Basically i'm looking to buy a machine to do cardio in my apartment. I know running is the best, but i have a real problem with shin splints no matter what i do. Plus i live in pennsylvania and it get's pretty fu**in cold in the winter. I'd like to swim, but with my work schedule it is hard to find time to be in the gym with the pool is open for laps. So basically i'm looking for low to mid impact workouts. Walking around Dicks yesterday i came down to a few choices. Eliptical: I know they are good, but i just don't think i can afford it right now. Gazelle(with pistons): It looks like it MAY work, but i'd hate to buy it and it be a pos. Plus tony little is a freakin douchebag and i'd hate to put any money in his pocket(unless it works) Rower: I don't know much about them, but some people say they work well. But i need over all cardo, not just upper body. Any suggestions?
