Primary Muscles

A suspension-based isolation exercise that mimics a dumbbell fly motion, emphasizing chest and shoulder engagement through an arcing motion.

Instructions

  1. Anchor the TRX straps at mid-length.
  2. Face the anchor point and grip the handles at chest height.
  3. Walk your feet forward to achieve the desired angle—more horizontal for harder resistance.
  4. Position your body in a slight forward lean with arms slightly bent.
  5. Keep your core engaged and your body in a straight line.
  6. Perform a fly motion by opening your arms outward and downward in an arcing path.
  7. Feel a stretch across your chest and shoulders at the bottom of the movement.
  8. Use your chest and shoulders to bring your arms back together in a controlled arc.
  9. Repeat for the desired number of reps.

Tips

  • Maintain a slight bend in your elbows throughout—this is not a straight-arm movement.
  • Keep your chest high and avoid excessive spinal extension.
  • The arcing motion should be smooth and controlled, not jerky.
  • Adjust your body angle to modify resistance—more horizontal = harder.
  • Focus on the chest contraction at the top of each repetition.

Recommended starting values

Sensible novice starting points for each goal, for a lifter aged 25–40. Scale down for smaller frames or older lifters. Treat the first set of any session as a discovery set.
