Hello Shoulders Workout

Pre-Wod:
3-5 rounds warmup, increasing weight: 1 Press, 1 Push Press, 1 Push Jerk
65, 75, 85, 95, 105

WOD:
12min AMRAP
3 Muscle Ups (or 3 Pull Ups + 3 Dips) (I did Pull Up/Dip combinations)
12 Push Jerk (115/75) (I stuck with 75 the whole round as this is day 3 of CrossFit for me)

Post-Wod:
100 ABMAT Situps as fast as possible, but not timed.
