Doing 50 minutes of cardio output training can feel like an eternity. I find it helps to mix it up by using different cardio machines or going for a 5-mile jog outside. A slight change in scenery or a killer playlist can make a long steady-state session feel less laborious.
In the context of a 24-hour day, 50 minutes really isn't that long. Keep your perspective positive and enjoy this time to focus on yourself, your body, and your continually improving physique.
