A man should:
Weigh around 200lbs
Bench press 300lb
And press his girl over his head for multiple reps.
In the gym, that makes sense.
In real life, a man should:
* Weigh a healthy weight defined mostly by body type
* Be able to life one's own body with ease (all sorts of pushups, but also various weight lifts)
* Be able to touch all parts of one's body and have full range of movement in all joints
* Be able to do a full squat for reps on one leg...squatting with weight on shoulders is useless if one can't control their own body. Life isn't in a smith machine or evenly balanced.
While it is possible for a person to be able to do body weight lifts for reps and not be particularly strong, a person who cannot lift their own weight, yet can lift heavy iron is surely not strong.
