Elliptical Or Exercise Bike?

Elliptical, hands down. I love mine! It burns more than the exercise bike, too. (At least I'm pretty sure) Anyway, check Craigs List and things like that, because you can usually get a good deal on stuff like this. Good luck and happy exercising!

If you bike in the summer I would go for the bike to improve your performance. If you don't bike, I would go with the elliptical, as you get a better burn as you are not seated.

Definitely elliptical!

If you get a spin bike, you can buy various DVD's to workout with. You can burn more calories with interval training and using multiple DVDs will give you a nice variety.

My preference is the elliptical but, I suggest you do what works best for you.

Elliptical...cause you do burn quite a bit...unless your planning on standing while riding your bike...lol, I only do those during my classes..otherwise I'd just sit and pedal...

I have an elliptical. I really like it. But now I want a recumbent bike.

I had a recumbent bike. It didn't work for me because my butt kept going numb. I'm not sure if it was cutting off circulation or sitting on a nerve. It happened at the gym, too.

ELLIPTICAL!!!! This is what I bought when I started my journey. And just like you, I already had a treadmill.
I fell in love! It is very challenging at first that's for sure. But once you get the hang of it, it's great!

Just some advice. an elliptical is a great calorie burning piece of equipment, especially when compared to a bike.
HOWEVER, nothing beats running on a treadmill! My treadmill is broken right now and I can't wait to get it fixed for this reason. It's all I hear about.
As most runners will say, it's the best way to burn calories and shed weight.

If you do decide on getting a elliptical, just make sure you get one with a good stride length. And resistance is a good idea as well.
My friend bought a elliptical but didn't pay attention to the stride length. Now it no longer challenges her muscles and it's far too easy.

Hope this all helps! Take care.

A treadmill, elliptical and bike all work essentially the same major muscles. So all three are very similar in what you're exercising in your body. If it were me, I'd get the bike because biking is a common cross-train for runners because they strengthen the same muscles so they benefit each other, but the bike takes you off your feet. This creates a larger difference in how tour body recovers between workouts. Despite an elliptical being super low impact, it's still a body weight supporting workout. Which means that if you have a injury that prevents you from running you're more likely to have more benefits from having a bike to turn to instead of an elliptical.

And don't discount calorie burn on a bike. If you have an upright one you can get some spinning DVDs or just work intervals yourself. This can mean standing on the pedals and getting your butt off the seat to push stronger and harder. Plus, if you build up a good strength with a stationary bike, you can look to move that outdoors and be able to enjoy riding on trails and around your city, the elliptical doesn't give you that transition.

But if I had the option of anything to add to a home gym, I'd go for some free weights, dumb bells and a bar. Strength training will build muscle, help lean out your body as you lose fat, help your running and give you overall better body health.
