Yoga is movement and balance at it’s core. I do not teach yoga, but I do teach foundation movements along with progressions to include balance and multiplanar movements that are very yoga-like. Why couldn’t you teach yoga without the full on mindfulness? For many I think the mindful side of yoga is presented in too steep a learning curve anyway. Just like learning any form exercise, each piece should be introduced and progressed in a manner that the client is comfortable in doing. And a fitness professional should follow their instincts on when not to include some aspects of a program. I discuss these types of things with clients to make sure that I am not misreading them.
