I trained like that in 2021 - full body continuous workouts every other day. By the beginning of summer a female manager at work was like "wow, you are jacked". And I should have been - I was basically training like a pro athlete for months at that point.
Unfortunately, I fell off that routine when I moved later in the summer and I never got back to the same level of intensity. The best I've done since then is 1-2x/week. But I also did incorporate other activities which I've already discussed in that time, so it's not like I've been inactive.
But yes, my preference is full body workouts and as little rest between sets as possible. The only caveat is that it can literally be hazardous to your health if you're inexperienced. I think I first tried it because you discussed it on Black Pill Fitness back in 2018 and at that time I was not ready for it - I had to dial back the intensity after my heart started racing too fast.
