I'm motivated more at the gym even though I do some work outs at home. if I pay the money for the gym, I'm definitely going to get my moneys worth
Try to get specials. SOme gyms may offer special rates for people working with a certain company or maybe even student rates. I pay $25 a month with no contract. There aren't many gyms here but I'm sure you wil have better luck. Also, try a trainer for a month that way you can learn how to use the machines and that way you can be even more motivated. Good luck!!!
