From the Chinese words for "Intentional Energy" and "Work," Qigong is a codified system of movements that aim to improve physical and mental health. In some ways Qigong is similar to practices like Yoga and TaiChiChuan; mindful, full-body movements are coordinated with deep abdominal breathing.
One of the beautiful things about Qigong is that it is instantly scalable; this means that exercises or forms can be easily adapted to anyone's current level of fitness. You can even practice while seated if you're not comfortable standing for periods of time. This means that people of all ages can practice together regardless of experience, which also makes it a beautiful way to connect with your wider community.
Qigong forms don't require any equipment; just comfortable clothing and only an arm-span of unobstructed space. These exercises can be used as a stand alone program for people who have been sedentary for a while, or as low impact "active recovery" for seasoned athletes. Qigong is also a great mental exercise for people who find meditation "too passive." It's gentle enough to repeat daily, but can have a profound impact on respiratory function, joint mobility, mental clarity, balance, energy levels; just to name a few.
