Usually ones thinks of the Internet as encouraging you to sit at your computer for hours on end, turning into an amorphous, overweight, lazy blob of jelly, much like the adults in the movie “Wall-E”. But not so if one has the FitBit Wireless Activity Tracker (get that? Activity Tracker, not just a pedometer) – and particularly if one also pairs it with the FitBit Aria Wireless Scale. In fact, with these two devices together, you basically have an Internet personal trainer – one that, with apologies to the Police, is with you every step you take and every move you make. In fact, it will even monitor your sleep patterns for you, if you like!
