Funny. One of my cousins wore ankle bracelets also. She finally qualified. Unfortunately I qualified legally :-) I'm 5'7", weigh 241 and have high blood pressure.
I've always been overweight but I've been this height since I was 12 so that helped me hide it. I ran track from 7th grade through high school. So when I stopped running and went to college, my weight ballooned from 175 to 240 by the time I graduated. I managed to maintain around 225 for about 6 years. Then I tried Weight Watchers, got down to 197, stayed there for two years. Then I moved to another state, got out of my routine and hit 256 for the first time.
So I'm going to do my best to lose some weight before my surgery. I've already started exercising three times a week.
Good luck to you!
