Hey guys,
So my trainer has taught me about pinning and receptors in muscles and why some are better then others to pin. He taught me a 3 finger trick to mark out my delts and usually works perfectly, but I still have to pin a couple times to get it right some pins. So my question is pinning tris really that big of a difference when it comes to receptors. I am pinning 300mg testE. The reason I ask is I don't have boulders for shoulders (working on it ) and I can pin my tris in the dark. I have pinned B12 for awhile and never have had an issue. Until I can get my delts down packed is it going to make a big difference hitting my tris?
Thanks
