How to engage your abs better in yoga (and real life too)
I realize that my last post how to improve any ab work for a tighter core is harder to apply to standing ab work, including any standing yoga pose, so this is a follow-up post to explain how to engage your uddiyana bandha, or abdominal lock while standing. Engaging the uddiyana bandha assists proper breathing during yoga, because keeping your core tight forces you to breathe fully into your ribs instead of your tummy.
The key is to understand to alignment of your pelvis. Come into a table top position. On an inhale, roll your pelvis out (like “sticking your butt in the air”) and shine your heart through your shoulders (“up dog” your chest). This is called cow pose, and demonstrates the “cow tilt” of the pelvis. Then, on your exhale, roll your pelvis under contract your abs up towards your spine. This is called cat pose, and demonstrates the “cat tilt” of the pelvis. You want to feel this “cat tilt” in the majority of standing poses in order to engage your uddiyana bandha.

Crescent lunge is a good pose to help one understand how to better engage the core in any pose. Think about rolling your pelvis under, tucking your tailbone forward (“cat tilt”), and straightening your spine upward. You should find that it is much easier to pull your belly button into your spine and pull your ribs together from this position. You will also feel a greater stretch in the psoas muscle of the back leg. Try to recreate this feeling in poses such as the warriors, camel, standing backbend, and all balancing poses.
PS: finding a slight “cat tilt” pelvis in your every day standing posture will help to create a flatter, tighter looking tummy!
