. Good news. No longer getting much muscle pain after sessions. Bad news. Really bad pain inside of left knee. Felt it twinge whilst doing squats on Wednesday. Feels very much like I shouldn't push my luck and give it a week or two to settle down. So, what do I do? Skipping the squats and deads means there's no real point doing any more of the SL5x5 routine. I was thinking of doing various other upper body stuff, in the 5x5 pattern, until I can squat again Oh, I had some advice (which I missed earlier, damn) about pushing my knees out when squatting. Hopefully that's the solution to my issue, rather than me just having bad knees in general - which I already knew about.
