I don't like the look of it; it just seems a bit mad to me. I don't necessarily think overtraining is a worry, but I would be concerned about injury to your joints with all that squatting and deadlifting. Remember that your joints take longer to recover than your muscles and you are doing a TON of low back intensive stuff. Nothing like a back injury to make you put the brakes on your training, trust me.
And you said that you recently hit a good goal, that's good, so if you're training well just now and hitting PRs, why change anything?
Truth is 8 reps burn me out after 2 weeks . I admit that an 8 rep workout is possibly the most intense scheme with best results for me but the fatigue it causes me is ridiculous after doing it for 2 weeks. For example , I don't think I could've hit 305 for 8 today so I did 315 for 5 instead and a couple sets of 5 as well with other numbers..
315 for 5 is not that different to 305 for 8, and I doubt it stays under some magical overtraining line. I think all this talk of burning out is in your head - you expect it to happen so it does. There's guys out there doing more than you and they don't overtrain or burn out or whatever because it just doesn't occur to them it could happen.
if you feel fatigued, take a day off. Don't overcomplicate it. Still don't feel recovered? Take another day off and eat a bit more.
I mean you're talking about burning out or whatever, then you post a routine that has you squatting or deadlifting every single day!
I would just keep doing what you're doing, eat a bit more and rest a bit more than you are currently and chill out man, you're doing fine.
