91 Day Wonder Abs (e-book)

A day by day ab program that runs for ninety one days, not a set of exercises to fit in where you can. It opens with the diet side, because Frank is blunt that a small muscular waistline comes from cutting the quantity of food, and he lays out exactly what he eats and how he handles hunger when it comes in waves.

From there it covers stomach vacuums, tensing the abs with breath control, and getting waisted, then moves into the programme itself. Day 1 through Day 31 of ab workouts with diet instruction built in, then beyond the 31 day programme, Day 32 through Day 91, and finally what to do from Day 91 onward to maintain it.

This is the programme Marty Ogilvie credits on the home page.
