on gear because they look softer. It's dumb to compare them to bodybuilder who are using 3x more drugs
Example
Nfl player may use just 300 mgs of test, some gh, and may be some tren.
A pro bodybuilder will use 1000mg test, 500 mg tren, and in some winni, some anavar with with 20 iu' s of gh per day so yes, bodybuilder will look extreme compared to NFL player, doesn't mean there not on gear
You have no idea what your talking about
Op....to answer your question, it depends on his genetics, some guys are naturally super shredded.
My cousin is 38 has always had abs like those in the pics, rarely ever trains, and when he does he gains easily but due to his super fast metabolism he loses it just as fast
There called ectomorphs.......
If your meso or mesomorph you going to have to take some gear to get that 5-7% body fat look you see in pics.
Mesomorph can sustain there muscle and gain it fairly easy but have to do cardio and diet.
Endomorph have the hardest time dieting down to low % to see and.
So it depends on your genetics
And most of those guys are on gear.
