Sportneer Portable Under Desk Pedal Exerciser - Low Resistance Folding Exercise Bike for Arms & Legs - Compact Indoor Cycling Machine for Home Office Workouts & Active Sitting

I'm in my 60's, am definitely sedentary and have back and knee issues, so it limits the types of exercise I can do satisfactorily without hurting myself. I really needed to exercise my legs more and this worked out as a good solution for me. My legs had gotten atrophied to the point of limping and having serious knee pain, so this bike pedal exerciser was perfect as it's good for beginners and the elderly. I can now do low resistance bike pedaling exercising indoors while I'm safely seated in my chair and can even watch tv while I'm doing it. This does require some assembly, and although it seems straightforward, I immediately got stuck on the very first step because the metal tubes wouldn't align and the screw wouldn't catch to tighten. After some initial frustration, I got a flashlight and looked down the metal tube, and the piece that you need to screw into had fallen inside down the other end, so once I got that figured out, the rest went much easier. I had a little difficulty getting the pull pin installed, but I just had to hold down the little nub to make it slide in, and I imagine I'll have the same issue removing it, but that's only if you want to fold the machine, which I don't intend on doing. The height and pedal straps are adjustable and it does have adjustable resistance, so you can set it to where you're the most comfortable. It has an LED display to monitor your progress with time, counter, and calorie settings and it comes with a small floor mat and carry strap. You can also do arm pedaling exercises just as easily, so you can strengthen both your legs and your arms with this one machine. It really is an affordable, convenient and safe way to get in those extra steps and strengthen your muscles, help relieve muscle fatigue and joint pain all while watching tv or reading a book in the comfort of your home.
