I think if you mix up the volume, intensity and what you're doing(same shit all the time, fuck that) then you should be able to workout every day no problem.
Like for me, I have my weights/strength day, then conditioning(complexes, cooper test), then a sled drag day, a ruck day. I don't do all of these at a 1:1:1:1 ratio or anything, but usually at least once a week unless something keeps getting in the way.
If things go perfect its hard day, easy day, hard day, easy day...
As long as you don't lose interest, stop progressing, or get injured then go for it. If you feel that something is getting fucked up, then reevaluate things. Like right now for me, I've neglected some shoulder mobility work, and the other day dips, which last time I did them, like 4 days before this time, they didn't hurt at all, but the other day something just felt wrong, and lo and behold, my sleeper stretch was utter shit. So now I'm going to do that in place of the pressing for the time being. Keep things dynamic and keep adapting.
Sorry for the longish rant.
