I was on here asking questions about treadmills not that long ago too. I have a bad knee and I wondered how it would affect that. I also wanted something with resistance like @weightlosshopeful said, I think the incline setting helps burn more too. @Follena FWIW I ended up taking the plunge and it's been a great thing for me! I refuse to watch TV now without at least walking on the treadmill while doing it. Just make sure you do your homework before you buy. I read up on this one
https://www.treadmillreviews.com/nor...eadmill-review and it has been great for me. Just make sure you read and get one that is in your budget and will help you reach whatever goal you set for yourself.
