Well, at least you get your 500 minute trophy!
If there was a 750, someone would probably post "I wish there was a 600 trophy".
Since you're close, and you want this, work on it! Add 10 minutes per day of something, anything, to your fitness. That will add some 300 minutes to your month - and pop you right into 1000 minutes for that trophy! :)
