i don't exactly do it but i go to the Y and know people who do. it involves doing cardio like running, biking, Zumba,etc with core exercises like pilatte's, weights and other strength exercises. personally, i do Zumba(a fast latin dance program like jazzercise) Tai Chi, brisk walking and some weight training. I tried pilatte's which sounds kind of wimpy, but it and yoga are really good for core body work. my shoulders are all screwed up from 35 years of being thrown thousands of times in Judo, but i can still do some weights. i'm 70 and weigh what i weighed in high school when i did 1000 sit ups in one sitting. my BP is 115/65
