Tai Chi, Yoga, and Qi Gong

Tai Chi, Yoga, and Qi Gong—they’re not like other workouts. While a long swim or jog might leave us
drained, ancient mind-body practices such as yoga and Tai Chi have the power to do just the opposite: They produce more energy than they consume. When we practice yoga, Tai Chi or Qi Gong, we feel calm, invigorated, clear-headed. We experience a sense of renewal on all levels.
