As a result, these exercises were popularized as the best way to work your abs. But the reality is that your abs have a more critical function than flexing your spine: Their main job is to stabilize it. In fact, your midsection muscles are the reason your torso stays upright instead of falling forward due to gravity. So your abs and lower back actually prevent your spine from flexing. The upshot is that if you want better results from your core workout, you need to train your abs for stability. The future of abdominal training is a focus on dynamic stabilization – not movement. Our new DVD – Ultimate Core Training – 21st Century Torso Training is now available. This DVD contains a multitude of exercises and progressions and non-traditional core training.
