Do sports; there's bound to be something around that vibes with you. Team sports might be a good motivator, or things like boxing / martial arts. If you prefer to be by yourself, walking/running/cycling are options if you can get over it being boring (get good rain gear and put on a podcast or audiobook if it's too boring for you). It'll be good for your mental health as well to do an activity outside of work entirely.
How much time did your commute use to take? Take that time to spend on yourself. And what else do you do in your spare time? See if you can combine that with exercise. I mean if you spend an hour watching netflix or whatever, you could get a static bike and put a tablet on there. Just make sure to get a sweat on, it should be an active activity that gets your heart rate way up.
