This thread has gotten me thinking about my own training, which is, I suppose, what all good threads should do.
So it's time to think things over. Everything I'm doing has evolved into low-rep. Time to juggle things around a bit.
Per your earlier thread, I find older lifters recover from higher intensity more than from overall volume training (meaning sets x reps x weight, not just sets x reps). I'm not sure why that is, although it's hardly universal - my ultra-marathon runner friend can handle volume in a day that would floor me if I did it in a week. But with my older clients, I worry more about having them do too much than having them go too hard - speaking in very general terms. If they do too much it's more likely to wear them down than having them go heavy for less reps - the total poundage with the heavier weights is less, and I think that matters.
So I'd recommend going higher reps with significantly lower weight - enough to matter for your reps but not so much total that it crushes you. You might want to look at something like EDT, or back off to a bodybuilding-type phase (3-5 sets of 10-20 reps of lots of smaller exercises) for a couple weeks, and then get back on the intensity horse. You can also try just taking a week or two for practice - pick a couple exercises you don't normally do (TGUs, Windmills, clean and press, farmer's walks), a weight you can handle pretty easily with them, and just practice for an hour or so. It'll end up being a fair amount of work done but nothing insane.
Personally, I kind of like EDT, done with technically simple exercises. It's really hard, but the weights are never so heavy that any given rep is hard. After a few weeks, it's nice to back off to heavier weights for fewer reps, no matter how much heavier that is.
