You reset your squats? Wtf. How many sessions did you try 290? You got 4 last time, right - you should just pretend you're not loco and put up 5 instead of going back to 265.
Fwiw after I do squats I sometimes try 225x?. I get like 5-8. Lol. Maybe I will just say it's b/c I'm so spent on my work sets.
Anyway, since I mentioned to my wife that I was desperately trying to stay ahead of you in squats she keeps asking me (every time she sees me on 2p2): "has Fake Busto passed you in squats yet?" Not "Still dominating that little tinyelf with the vests?"
