Advice for exercising a little everyday?

I want to exercise a little every day to make progress on building muscle. I am currently mobile, but lead a largely sedentary lifestyle due to a disability.

I would like advice on how to make sure I do enough to make progress, but not too much that I get very sore the next day and have to break the habit to recover(it takes me a lot longer to recover from sore muscles than others).

Is this possible and does anyone have advice on how to hit this sweet spot? I'm most worried about doing too little.
