If you could only buy one piece of cardio equipment what would it be?
I own an elliptical, a gazelle,a cardio-rider and a weight bench. I love my elliptical....hate the cardio-rider and find the gazelle just so-so. I have thought about getting a excersize bike(though not sure what kind since there seem to be several), but someone else said I should skip it and get a good treadmill. I have used a treadmill and like my elliptical better.
I eventually want to join a gym, but time and money are a factor right now, but I get so bored with just my elliptical, but don't feel my other two work as well. I would like to be able to switch on and off between machines.
So what does everyone else have/like, and is one more effective then the other?
