Qigong (Chi Kung)
is an umbrella term for various health and wellbeing enhancing techniques and practises, developed in China within the past 5000 years.
Qigong most likely has its roots in Daoist hermits observing nature, combined with various shamanistic practises, internal alchemy, and meditation techniques. The word "qigong" can be translated as "skill or ability to maintain life-energy". Qi or Chi refers to universal energy or life-force, Gong refers to work or skill.
Practising Qigong will make the Qi stronger; it will also help clear the meridian channels of blockages, resulting in better health.
Qigong requires a relatively small area to practise. The movements can be done standing, sitting or even lying down. Emphasis is on relaxation, and connecting breathing with the movements.
