Dogmama has the best advise...go get yourself a new toy. Nothing like the feeling of a new toy to motivate you into using it! If spin classes are too agressive, get a video and a trainer, spin at home. I loved spinning back into shape the one time i did it as i could still ride with all my riding buddies, but they couldn't drop me! Maybe invite a bunch of people (men and women) to grab a trainer and come spin in your basement on some really cold snowy day...
