Cat-Cow is a yoga pose used to improve overall back mobility, posture, and balance, especially for those with troublesome back pain. As with most yoga routines, synchronizing this movement with your breathing may lead to better coordination, intentional focus, and invigorated prana (the life force of the body.)
The simple flexion and extension of the spine can relieve tension all over the back and neck, and may help with toning the gastrointestinal tract and female reproductive system, and may include a number of spiritual benefits as well. It’s accessible across all levels of fitness, and very simple. But there is a beauty in simplicity.
