In her latest book, Abs on the Ball, Colleen Craig reveals why the exercise ball is unmatched as a tool for building superb abdominal strength. Abs on the Ball uses a Pilates approach: a unique exercise method famous for building long, sculpted muscles and a strong back and abdominal core. In this groundbreaking book Craig shows how traditional sit-ups and "ab" machines actually limit the degree to which abdominal muscles can be trained and can even aggravate lower back pain and neck tension. In contrast, the very mobility of the exercise ball targets underutilized muscles, recruiting both deep and superficial abdominal muscle fibers to give rapid results.

Abs on the Ball presents a selection of over 100 innovative exercises adapted specifically to large (55 and 65 cm) and small (9inch) exercise balls. Step-by-step instructions are detailed in more than 250 photographs. The author also offers 15- and 30-minute workouts for all ability levels. These workouts not only build the abdominal core but also strengthen and train deep muscles in order to soothe low-back pain and increase overall body strength, balance, and coordination. 192 pages
