So tonight my crazy workout finally caught up with me. I had no energy and no drive, it wasn't very pleasant so I did my squats and a few other lifts then called it a day. Tomorrow is rest day which I think I really need. I'm now planning to switch back to doing the 4 main lifts once a week, twice a week isn't giving me enough rest time especially as I'm lifting a fair bit.
I'm contemplating starting up 531 on Monday, but I'm in two minds. The reason I stopped 531 before was high rep deadlifts were weird and I wanted to try some stuff out with bench. However my lifts were really good and I made some great progress on 531.
So with that in mind I may test my bench press max this week (doubt it will be more than 155, but I'll try for 160). I'm not sure about doing a squat max in my non-fresh state, so I may go with 190 for 531.
