The Mainstream Still Doesn't Know Strength Training Beats Running. Why?
He is focusing on carb metabolism and other health-related issues. Those issues aside, I think general conditioning, or training as he terms it, calls for both strength and cardio-endurance efforts. Of course intensity is key, which is why walking has no fitness benefit for those under age 80. If he has arguments against burpees, heavy rope games, stepping routines, and jump rope, I'd listen to them because those calisthenics are strenuous, difficult, and basically unpleasant.
My simple theory is that if physical efforts are stressful and difficult to the point of pain and failure, they will make you better (as long as you are not truly injuring yourself). It has to be hard as heck.
