If Jay's physique was naturally attainable for you (obviously it's not close to natural in the real world).
Their waists are about the same size too
Fu*k no. See them side by side in person and let them let their belly's hang. Jay even on stage I believe has a 35-38" waist. Its not his fault but you can't be 5'7"-8" weighing 260 with a 30" waist.
One is 3 times Mr. Olympia the other is a liar who claims to be natural....
