anyone had experience of the Pace exercise program?
Dr Al Sears contends that long duration regular cardiovascular/pulmonary excercise just DOWNSIZES the heart.
Do you think you need long punishing workouts to improve your fitness? Think again. Dr. Sears has developed a PACE workout program that allows you to, literally, pace yourself and prevent or reverse heart disease in the process.

Unlike conventional interval training regimes, the PACE program focuses on the rest periods between the intense intervals. After you exert for several seconds or a minute you have a recovery period of 1-2 minutes or more in which you focus on getting your heart rate to within 20 beats of its resting rate. In this way you increase your lung capacity (and your longevity) and strengthen your heart.

Dr. Sears provides many different examples of PACE workouts, none of them lasting longer than 15-20 minutes, using the outdoors, pool and many different types of equipment. There's enough variety to appeal to anyone. You can use any style of exercise you want as long as you progressively increase the intensity and focus on lowering your heart rate during the recovery periods. You have the freedom to adapt the program to your own preferences and fitness level
