Any bodyguard with that amount of muscle is pretty useless if SHTF
Actually, a bodyguard without some degree of size/mass/strength is a lesser bodyguard. This isn't cage-sport fighting, man.
The job description is to protect a person from physical harassment/attack. Having lots of surface area and bulk goes a long way to achieve this mandate.
No bodyguard will find himself standing several feet away from an opponent with some ref asking, "Are you ready?! Then let's fight!"
There will be no fancy-pants striking component and then an attempt to submit with largely street-useless holds, etc.
You're shielding an individual.
