A virus that can mutate a human body into having insane strength and dexterity

Im writing a story about a boy in the year 2033 that is immune to a zombie like virus (world war z like zombies) and when he is bitten instead of turning into a brain dead zombie/infected his body is able to co-exist with the virus without killing him. He ends up gaining super strength and speed. This virus quickly mutates the body for different tasks (ex. an infected with a bullet proof head, one that spits stomach acid or keratin like armor ) is their a way to implement increased strength without changing muscle size like cartilage reinforcing muscle tissue or bones being unbreakable? He also has an ability which lets him use a certain mutation from an infected hes eaten is this probable? he also ends up developing heightened vision and hearing.

i know the formatting is weird and hard to understand but im sleep deprived and running solely on coffee so give me a break if you have any questions feel free to ask and ill answer em'
