@ilovejesuschristourlord Okay, first of all let's stop calling them 'girl push ups' - so many women can do a full push up from their toes despite it being anatomically more difficult for women to build arm strength than men. They're modified or assisted push ups.
Now that I've got that out of the way, as I mentioned, it is more difficult to do a push up if you're a woman so don't feel bad for not being able to do them yet! It's also a full body move - it involves your shoulders, arms, core, legs,
everything so it's not a beginner move by any means. Also lots of men do push ups, but their form is all over the place so that doesn't really count IMO.
I'm building up to push ups too and a huge revelation for me was that knee push ups don't work all of the same muscles as a full push up. So while a modified push up is fine, to really build up you have to do push ups at an incline. Start from pushing up from the wall, keep doing this until it's easy to do for 10 reps. Then stand on your toes and do a wall push up. If that becomes doable for 10 reps, try the kitchen counter, a desk. Then repeat for different angles until you think you can do them from the floor.
As others have mentioned, planks will help you build your strength (a push up is a moving plank after all). Negatives should help too. Also, I'd recommend doing wrist strengthening exercises and warm up the wrists if your wrists give out before other parts of the body.
Finally, I couldn't even do modified push ups for ages and that was linked to generally having skinny arms and not being able to build any muscle. Something that didn't click for me until last summer was nutrition. I didn't get enough protein so I wasn't building any muscle. I finally have a little bit of strength after changing my diet to incorporate more protein on a regular basis and it has changed the game.
Good luck!
