I think for what your option are youre in good shape. There are gyms in my neighborhood that charge anywhere between 55 and 200 bucks/month. What r u nuts????? Fortunately, I work in a hotel where I can train for free. Also, I belong to Cardinal Fitness for $19/month. If I go onle once or twice, who cares, ya know....
If you have a bike at home, look into one of those things that elevate your rear wheel so you can do your cardio.....
