50-40-30-20-10 reps of:
double-unders (double the volume with singles)
35lb unbroken kb swings

Notes: I wanted to do something quick and I saw this one on @thedavecastro Instagram. It takes the Annie template and replaces sit-ups with swings. Challenged myself to go unbroken on the swings after seeing the same in Castro's post and was able to hang on for the entire workout.
