I doubt I'll have luck convincing anyone, but Monster Hunter Now might accidentally be one of the best games you can play for health.
Both it and Pokemon Go are games that encourage you to walk, but #MHNow requires you to plan, strategize, observe, and learn.
The game does have some #F2P stuff, but spending money only saves a bit of time (~15 minutes to regen health). MH is a skill game (I call it "Nice Dark Souls"). You still need to hunt and gather to acquire the materials needed to advance.
