Double Stimulation Training.
I'd much prefer to call it stimulate then deliver. That is, stimulate the muscle on day one, then deliver it some much needed nutrients rich blood on day two via an ultra high rep set with negligible resistance.
To double stimulate (a muscle) is to actually get smaller and not bigger! Once stimulated via the catalyst that is resistance training, further stimulation (or an attempt to do so) would only serve to degrade it / destruct it further rather than construct it. There's a time to destruct and a time to construct. Bringing much needed blood into the muscle fibres would serve to facilitate the healing process, from which we're then able to build upon what we already have built.
And since we grow by mere millimetres instead of centimetres or inches, it goes without saying that every little bit you can do to facilitate muscle fibre recovery, would in turn help you achieve your goal that much quicker. Furthermore, performing an ultra high rep with low weight resistance (at the most appropriate time of all), would act like anabolic steroids (without resorting to such drugs). This can be achieved due to the fact that through the high rep set (and the blood that is delivered by it), the refilling of your muscle glycogen is optimised, promoting muscle growth as well as strength. We've all heard how training affects muscle protein synthesis, well, here we're talking of the facilitation of muscle glycogen resynthesis / supercompensation, and its effect on muscle performance and growth.
Who here doesn't know the feeling of flat muscles?
Who here doesn't know the feeling of fully loaded and tight muscles?
If you prefer the latter, then you belong to the stimulate then deliver camp, period!
