If you've been performing ab crunches night and day without achieving the six-pack of your dreams, it's time to consider a different approach and a little bit of science when it comes to the most effective ab exercises. Cathe's approach is both scientific and simple. She attacks the entire core region with exercises that work all of the muscles in the core region, including the stabilizer muscles. She has learned through years of teaching group fitness classes at her gym in New Jersey which exercises are the most effective. She shares that knowledge on all of her ab and core workouts.
