I am new here and I'm interested in getting a bicycle. I don't know which to get.

Here are my stats:

Female
5'2"
190 pounds (need to lose the weight)

No heart problems (just had a life test done)
High chloresterol

Like I said, I need to lose the weight and get into shape. Any advise would be greatly appreciated. Oh! I just joined a gym and do strength training with a trainer three times a week. I want to do more.

Thanks!
