How to do it

  3. Flex your hips slightly and allow the weight to hyperextend the lower back.

  5. Slowly return to the starting position as you inhale.

Coaching cues

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

Logging it

IronPack suggests working in the 10 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.
