when i did pumping, my shoulder hurts, not sure if it's the joints or muscle, but it feels more like the joints, what is the implication of this?
should i continue doing pumps or should i stop?
If your shoulders are hurting then I have to say that your form is wrong.
There are many problems with shoulders when your form isn't right.
What I suggest is look up the proper form and try it with less weight the next time you lift.
It is really important to have proper form, it helps the muscles grow in proportion and reduces the risk of injury.
For example not flailing out your elbows when benching or have them at a 90 degree angle from your body but instead have them below your shoulders to reduce the stress on your shoulders and also get a better pump on your chests.
All these things you can find easily on the internet just search for proper form for whatever exercises your doing!!
It is very important
