In previous years, I've had a major problem keeping myself entertained for the duration of my gym time. Music definitely helps when I'm constantly moving from machine to machine. But when I'm running on a treadmill or Elliptical, I'd completely lose my motivation. Almost to the point where I just wouldn't be excited to go anymore.

But for the past 2 months, I've found that watching movies while running has rejuvenated my gym fun. I rarely get a chance to watch movies these days, so there's a huge backlog of movies I still have yet to watch on my computer. So I've been loading them on my iPhone to watch during my runs. By spanning them over several days in 20-minute segments, it's kept my attention span not only the duration of my run, but also between visits to the gym.

To convert my movies I use HandBrake 0.94, which has presets for every Apple product.
