My quads were a little sore from strongman training, regardless my form usually looks like that at heavier weight anyways. I might have been able to do 365x5 if I was fully recovered, i think. Yes, I've tried olympic shoes and I feel way weaker in them and GM the weights a lot more.
I started 5/3/1 for squats, hoping to add some mass. I've never trained more than 5 reps, so hopefully change is good in the long-run. I will be doing it for 3 weeks only and then switching to a strength phase.
