Aaron Marino of alpha m. gives suggestions about what to do when you don’t feel like doing cardio. His ideas include breaking-up the monotony and movement.

He shifts machines: 10 – 15 minutes on each machine (treadmill, elliptical, bike, stepper). By breaking up the monotony and movement, you are giving your body rest and reducing your risk of injury from doing an exercise over-and-over. You’re getting cross trained too.
