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 1 kg jumps when you own the top of the range. Bodyweight movement: log added weight only, and your records account for your logged bodyweight. Records are tracked automatically at every rep count from 1 to 12. Check your estimated 1RM from any hard set.
