Question

Feeling pain while lifting is a signal from your body that you are building muscle.

Answer 1

That is false because you cannot just cannot gain muscles starting off on the bat you have to do more then just lift weight.

Answer 2

It depends. Any uncomfortable pain is not good for you!! So if it hurts your probably not building anything!!! Usually if you are building muscle you wont feel anything...your muscles will just feel tired. You will usually feel the pain after your workout and thats when you should roll out your muscles to break up the amino acids!! Hope I helped!!
