We have a very simple pedal affair that you can use from any chair you like. My husband puts it in front of his easy chair and pedals while he watchs TV at night. For people who can't use it with their feet, it can be set on a table and used with your hands. You can set the resistance if you want. We've had it for years but I think you can still find them on the internet. The exercise is authentic; it will reduce his BP and his blood sugar by 50 points.
