I'm also 5' 2" and my highest weight was 190 in the summer of 2008. Since then, I'm down to 167. However, this is my year! I turn 50, and I'm determined to be Fit by Fifty!! I just stared on the Jan 18 with my exercise routine: X-Fit class MWF, Cardio Kick boxing T/Th, Karate, and jogging a couple of times a week. It sounds like a lot, but it's great! I'm excited to be physically active.
I know last year I wanted to try some things at home. I bought two or three of the Biggest Loser DVD's and that's how I initially lost the first 20 lbs. You can get them at Wal-mart for less than $10 each, and you can customize your workouts. Also, you can buy a set or two of dumb bells or even the exercist bands with handles...they're pretty cheap. For cardio, a NordicTrac ski machine is great. You can usually find one cheap, since people get one and use it for a clothing rack for while, then want to get rid of it! There are lots of inexpensive options without buying big equipment. I agree with the person who said to walk first. George Foreman has a walking DVD you can do indoors and it's a great calorie burner.
