PREMIUM QUALITY AB MAT — Made from anti-microbial PVC leather and high
density foam, the Power Core ab exercise mat is both durable, comfortable, stays clean and provides the perfect amount of support for your
back and spine while challenging your core
muscles to the maximum.
1) While I added about equal quantities of fat and
muscle, ascetically I can not complain about the results 2) I adhered to the
density bulking protocol in
back loading which is the more aggressive regimen, had I stuck with Kiefer's other plan, I believe my fat increase wouldn't have been so great 3) Similar to my training during IF, I adhered to strength only workouts, i.e., I wasn't CrossFitting — coincidentally, this is also what Kiefer recommends in the book.
