How to Tan to Highlight Pecs?

I am trying to figure out the best way to accentuate pecs with tanning. When tanning, should I:
1)let the skin covering the muscle bellies get darker by applying a thin line of low SPF (4)block as an outline to each muscle

or

  1. Do the inverse and have the skin in between muscles be darker than the skin covering the muscle bellies.

Essentially is it better to have dark or light outlines to muscles on a white guy.

Btw, I am only talking about subtle differences in shading nothing too dramatic.

This is silly.

This better be a female posting, or a joke. If not, check to see if you still have testicles.

Dude, not that I’ve caught my breath from laughing, let me say that you have entirely TOOOOO much time on your hands. baaaahaaaahaaa
