OK, I tried this yesterday... it was chest day and the every other one where I do flat bench, so I started with that...
I did two warm up sets of 12 at 135 and one set of 4 at 225 just so I wouldn't just jump onto heavy... I rested for like 4 minutes and jumped on 275. My shoulders did not like it. I did it anyway, and went down from there... did some dips, some decline presses and some incline dumbbells, all heavy, and I'm sore as a mofo today. So idk if it was those reverse pyramids or just the fact that I went heavy on everything... but my shoulders weren't happy jumping straight to very heavy like that, so I may avoid that in the future. I might try it next week on chest and start with incline dumbbells and see how those work with that.
Doing legs today and Back tomorrow, I may try it with back and see how that works. I think starting on the flat bench with it just didn't work for me, but I can see how it's a good pump. It's almost like doing negatives.
It really throws your system for a loop.
Maybe you should do a more extensive warmup routine? Right now my heavy is so low that I'm not overly concerned with injury.
But it is nice to get under that heavy weight while I'm still fresh.
here's an example:Flat Bench:
Warm up to working set (for example):
10 x bar \ 10 x 50 \ 8 x 100 \ 8 x 125
8 x 145 (rest 3 minutes) \ 10 x 130 (rest 2 minutes) \ 12 x 120
of course on your heavy you really wanna do 4x275 then 6x260 then 8x250 or something like that
