March needs to be about exercising

Man, I feel so out of shape and gross.  Nothing makes me want to stay inside and eat carbs and butter like a Vermont winter.  I am really struggling to find the motivation to exercise though.  Honestly, for the most part, I hate exercising.  I mean, I love to ride my bike on the bike path in the summer, but that's months away.  I love yoga, but I haven't been doing much of that either.  I don't find that I get as much out of doing yoga at home.  I really need a class.  But you know, it's cold out...I don't want to spend the money...yoga pants make me feel fat...blah, blah, blah.  I have a membership to the YMCA, but I haven't been using it enough.  I'm basically just donating money to them.  I know that exercise would help with my whole "fertile lifestyle" though.  Also, I don't want to start out a pregnancy feeling all out of shape and gross.  So, March needs about exercise.  Nothing crazy, just moderate exercise.  I'm not looking to lose a bunch of weight.  I just want to feel active and in shape.  So, I want to get the most out of my Y membership this month and then cancel it.  Then, I want to get back to yoga.  Then, back to the bike path for the summer.  So, I'm just putting this out there to keep myself honest.
