“There isn’t a single crunch or sit-up in The New Rules of Lifting for Abs. Instead, Schuler and Alwyn Cosgrove base their workout around planks and side planks…This isn’t a revolutionary concept among fitness professionals. But you’d never know it by watching what people in health clubs do.” —Yahoo Sports
“All the crunches in the world won’t give you the six-pack you want. These exercises will.” —Men's Health
“Cosgrove and Schuler’s groundbreaking program is based on the concept that a healthy, sculpted body is the result of your muscles working the way they were intended.” —Women's Health
