Any suggestions ofnachieving more definition on upper chest?  I am using the YouTube videos (Granny, etc.). and they are great.  Just wanting more definition. Does that require more weight of different exercise.  I am getting fine better results with just 4-6 pounds. Or more shoulders?  I am doing all of the videos on YouTube as well as ones in the total access.  Are you going to add those videos to this total access site and how do I access through my membership. I only use a Mac to view videos, not app on my phone.  Is that different?  Thanks for all that you do!
