Public Relations coach Judy Lynes walks on the TreadDesk while working at her desk at the Phelps Agency on Thursday, November 29, 2012. The Tread Desk allows you to integrate exercise right into your workday. By walking at only 1.0 mph most users can type and talk on the phone just like when sitting down, however they are burning an additional 100 calories per hour even when walking at these slow speeds. Lynes averages 4 to 5 miles per day on the TreadDesk.
