I like the initiative and congrats on your first book....kind of got lost in the last couple lines of the rear cover.
1. Baby sitters and day laborers? I get it, immature/young and rough looking women, but it sounds like you're a pedophile and now questioning whether there should be 2 male symbols on the cover as traditionally, most babysitters are teenagers and most day laborers are men...just sayin.
2. The last part that says,"...they started a secret society of underground bodybuilders that culminated in an affair with a married billionaire"
a. Secret underground society of bodybuilder pick-up artists?This sounds like "The Game" theme only with pick-up artist substituted with body builder. Is that part really necessary? Your title is about working out, losing weight and not being single. (i.e. you're dating someone and in a relationship) I think the banging a married women part is getting away from your central message of creating a healthy lifestyle.
b. The subject in the last sentence kind of sounds like the society had an affair with this woman.
