My iPad has been a godsend for my exercise routine. I buy the BluRay discs with the extra digital copy included, and I load those on my iPad. I only watch those movies when I work out, so if I want to get to the end of a movie, I have to go work out!
I also download books & magazines on my iPad and read while working out as well. Just when I do the bikes…not the treadmill! LOL
