I also bust my butt with a training split like Ambrosia, except it's a bi-week, 3x/week cycle. First week it's upper body weights-moderate cardio-lower body weights. Second week it's HIIT-Total overall circuit weights-HIIT, then repeat. Yeah, sometimes I skip one or two for unpredictable excuses, but I get back and resume the next one. I do them at night, knocks me out like nature's heroin, swear to god!
I work out at night too, but just because I'm not a morning person Does the opposite to me. I can't do it to close to bed time because I get too energized. I'm already a night owl, and have a hard enough time going to bed.
