Why when i am doing push ups with my?

Question

why does my lower back really get a burning ache when i am doing push ups with my feet on the couch and my fists clench on the floor is this normal or should i see a doctor or what some advice :)

Answer 1

its just the muscles and joint working hard. Its the same thing you get when you stand up with your head looking down for a long time, i get it when im doing my GCSE artwork at school. Also, i will arn you that although its good you dont wanna hurt your wrists but also resting on your knuckles puts alot of pressure on them and you can get arthritis later in life. I learnt to do them with the palms of my hands and everyone else does so i dont suppose its too bad.

Answer 2

You should only move your arms and do them slow and steady. Why on your knuckles???

Answer 3

Go see a doctor.
