I swear somebody could step on my back and my elbows still won't bend if my arms are close to my body. I can only do pushups with my arms fairly wide. I'm really close to being able to do one with wide arms. I practice on my chair every day and there's a playground nearby with a low step that I practice on, too. I'm using that playground to do negative pullups, too. I will get there. I'll be able to do both pullups and pushups someday, just not narrow arms on the pushups.
