I am a 15 year old boy.
Height: 5 feet 6 inches.
Weight: 61kg.
I am unable to do push-ups properly. I can do up to 8 knee push-ups. However after that I can't keep my shoulders in their place and they come up.
I can't do even one complete push-up.
What can I do to do complete pushups? Please suggest some progressions. I have been doing knee push-ups for about 2 months now. Any help appreciated.
