How to do it

  1. Adjust the handles so that they are fully to the rear.
  2. In a semicircular motion, pull your hands out to your side and back, contracting your rear delts.
  3. Keep your arms slightly bent throughout the movement, with all of the motion occurring at the shoulder joint.
  4. Pause at the rear of the movement, and slowly return the weight to the starting position.

Coaching cues

The two cues IronPack shows on this exercise's card mid-workout:

Logging it

IronPack suggests working in the 12 to 15 rep range, progressing in 2.5 kg jumps when you own the top of the range. Records are tracked automatically at every rep count from 1 to 12. Check your estimated 1RM from any hard set.
