Even though yoga was "invented" and practiced by men for 1000's of years nowadays it has a huge female following. There is really no mystery why- women need the benefits that yoga can bring.
If you have taken or seen a Yoga class you may have heard "Lead with your Heart Center" (or something else similar). The Heart Center in Yoga refers to the Heart Chakra. The Heart Chakra is the 4th of 7 Chakras (or Energy Centers in the body). These centers are often used as reference points in Yoga, Chinese Medicine, Thai Massage or other traditional healing methods.
