I am not sure to understand.
Roc will be creating a fitness program that has 'skill levels' in a similar way to Eve. To begin the next 'skill' routine, you first have to 'train' the required skills by completing an easier routine.
In a very very basic example, it might look like this:
Pull ups lvl1: 10 pull ups
Pull ups lvl2: 15 pull ups in 2 minutes
Pull ups lvl3: 20 pulls ups
etc
etc
(For the record, I have no idea how to set up a routine, so please don't take that seriously ._. )
