Hojlund is already physically developed though. I wouldn't want him getting any bigger at all otherwise he becomes Lukaku.The rings dudes, yes.
Hoylund doesn‘t need shoulders and arms like that, unless he‘s planning to do a goal celebration routine spinning off the top bar of the goal.
A lot of gymnasts look trimmed off, not bulky at all. Kinda like what a perfect athletic body could look like cause it is in shape all over.
