Push up tip #1: do more reps
That said, bodyweight training is a bit different, especially push ups. Once you can do 10-12 push ups, if you stay in this range going forward, you won't see results anytime soon, or ever. Doing 20-30 or even more reps per set is advised to increase resistance and stimulate the pecs more.
