Lifting heavy 2x a week doesn't have to mean a drawn out session. It can mean two balls out sets (1 heavy, 1 light + rest pause) to failure. All in all this takes maybe 15-30min a week to do, and can still drive linear progress week to week. Surely, you have 4 hard sets a week in you, right?
Every other day? Conditioning. Possibly multiple times a day if energy and time allows. The body has enough parts to where you shouldn't ever have to reuse the same worked section 2 days in a row.
Example
1)Heavy press: floor press
2)conditioning: pull, swing, calves, tibs, lunges, squats, single leg rdl
3)conditioning: press, (ditto)
4)Heavy pull: power clean
5)conditioning: press, (ditto)
6)conditioning: pull, (ditto)
Rest or repeat
Press = calisthenics presses. Use down, Juarez, straight sets, emoms
Pull = sandbag row. Normally this is a good place for calisthenics pulls as well, but that shit aint serving me at the moment.same type of rep models.
I list a ton of movement patterns after press/pull as a potential grab bag. Use whatever isn't tired. If you are going back and forth with dip Juarez valley and seated calf raises, guess what. The calf raises are your rest periods. They're filler episodes.
