Hi Jennifer. Welcome to Work it, Mom! Don't feel bad about the exercise thing - 7 months is not long at all. Many of us (ahem, ahem) take much longer than that to start getting back in shape. Anyway, I'm a moderator here at Work it, Mom! Please give me a shout if you have a question or comment. :) Here are a couple groups you might like to check out:
