Hi Aimee - We bought a treamill back in late spring and my 10 yr old has been using it pretty faithfully since the end of August. He has always had low energy and is’t what one consider athletic at all. Definite couch potato!!  :) We just recently put a TV in front  of the treadmill along with some wireless headphones so that he could be "entertained" while exercising - it worked. He never even minds walking now and is up to 45 min at 3.5mph - not bad for a couch potato! Like Danny, we have the Tae-Bo tapes also, boy - he is not kidding! Talk about tough! I’m up to about the 8 min mark too, Danny! My son actually likes joining in on occasion and I just saw where Billy Blanks has a kids Tae-Bo tape. I think that will make it under the Christmas tree! Bottom line though - he has actually lost a couple of pounds and his energy level has definitely increased - all from the walking! Thanks for sharing Aimee!
