Here is an example:

Tanks a nuke. Lets an amped meta-villain beat on him until he exhausts himself and fatigues. Snaps his neck. 🙂

If Brit from Image comics is an acceptable answer, then the answer is not Brit at all but Butterball, from Marvel Comics.

He has essentially the same specs but with even less physical strength than Brit.
(Actually, if Brit is "peak human" he's not all that weak by human standards at all and a LOT stronger than Butterball.)
