How about Kettlebell training ?
It can be done easily in your home (if you have some space) and you can do great full body workouts. I was pretty much out of shape when I've started it two years ago and now I feel great.
The people over at the Kettlebell subreddit are quite helpful: https://www.reddit.com/r/kettlebell
The FAQs show some good starting points https://www.reddit.com/r/kettlebell/wiki/index
Maybe this is something for you. Altough some people around Pavel (and Strongfirst) can come off a little bit cult-ish, but I don't think that it is too bad.
