If Rayman takes 10 hours doing his workouts, half the number of hours junior takes, then Junior takes 2*10 = <<10*2=20>>20 hours to do his workouts in a week.
Altogether, Junior and Rayman take 20+10 = <<20+10=30>>30 hours doing their workouts in a week.
Wolverine takes 2*30 = <<2*30=60>>60 hours to do her workouts in a week, twice the total number of hours Rayman and Junior takes.
