BEST $$ I HAVE SPENT IN DECADES - I'LL NEVER GO BACK TO SITTING! I am in my 50's now and I work from home, so I knew that sitting all day was quickly aging me. It seemed I could never get to the gym on most days. Plus, even if I squeezed in the occasional workout, it was offset by 7-9 hours of sitting at my desk, and my energy was dwindling. This new TrekDesk has changed the way that I look at my work and my life...as well as my LIFEstyle. It's so easy and natural to use the TrekDesk with my treadmill, and I'll never go back to sitting all day. This is the best $$ that I've invested in myself in a decade. Thank you Steve & TrekDesk team!
