you amuse me whisper, chest presses activate more muscle fibres but not in the chest, if you're comparing which activated more chest muscle fibres the fly or cross over wins hands down, as for natural vs un natural you seem to be quite obsessed with limiting natural athletes lately, i can tell you now if people grew from doing 4 sets of dumbbell presses then everyone would be an adonis by now, but it doesnt work that way, you cant achieve your full growth potential through 4 sets, TUT range of motion, variety of exercise, angles at which the muscle have been hit, all comes into play, then you have to take into account the intensity the total time of the workout the oxygen levels in your blood stream the possability that your body could transport more nutrients to the muscles, you cant say natural lifters only need to do 4-5 sets for full activation -.-' the way workout routines are generall set it is to begin with a compound then the other movements are there to increase intensity, TUT and over all bloodflow to each individual head of that muscle, i.e with chest day, i start on flat bench, slowly work upto m 6 rep max, once i get to that i stroll off into doing some incline dumbell presses and incline flys, round 2 i do decline bench with standing cable crossover.... you going to call me un natural or am i just wasting my time doing all those movements for that well rounded chest ive worked so hard to achieve?
i can tell you something right now after 5 sets of HEAVY squats im just getting started on legs and so is everyone else, and as for the first set being 60% activation and not needing to carry on lifting aftr set 4... bollocks, you treat every set as if its the working set, you squeeze as if your gains depended upon it, even when benching the bar, i can pump up my chest pressing the bar, heck if i wanted to i can hold that bar not press it and still activate my chest to the point of no return, as for once you achieve 100% activation, thats when the workout begins, if you stop when you feel the best contraction of the workout then you're walking out after your warm up, hence why most guys wont grow, once you get that awesome contraction, we all know the one im talking about, THAT is the sign that we are starting to grow, you gain muscle through tricking your body into believing it is needed, YOU on the other hand seem to be telling your body not to worry it can pack on a pound or 2 every year you're happy with that, why are you gaining so little? oh yeah thats right because you walk out the gym as soon as youve warmed up and if you say you dont walk out after 5 sets then youre either un natural or wasting your time in the gym and if you say otherwise to that then you're wasting out time with such garbage information.
"you dont need to fully activate a muscle to get to grow optimally" okay then how do you get optimum growth of each muscle if you cannot fully activate such muscle? any lack of activation in the muscle puts more strain on the ligaments and tendons involved in the movements.
