The Workout

Kelsey explained in her caption that this workout should be performed as a superset, meaning you'll take little to no rest in between each exercise. Complete three sets of bicep curls and bent-over reverse flys, then complete three sets of barbell curls and bent-over rows. As always, don't forget to warm up before the workout and cool down afterward.
