I think it might help to actually formulate a goal, like, say, run 5K or bike 100 miles or do 100 pushups at once or something, and then build a workout regimen that will get you to that point. In my own experience, I've found that "I'll just do pushups and stuff" means I won't stick with it, because it's difficult for me to really measure progress and I get easily discouraged without a training plan. What sports or fitness celebrities inspire you? Have you ever watched American Ninja Warrior or anything like that? That's one of the things that inspires me on my fitness journey. I'm primarily a runner, but I cross train with strength and climbing as much as I can. I still can't do more than two pull-ups, but someday... As for resources, /r/fitness and /r/bodyweight on Reddit have a bunch of decent resources. The latter is especially useful because they can provide some really good routines that incorporate only yourself, so you won't need equipment or anything else. If all else fails, hire a personal trainer. Even in this COVID era, they can coach you over video call, and if you do that for a few weeks, you should have enough workouts to keep yourself busy on your own for a while. My final tip is to do at least 10 minutes of exercise per day. You can do anything for 10 minutes a day. If after 10 minutes I'm bored or I'm tired or I just plain don't want to continue, then I give myself permission to quit. (I've been doing this for years and i've never actually stopped after 10 minutes... the hardest part about working out is STARTING!) Anyway, good luck!
