Of course, while this is not strictly about calisthenics, the way he explains shocking the muscles can definitely be used in calisthenics. What he describes is essentially "drop sets", where you perform an exercise that is difficult for you personally for reps then drop to a less difficult one for reps. You could drop multiple times as a method of muscle exhaustion. As some old timers would say, the first few reps are for strength and the last few for size.
My personal training business known as BodyRite Training is centered around two activities: eating and lifting. Results happen in body composition when we eat food that isn’t complicated and pick up stuff that is heavy. It may sound over simplified and silly but rest assured, I am dead serious. Clients that join up with BodyRite undergo a body composition evaluation on day one of training and then every four weeks.
When designing your training program, I suggest sitting back and analyzing WHY you are training? This is important as it should dictate HOW you train. The obvious example is for someone training for a marathon.
