Sit-Ups: Week 1 - Workout 2

rest 60 seconds between each SET (longer if required)
set 1	15
set 2	18
set 3	15
set 4	15
set 5	max (at least 18)

I wasn't able to finish this workout. I really struggled with the last couple of reps on sets 3 and 4. I decided to rest 90 seconds before the fifth set, but still was not able to get 18. I maxed out at 13 :/ I will re-do this workout in a couple of days.

Total Sit-Ups = 76
