text: I know you said free, but if you get a subscription to a fitness magazine or shape magazine, they offer lots of tips on workout plans and it helps keep you motivated. I think they are only like $15 a year, so it's a lot cheaper than joining the gym.  You could also try a workout video like Tae Bo or Yoga Booty Ballet or Turbo jam which would really help you tone and give you some variety.  I know these aren't free, but they are good resources.
