Also: LOL @ asking these questions given your current regimen and totals.
a) have massive natural aptitude (It's possible. I progressed through the 'intermediate' sections quite quickly. I'm naturally heavily built with thick arms and shoulders, but I don't for one minute believe that the multiples you think are normal are commonplace in that timeframe)
b) Are lifting with horrible form/using screwy weights/somehow kidding yourself as to how strong you really are.
Most people in the gym never come close to being able to press their own bodyweight above their head whilst standing. Not even close.
I'm currently a solid 80lbs below my bodyweight for standing overhead press with free weights if I want to be safe and do clean reps. And it's a damn slow crawl to improve that lately. MMAMickey is right. If I could do my weight, I'd be a beast. This is 3 years in from an admittedly somewhat weak-for-my-size start.
But multiples of body weight is a meaningless benchmark taken by itself. Smaller people will be able to do greater percentages, square-cube law and all. Look at it this way: the monsters that can bench around 800-900lbs? Strongest humans in the world? That's only around 2.25 to 3 times their body weight.
There are a few misconceptions on this thread. Firstly to the guy who has reached 80% of his weight goal, well done but getting the next 20% is damn hard. I am maybe 90-95% of my goals and fighting hard to get there but progress is a lot slower. Generally, the more advanced you are the harder it is to gain in general. Talk about the bodyweight equivalent standards posted as being easy once you have actually done them.
The assumption that bodyweight work does not carry over to weights is not true and have proved this on my self. Yes, endless pushups and pullups dont build max strength. As an example work up to a controlled full range handstand pushup (hands to shoulders) and see if you can overhead press your bodyweight equivalent. Provided you have worked the rest of your body, especially your core you probably will.
The fact that big guys find it hard to do things like pullups is a good reason to do them, don't you think. Also, "only 2.25 to 3 x bodyweight", LOL.
im pretty sure if you can press your own BW above your head after a year you dont need to worry about learning to fight
Most people who can do HSPUs have to cheat by using the wall. I can do them using the wall for 4-6 reps, it's really not that hard.
Edit: I went back and reread the post MMAMickey quoted. I think I get where MM was going with it. With the HSPU compared to press if you aren't lowering your head below your shoulders you aren't completely pressing your full weight. It would be like doing an overhead press without bringing the bar all the down to your chest with each rep.
It's similar to a smith machine in this respect. By not pushing perfectly vertically, you push the weight against the frame to lift it, instead of lifting the full weight yourself.
