I know they look easy, and men don't get on their knees for anyone(except a heart attack of course) right? So you will only lift 50% of your weight, but if you have a big upper body(or never touched a weight). 50% can start to look like a lot(50% of 400 is 200). Think about wrestling with Tony Soprano(don't think about it). When doing girl(means easy) push-ups your gonna need a pillow. The farther you spread your body out the harder it is(not sexual), kind of like an ab roller(not a sex move). The first picture shows the position for a regular push-up. The second is a variation for tricep(bigger than biceps) focus, because the elbows are close to the body. Once you master these you can move on to man or real push-ups(don't be sexist). From there you can move onto legs elevated push-ups(how I stay fit). If you want to go extreme then move onto the planks(david blaine push-ups or feet off the ground push-ups) and the handstand push-ups(someday).
