Mini Excercise Bike
I got this for my wife at Christmas. She's been using it every day for a week now. Normally she won't maintain any physical regimen for more than a day or so but she really seems to enjoy using this and claims that her walking and balance has improved as a result. The movement is circular, natural and no impact so I have no concerns over safety. Of the many such devices available out there, this is one I would recommend . One of her friends already intend to buy one.
