I would go with a treadmill bc you can do more things on it.
yeah, I'm a treadmill person too. Spin class is evil.
well i don't like spinning so i would buy the treadmill. but that's just me.
I'm team treadmill! I have one and my roommate wanted a spin bike but I think the treadmill was a better investment because you can run of course but also walk whereas on the bike, you just bike your little heart out!
I have been trying to decide between both of these as well and I am not sure which I want to get! xx
treadmill, then you can do fun things like putting the dogs on it.
I like what Elizabeth said...worst case, with a treadmill you can use it to exercise the dogs. :)Maybe get the treadmill...If you can change the intensity (hills and speed, etc), you may be able to use more.
oh, those are big decisions! I'd personally go for the treadmill, but that's because I've never figured out an exercise bike :/ Good luck deciding!
