Wallerbear!
SURE rolling is great!! Way to go for just starting this journey!! And don't be too dismayed, I have friends who did the fit test and ended it with their heads in the toilet b/c they were either going to puke or pass out. Stick with it, do your best, take breaks as needed, and before long you will notice yourself getting stronger each time you do a workout.
Great job my friend,
