Hi Rebecca... Michele here.
Congrats! First couple steps accomplished! You are on your way! I started (some time ago) with just 10 minutes at a time. Just be happy and proud of yourself for that for the first week or so, then just add 5 minutes per workout for the next week or so, and continue like that. Once you bump into the issue of "can't add ANY more minutes!" due to lack of time (which I totally understand being a single mom of two teenagers and working full time), then you can bump up your workouts with intensity. Maybe you walk five minutes, run two, or add some hills or something like that. Before you know it, you'll feel like superwoman (which you are)!!
Enjoy the journey and really notice how much better you feel after your workouts. I really had to pay attention to that. I'd be so fatigued I wouldn't want to go workout, but I promised myself that I'd try at least five minutes and if I wasn't feeling at least a little bit better, I gave myself permission to stop for that day (because you never know if you are fighting a bug or sick or whatever). I find that at least 90% of the time I feel much better after a few minutes of activity, and really feel awesome after about 30 minutes of heart pumping activity. If I didn't pay attention and make sure I remember that, I'd probably just give up when I felt exhausted. So, just my tip... notice all the wonderful rewards of what you are doing.
Plus one more tip... I've also lost weight (33 lbs and maintained for a couple years) - make sure you are not just measuring your success with a scale. Take your measurements. Notice the tone of your muscles. As you add activity you build muscle. Muscle does not weigh more than fat (a pound is a pound no matter what!), but muscle takes up a lot less room. So, you may have success with the tape measure even when you see nothing on the scale.
