15 Sadistic Xbox One Achievements Only Hardcore Gamers Unlocked

8. Run The Day - Xbox Fitness

Easily the most physically-tasking achievement to earn on the Xbox One, Run the Day requires you to earn 5,000 stars in Xbox Fitness, the Kinect powered exercise game. That means putting down the controller and putting your body through hours of workouts. For one workout the most stars you can earn is 5 stars, so you're looking at a MINIMUM of 1,000 workouts.

Your body might hurt to even think about that. On top of that, you're looking at more than 100 hours to gain this if you're exclusively doing the shortest workouts. If you ever needed the motivation to get into better shape, why not let it be the precious 100G for unlocking the achievement.

If for some odd reason you feel compelled to go for this achievement, you better get a move on because Microsoft is actually shutting down Xbox Fitness. As of July 1, 2017 Xbox Fitness will no longer be available, even to those who have purchased workouts - that's gotta hurt. Come next year those with this achievement will not only own the most physical Xbox One achievement out there, but one that others cannot possibly earn ever again.
