Question: is a six-pack of abs possible for me?

Six pack abs is a question of body-fat. You need 10% for them to be
visible.

I'm just starting week 4 of this:

I don't expect to get ripped because it requires a bodybuilder's diet,
which isn't worth it to me. But after only 3 weeks of the program, I
feel every muscle in my body tightening up, and that IS worth the
effort.
