The Legendarium isn't a comic book.  The Legendarium is epic poetry.  If you go into it looking for hard numbers to attribute to feats you are going to be disappointed.  They simply don't exist.  We, as fans and readers, don't know.  

We know that Númenoreans are taller, stronger, faster, tougher, smarter, and more long-lived than normal humans.  We know that their full might and splendor completely outclassed the forces of Sauron (with the Ring) such that Sauron didn't even bother fighting them because he knew his armies would get absolutely slaughtered.  

Our best hard feats for what a Númenorean is capable of is from Aragorn.  The long chase of the Uruk-hai is a good measure of his stamina and toughness.  You could probably get an okay measure of his speed from that chase as well.  It won't tell you how fast he can sprint, but more how fast he is cross country.  His ability to fully use a Palantir and directly defy the will of Sauron is a good measure of his willpower.  Him cleaving a steel helm in twane is a good measure of his strength, though part of that may be from his magic sword.  

I honestly couldn't tell you how many pushups he could do.  No one has that information.  Probably more than any real life human has ever done at one time.  He probably isn't as fast as the fastest human runners ever, but he has the potential to be just as fast or faster if he had modern techniques, training, and equipment.
