Lately I've been really bored at the gym, and almost unable to stay on a machine for more than 10-20 minutes. So, I've created a new routine...10 minutes warmup on the elliptical, three weight exercises, 10 minutes on another machine, three more weight exercises, and so on. On days I'm only doing cardio, I break it up into 6-10 minute sessions.
Not only has this helped with the boredom, in the last two weeks, my body fat percentage has dropped two percent!
