Do your sims exercise?

Although I only really worry about my sims exercising when they start to get a bit on the hefty side, I do try to get them all to a base of fitness 4-5 before they age up to YA if I play them through their teens. I've noticed they're more inclined to excercise autonomously that way, even without being energized.
And I do love the sparing bot. I haven't noticed if the Spar interaction (as opposed to the practice fight interaction) is available outside the military career. If they haven't, I hope they free that one up (or maybe add it to a sports expansion pack for Martial Arts) at some point and make it a fitness action. The animation is really well done (especially when both sims have fitness 10)

Usually my kids are fat when they grow up, I find especially toddlers hard to feed in a way that they don't gain weight. So once they grow into a teen I usually make them exercise some of the weight off, after that they can keep the shape I want with just watching what they eat.

It depends on the sim really. If it's a usually slim sim that's gaining weight then I will make efforts to keep them as they were originally. If a sim was already carrying a bit of weight originally then I leave them as they are. Other than that I have my active sims exercise cause they enjoy it or maybe just for a career requirement.

I used to love having my sims visit the gym but they all started getting really muscular which I didn't like so I stopped with regular gym visits.

It depends on the Sim. Active Sims always exercise. Also if a Sim looks fit then I make her/him exercise. Sometimes a Sim decides to have a new hobby and start exercising.

I play rotationally, and have an extensive rotation, so it really depends on the sim, but since I have a few that have put on extra weight, I have set them up jogging to keep the weight off. I have some sims who are active, and/or in the athletic career, that like working out. Others work out mainly for their job ((like my astronauts). I have several sims that love dancing. Some like to play sports (basketball), I wish we had more sports. I have an athletic sim that wears a baseball outfit sometimes, and dreams of mitts. I wish they would bring out a mitt and baseball clutter objects for shelves, dressers, or bookcases. The big sports object (with bat and stuff) on the floor takes up so much room. I also wish you could play catch with a friend or a child. One or two sims do yoga or meditation, some swim. My military sim spars and uses the kickbox machine. A few of my more buff sims use machines at the gym. So, really my sims are all different when it comes to exercise.

My sims that exercise also tend to eat healthier.

I have some health issues that make exercise really difficult so I always forget it's a thing lol! So most of my sims only do if it's for a job or their personality or environment influence them to do it on their own. My Legacy family didn't exercise until I had a few of them pick the goal of losing weight for the New Year and now even after a few of them are still interested on their own it seems

Mostly, but if I want some specific sims to stay unfit I dont exercise when playing them.

My sims only jog if they're taking their dog out for a walk lol

If I don't get mine an exercise bike or similar and make them use them they tend to do press-ups without warning! It must be my choice of traits!
