Sully needs to lose some abdominal fat and strengthen up his core. He's transitioning from fat kid to pro athlete.
Sully is listed at 280 pounds. I don't believe he's at 10% body fat. I'm guessing he's at around 13%. That would give him around 37 pounds of fat on his body and 243 pounds of lean mass.
If he can get to 6%, that would be a weight of around 260 pounds, with 15 pounds of fat and 245 of lean mass. I'd rather have him at 270 with 255 of lean mass and 15 pounds of fat, something he should be able to do in a year, with the right diet and exercise (assuming he can exercise within a couple of months after the surgery).
