Hi JediDurron, Welcome to the forum.
Since I'm not from the US myself, I'm not going to recommend anything..
But as many others have pointed out here; if you are going to be good at push-ups, sit-ups and pull-ups, it's best to do just that, and don't waste too much time on weight training.
One other tip is to also train your back.
Without a strong back, these exercises will be much harder, and you can actually injure it too.
This is a mistake that many do.
Good luck with your training.
