Interesting. Can you elaborate?
Great point. Bodyweight is another good option. Drew Baye wrote a book called Project Kratos, which is a bodyweight HIT workout he’s been refining for the last decade or so.
One of my favorite HIT trainers , Skyler Tanner, is an exercise physiologist in Austin TX. He spent a year doing Kratos and had good things to say. Drew Baye isn’t polished, but he’s been an HIT trainer for several decades and really knows his stuff.


You would have to be out and out careless, methinks…
