In my last blog on personal training I have attempted to show that exercise has and needs definition. Not all human movement is exercise. Most exercise pursuits today are recreation! I am sorry to be the one to tell you this but running or jogging or body pump etc. do not fit the definition of proper exercise. A true, well designed and safe program will, after each exercise session, stimulate the body to respond, at rest, with new lean muscle, stronger bones and an increased metabolic rate. Exactly how does running increase lean muscle or strengthen the bone structure?
