Hi!
I do not have a FitBit, but I have a Garmin Vivofit and I LOVE it! Garmin has an app that can show you your steps, sleep, miles, and tracks your progress. Through the app (it's a free app), you can also 'challenge' people to see who can get more steps. The Vivofit also has a 'lazy bar,' as I call it, and it becomes red if you are stationary for a certain amount of time. I think it has helped me a lot; instead of staying stationary, I try to get my steps in.
As far as exercise, I do not know if you have anywhere you can walk/jog (even inside since it's getting hot), but there is an app called C25K (Couch to 5K), which I have used and loved. It is intended as an 8-week program to get you from the couch to successfully completing a 5K within 30ish minutes. Each week the walk/jog ratio changes, but it has verbal commands and walks you through the process (pun intended
). Truthfully, I have kept repeating the first week because that is still a struggle for me, so I do the first week when I go on a walk/jog.
Let me know if you have any questions! Good luck!
