I will go against the grain a bit and offer an alternative.

Do you have space for a home gym? Gym equipment is expensive but $200 a month adds up pretty fast and certain gym equipment can be had very very cheaply on the second hand market. People are giving away treadmills in the spring but they can and do break but stuff like barbells, racks, and weights are steel or iron and will pretty much last forever.

I was at this point and decided that I invest in a home gym. I did it slowly and until I got certain pieces of equipment I felt very limited in what I could do. But after about a year I have what I need and I got most of it second hand for pennies on the dollar.

The best part is them other then cardio stuff most gym equipment holds value very well because I got such good deals I could probably sell this stuff and break even or make a bit if I was patient.
