I can't even do one push-up! How can I train my body to do push-ups?

Get in the up push-up position and hold it there for as long as you can. And don't whimp out, if you want results time yourself and stay for 3 minutes. Try it.

When I read the title I was going to answer seriously until I opened the question and read the first line. How are you supposed to actually play sports if you can't do a pushup?

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
