Strapping on a 60 pound weight vest almost akin to adding 60 pounds or pure iron/steel muscle to your body?

I think I’m 5 foot 11, around 160 pounds muscular and six pack— maybe 5% bodyfat? With my weight vest on, now I’m 220 pounds — pure muscle, still 5% bodyfat with a 6 pack? Nice.

Also with weight vest ,,,
