Welcome. Pretty good numbers for a 60 yr old dude.
Can you do, as you wonder about, the four-day split of two on, one off, two on, then two off; repeat (Fr ON, Sat. ON, Sun OFF, M ON, Tue ON, W and Th OFF)? The extra recovery really helps, and works well with 5/3/1.
If you visit my log, you'll see what I do. But basically, its this:
Monday: Bench/Press (Heavy BP, light press), chins or other accessory work
Tuesday: Squat, sled drags. Or rows or something if weather is too bad for the sled
Wed: off
Thursday: Press (Heavy), Light bench, or dips, or dumbbell bench; chins
Friday: DL, sled drags. Or chins if I didn't do them the day before.
Weekend: off
Super good schedule with lots of recovery built in; lends itself to 5/3/1, or Texas Method, or each lift once per week... you get the idea.
Good luck! I'll be watching.
Tom
