So we know that working the body with slow reps but high intensity creates long and lean muscle.  Such as doing your push-ups to the count of ten going down and the same coming back up, we can do fewer but the intensity is high if we go to exhaustion. The same principle can be applied to any exercise,….squats, dips, lat pull downs, hill training or sprinting (bike, run, paddle etc).  It seems there are more benefits to this training and possibly even more valuable.  The article by Dr. Mercola is a bit lengthy but the interview is worth watching as it suggests this type of exercise may also be disease preventing.  I’m all over smarter workouts with possibly huge benefits!
