This 60-minute lesson continues the practice of flow, adding in the element of strength building. With three, 5-minute segments that include the use of weighted tai chi balls, you will feel the muscular benefit as you continue to follow your instructor and the other students. If you don't have weighted tai chi balls, you can use 2-pound dumbbells, soup cans, or water bottles. And as Mr. Ross explains, you should feel free to put the weights down at any time or not use them at all, because there's no rush and no place to go. You'll begin this lesson by opening your heart, and opening and emptying your mind. Just follow along and keep breathing. In this practice, you will see Wagging the Tail, Snake Creeps through the Grass, and Swimming Dragon, among other tai chi movements.
