I play FitXR which has HIIT and I use resistance bands that I connect to a belt, so I’m adding plenty of strength.
Plus I’m not a Gym rat, I’m not trying to do what you are doing, I use it because I hate going to the gym, i hate any exercise, I want to be able to do something at home on my lunch break and most of all it really makes me feel great for the rest of the day, it’s the best thing I do for myself so I’m not sure how it can be a ‘remarkably poor allocation of time’ it’s literally the opposite of that, i do it for an hour, my heart rate goes way up, I sweat a lot and I’m buzzing for hours afterwords with a great amount of focus. Your comment is complete and utter nonsense.
I don’t care about ‘training’, I care about exercise. Your post makes no sense. Nobody doing this is trying to become some brain dead nobody builder like yourself.
