I suppose. I've just always had access to a gym, my mom works in fitness so it's pretty much free for me.
Or you can do low-budget house workouts. Put your feet under furniture and do sit-ups, push-ups are easy, do curls with milk or juice cartons (drink until their the weight you want). That's a little extreme, but it does get the job done.
The best cardio IMO is biking. It's more fun that running, and you get around faster, and it can be used as a practical form of transportation most times.
