IRONPACK

TRX Chest Fly

Muscles worked: Chest.

How to do it

  1. Face away from the anchor with a handle in each hand and lean forward.
  2. Start with your hands together in front of your chest, elbows softly bent.
  3. Hold that soft elbow angle throughout - it must not change.
  4. Sweep the arms wide until you feel the stretch across the chest.
  5. Bring the hands back together. Start with a shallow lean - this one bites.

Coaching cues

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

Logging it

IronPack suggests working in the 8 to 12 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.
