I've done every possible combination. HIIT, free weights, bands, VR cardio, lengthy strolls. I've done each for at least months at a time. None of have had any noticeable effects on my well-being. I live in a big city with no car, so I walk a lot no matter what. Even going relatively hard on barbell squats and dead lifts just made my legs feel weaker.
