We are achievement-driven and overly active in the wrong ways. As a result, we become impatient, frustrated and bad-tempered. We expend far too much energy and take too little time out. Yin is much stronger, so you need less to create balance. Half an hour in a day of rushing round is sufficient.
People go to an aerobics class to relax.
But they arrive with low energy levels and deplete them even further. The body is under attack. By the time they are 35, they are searching out the yoga class. My aim was balance - between strength and flexibility, body and mind, yin and yang. I worked on Chi Ball for three and a half years and discarded as many ideas as I included.
