I bought an elliptical!!!!!

I had been trying to decide on if I wanted to get an elliptical of a stationary bike. I have knee issues because of my arthritis and I have also had other issues with torn ligaments due to step aerobics. I wanted something that I could do here in my home. I looked at several different versions and looked at prices also. I didn't want to spend alot of money at first. I finally decided on an elliptical that was at Wal-Mart. It was around $268.00 and was just what I needed. It has 8 different workouts that I can program in and will change from 12" to 18". It is not all that bulky and fits nicely into my living room. Not to mention that it is quiet. My hubby and I put it together last night in about two hours. Probably wouldn't have taken as long if he had listened to me reading the directions and if I hadn't put something on backwards. :-) I got on it this morning, turned on the music channel of my tv, told the kids to move back and proceeded to get my butt kicked. Did I mention that I only lasted 5 minutes.....by the time I got off my legs were like jello. I am going to try again in just a bit and my goal is to work up to 15 minutes. Setting the goal low so I don't disappoint myself. Hopefully withing the next couple of days I will get up to 30 minutes, but I will take any exercise compared to none at all.
