Iv been doin the 3/3/3 system
I done several different ways over the years and most of them seem to work, including the 5/3/1. It seems like a good idea to change your routine up if you feel like your hitting a plateau.
the 3/3/3 is very weird because you fell like you can actually do more, especially on the first 2 sets... but you have to stick to it and only do 3 sets...
Numbers keep going up so ill stick to it.
