Yeah so i read trough those articles and it seems like this guy has found the best exercises, but then i saw something weird, in the chest and triceps article he says that dumbbell press is better than traditional barbell bench press.
Well, i can do 75 Kg for 6 reps, but i can't do 37,5 kg for 6 reps which is half the weigh on each hand, that equates to me being able to move more weight when using barbell compared to using dumbbell, so how in the heck can dumbbell have more muscle activation?? you need to activate a certain number of muscle fibers to move a certain amount of weight, so you know, it makes no sense.
But say with the dumbbell row, i can use 36 kg for 8 reps each arm, but i can in no way lift 72 kg barbell row for 8 reps. even tough it's essentially the same movements.
So that led me to believe that it's more individual you know, we are built differently and respond differently to different exercises, rendering the article as more of a guideline not accurate fact.
