They make stationary bikes that fit under a desk. I've never used or seen one, but they exist. I considered getting one during 2020, but they seemed impossible to source.

they make walking pads as well for the desk; I've never used one but have seen some people who seem happy with them

		I have a coworker across the country with one. The level of walking that is compatible with an actual conversation on a video call is: slow stroll. That's better than what i'm doing, hunched over my desk with the metabolic rate of a sleeping lemur, but...it's a slow stroll.
