Sit-ups Are Stupid & Crunches Are Crap: How to Strengthen Your Core, Get Great Abs and Conquer Back Pain Without Doing a Single One! (English Edition)

It's time to change the way you think about, and exercise, your abs. Dr. Todd Sinett, a second-generation chiropractor and certified fitness trainer, explains why you should never do a sit-up or any version of a crunch ever again! Sinett's innovative new book—which includes a detailed exercise routine (illustrated with photos) and a meal guide—teaches healthier and smarter ways to get great abs without compromising your back and neck anymore. Sit-Ups Are Stupid and Crunches Are Crap, based on the science of flexion, addresses the key issue of core imbalance and the resulting (and totally unnecessary) pain. Dr. Sinett shows how achieving core balance will transform your flexibility, breathing, and digestion—and, yes, get you the abs you've always wanted. Great abs no longer have to equal great pain.
