You can take the Sim into CAS and ‘push in’/re-shape areas of their body that have gotten fluffy.If your Sim is energized you can click on the floor and direct them to do exercises.Otherwise you could download one from the gallery or build one. There’s a gym in Willow Creek and one in Oasis Springs. Have your Sim go to the gym and workout.Then then I can tell them to watch a channel they learn from (like cooking), and at its best this method results in two sims jogging, learning cooking while losing weight, socializing, and having fun (due to the TV). I also go a step further if I have space. They socialize then and are more likely to enjoy the jog. I place two treadmills side-by-side if I can.
but I though I'd mention a couple of tricks I like to use. The treadmill is my go-to, as was already mentioned above by others.are some of the things I've tried in addition to sending them jogging (I had trouble with my sims stopping when they wear out of shape and not sticking to jogging) and the things mention having to do with food.Information, Guides and Announcements for the EA app.
