If one of your New Year's Resolutions is to get fit, consider trying it without spending money on an expensive gym.
Walking/Running (consider starting a neighborhood walking group)
Rent exercise videos from the library
Order an inexpensive video from Amazon (if you have Prime you can watch many of them free)
Waiting a few months and buying low cost equipment on Craig's List or from yard sales
Download Zova for I-Pad or I-Tunes
Look at videos on You Tube
Note: If you do decide to join a gym, carefully read how much money it would cost to cancel the gym membership. The YMCA might be a better choice.
