Sorry I'm new
How they work is as a motivatonal tool. They're not actually worth something you can cash in or aught. You get them from doing workouts. The harder, ( intense ones) and longer you do them for ( like some of the ones I and others do are over an hour long), the more points you get. On the Skimble website you can see exactly how many you've got, how many you earnt this month, how many your followers/ dudes you're following got, and, even, how you are ranked in the world for that month. So, get working out, vet arming points and have a heap of fun. All the best.
