Fitness improvements and suggestions

I love all of these ideas. But I would be over-the-moon happy if they would just add in walking as an exercise. To include walking with others (maybe by the grouping action) or as a club activity. I would love to see this added for child thru elder and include pets with multiple people (not just one pet, one sim but I understand why they may not want to go back and alter that). This would be a great family activity as well as a non-strenuous exercise for our elders. And not necessarily a "speed walk", just a stroll through the neighborhood, like with hiking in Snowy Escape.
