Hey, Schnitzle,
Welcome! A year and a half ago, give or take, I got on a bike for the first time in years, and like you, I am 5' 4.5", and at the time, I weighed 250 pounds. Now, I'm not really the typical TEr in that I don't ride miles and miles every week. In fact, because of injuries and family stuff, I haven't even ridden outside since October, and I've only been on the trainer a few times, but I love riding my bike, and I'm making up the road time in the pool, but thanks to the love, support, and education I've received here, I'm down 20 pounds and I'm so much healthier and in such a better place emotionally and psychologically than I was two years ago.
Look for the just-started March-April Weight Loss Thread (possegal will be posting it later this week since it's the first week of March). Add your current weight and set a goal and keep track along with the rest of us. It's awesome to watch your progress.
You can ask anything here. Anything at all. You'll get a supportive and informative answer. There is no flaming, no ridicule, no judging. This is the most supportive online community you'll find anywhere. I'm so glad I found it, and I'm sure you will be, too.
Congrats on the new bike, too. Post a photo!
