Walking! Walking will slowly help build a base of fitness, and it's FREE. Plus it's easily adjustable, you can go faster or slower, further or not so far, and make it work for you.
Also, it's ok to start with 3-5 minutes of an exercise - that's more than you did before! When I first started exercising I was completely fatigued after using the elliptical for 5 minutes. The next time I used the elliptical I would tell myself "ok, today I am going to do 5 and a half minutes". I wasn't able to increase my time every single time, but I was slowly able to add on 30 seconds, and then full minutes. I remember being SO PROUD when I hit 10 minutes. Listen to your body, but also don't be afraid to challenge yourself, a little bit at a time.
Do something everyday that your future self will thank you for.
