When I was younger I suffered a serious back injury. Since then, it's been very easy to hurt my back, because I have arthritis. This has made it difficult for me to find a workout that didn't hurt my back. After seeing the Gazelle on TV, I decided that it would probably be my best option.
When I first got my Gazelle Edge Trainer, I found the workout so easy I actually worked out too much and pulled my leg muscles. After my leg muscles had healed, I was back to my workout and loved it. The Gazelle Edge Trainer is so easy to use and has never hurt my back.
The only problem I have with this machine is that it makes noise. After just a few uses it started making a squeaky noise. I contacted the compay and they told me to use a silicone spray on the joints, but this didn't work.
Other than the noise, this is a great machine that works all my muscles without hurting my back. If you have back pain, this is definitely the workout for you.
