i am currently on the bill starr routine and my 4rm for squats has been stuck at 275 for the last two weeks (couldn't get all 5). my workouts have been shitty since then so I figured it was time to start deloading.. was gonna do 3x3 last friday for squats and had the hardest time just doing 245x3 for my second set. well, i just got done working out today and i couldn't even get 225x3. what's the deal? this has been happening to all of my lifts. they peaked about two weeks ago and have slowly declined since then. i changed up my routine to try and accommodate this (AKA deload), but I can't even get through deloading. maybe I'm doing it incorrectly? my diet has been the same. sleep's been the same. should i just take the week off or what? SIDE NOTE: my left knee has been bothering me for the last month and a half or so..... any tips on getting them healthier?
