Should undulate with your goals. 10k steps a day seems to be a reasonable and meaningful goal for baseline health and it’s what I try to hit when in a growth period. 10k steps for me personally is about a 20m walk + my normal daily activity.
After that, depends on the goal and I think in general most people would benefit from a combination of HIIT and LISS anyways. Sprinting is about the most athletic thing you can do and I’d bet <1% of the population moves in any form of maximum exertion at any point during a standard week.
Long way of saying get a baseline level of movement for health and use added HIIT and LISS as needed.
Me personall:
Offseason: 4-5x20m walks a week
Prep: as high as 120m of LISS 6x a week depending on the need
