you missed the point.
when the dow was 14k or whatever, wtf did people think was gunna happen, it was gunna keep going to 25k? of coarse not. lifting is the same way, its a cyclical process, ebb and flow, and if you want to increase your peak strength you specifically train for that, you will plateau eventually. thats all i meant. everything youve suggested is all great. but you cant call someone else’s routine shitty just because they plateau (although most of them are). their routine might have a completely different goal in mind, and the might expect a plateau. know what i mean?
youre absolutely right that a change in routine, and eating habits, and sleep cycle and etc can have an impact in strength, but i just dont want you to forget that the mechanical structure of your body has just as big of an impact in your strength as your lifestyle. for example, ill never be strong. i dont have the bone structure for benching 650lbs. im fuggin 5’9" on a good day and my wingspan is 6’2". my body is not built like every other real power lifter who has t-rex arms and are built like the kool-ade guy. my body has limited my strengths to lb/lb strength crap, not absolute strength.
on a sidenote, i deadlifted heavier today for the first time this season:
435x2, 455x2, 465x2.
im three weeks out of my low weight, high rep dumbbell routine, and one week into heavy lifting and my bench is almost as high as my previous peak. which is what i was targeting in the off season. im confident my squat and dl will catch up. shooting for 350 bench, 450 squat and 550 dl this season@<182lb, and im 167 now
