Take it from a guy that has a lot of big pieces done...
Let the ink heal out before you go back to rolling. For many reasons but the main ones being:
-infection: your new tattoo is like an open wound, and you do not want to be rubbing all over the dirty mats (regardless of how much they get cleaned) and risk getting some crazy ass infection
-screwing up your ink: if you do not let the ink heal correctly, and you go and role, and you pull off a bunch of scabs/healing ink...you may rip the ink out (for lack of a better term), meaning you need that area inked again, or worse you will get a nasty bit of scar tissue that will destroy any fine lines laid down...
So either finished your ink up before you go back to training
or
schedule enough time inbetween sessions so that you can go train for a while before you go back to your next session
hope that helps
