MeritoriousG 60

This achievement required you to get all 50 available badges.

46 badges were available from all of the possible sessions for the 23 types of exercise (in Activities, Workouts and Classes).

4 other badges are earned by respectively:
* The Visitor - 3rd launch of the game
* The Regular - 10th launch of the game
* Feel The Burn - 30 minutes of exercise on a particular day
* Calorie Killer - 60 minutes of exercise on a particular day

So, where's the Discontinued part?

There's 3 types of exercise in the Workouts that are/were unlockable only through Uplay that is now discontinued in favor of Ubisoft Connect: Toning, Legs and Sports Preparation.

As Uplay is discontinued, there's a high chance that you can't earn or redeem the Units (Uplay points) in-game anymore. Though the rewards are still unlockable using Units in the Ubisoft Connect page: https://ubisoftconnect.com/en-US/gam...-2012/rewards/, though I cannot confirm that the in-game content will be available even when redeemed.
