[DWIPump]

Sorry if I am posting in the wrong section but I am new at this. My ? is at what bodyfat% will I see more vascularity? Sorry if I misspelled anything, I spell like a 3rd grader!

The lesser the bodyfat coupled with working out, the more you should be able to see whats beneath, 5% 10% and 15% will all be different.
