40 V-Ups 

75 Calorie SkiErg (5:47.9 // 1273m)
40 Med Ball Sit-ups (10#)
75 Calorie SkiErg (5:47.0 // 1273m)

As written by Misfit Athletics, this is 50/40/30 GHDs interspersed with 100/80/60 calories on the SkiErg. There is no GHD at WC YMCA so I did my best to maintain the stimulus of taxing my midline with hip driven movements.
