I'm a fan of Dr. Yang for his Understand QiGong series and some of his books, but this DVD is probablymy favorite of all. I was looking for authentic Shaolin exercises, QiGongs and mind training, andI just so happened to see Kung Fu Body Conditioning. The warm ups are a great exercise for buildingup elasticity and fluid in the joints (harmonies), and the strength exercises are tremendous. No nonsense,delivered by students of Dr. Yang and the man himself. Demonstrations were perfect, no fluff. I can'tsay enough good about this one. If you want to train for Internal Arts or just to train, and you wanttime tested material, here it is.$37??? I've been charged $20 an hour to have someone tell me knuckle push ups and squats was Kung Fu conditioning.Just wonderful.
