My TrekDesk is well designed, well made and really useful. I accept that others may want to get their exercise working harder for shorter periods running or playing games (so did I when I was young), but at 58 years old, this is perfect for me. Most of the things I love to do (working and playing on the computer, reading, etc.) I can do on the TrekDesk while walking. In two hours (walking briskly) or three and a half (walking slowly) I can work and get all the exercise I need to firm up and (slowly) reduce my weight. I have stopped taking my blood pressure tablets - what more need I say?
