I just started one yesterday. I got on it for 35 minutes yesterday, and then for 45 today. And I plan on doing it five times a week. I just want to know if they actually work. I don't want to waste my time on something that doesn't. I feel the burn, but I don't want it to be me just hoping that it works, and making myself feel something that's not there. lolol ...Does anyone on here use one?

If your heart rate is accelerated and your body is moving, then, yep, you're burning calories and giving yourself a cardio-vascular work out!

I love to ride my stationary bike. I put in my scrubs dvd and go for it Personally, I don't want to build up or shorten my thigh muscles, so I keep it on the the lowest resistance (it's a magnetic bike) and pedal quite fast. If you want to tone your butt and thighs you can vary the tension and feel that burn! I really like the effect on my thighs. I'm sure you'll get a lot out of it, Starburst1987.
