I just realized I have been doing pushups wrong my entire life

I was going for a run with one of my friend. It was cold outside so I decided to do some pushups first.

He watched me do 2/3 then he laughed and called me an r-slur because of my form.

Now I do 25 strict military pushups, first 20 in a row, then downward dog pose to let a breathe in (without breaking touch with the ground) and then 5 more quickly before I'm out of breath.

My friend was in the military (chair force but still) and he told me that's not the correct form.

Apparently you don't have to go chest to the floor every time, there can be enough space between your chest and the floor (3-5 inches).

I tried that and immediately I could do 25 in a row without even pausing for a breath.

I'm not that weak. Just my form is shit
