I've been wanting a tattoo of a crown of thorns I've had picked out for a few years now and i'm thinking of getting it this weekend. Problem is i want it on my upper center back right where the bar rests during squats. I don't have any now but in the past in workouts that were primarily all squatting I've got a small callus there. Does anyone else have a tattoo there and ever had a problem with it? I don't like using a pad because it sets the bar farther back than i like it...
