Disclaimer: There are people much more experienced with TM than myself.
For light squats, even front squats, I’d stick w/ 2x5 over 3x3.
I would also DL on volume day, but you’ll have to play w/ it to figure out what works for you.
I wouldn’t do any assistance at first. After you get used to it, maybe back extensions, 5 x 10, and chins, 3 x F, on your light day. After that for a few weeks, and you still have the work capacity, then look at swapping in something else.
I wouldn’t do any rowing for the time being. If you want something from the floor, I’d power clean on intensity day, 5 x 3.
The percentage on your volume day doesn’t really matter that much, because it’s just a starting point. You only increase weight on the volume day if your intensity day isn’t progressing. The entire program is pretty much centralized around driving up your 5RM on intensity day.
