A pull exercise used in HYROX training.

The incline dumbbell reverse fly is a chest-supported exercise isolating the rear deltoids for HYROX postural endurance and shoulder health.

Definition

The incline dumbbell reverse fly is a pull/isolation exercise performed lying face-down on an incline bench (30-45 degrees). The athlete raises dumbbells out to the sides, targeting the rear deltoids and upper back. The chest support eliminates lower-back fatigue, allowing greater focus on the target muscles compared to the standing bent over reverse fly.

Technique & Form

  1. Starting position - Lie face-down on an incline bench set at 30-45 degrees. Arms hang straight down with dumbbells, palms facing each other.
  2. Raise phase - Squeeze the shoulder blades and raise the dumbbells out to the sides until arms are parallel to the floor.
  3. Lowering phase - Lower under control.
  4. Breathing - Exhale as you raise; inhale as you lower.
  5. Tempo - 2 seconds up, 1-second hold, 2 seconds down.

Muscles Worked

  • Primary movers: Posterior deltoid, rhomboids, middle trapezius
  • Stabilizers: Infraspinatus, teres minor

Common Mistakes

  • Using too much weight - Momentum takes over. Fix: use 4-8 kg and focus on the squeeze.
  • Lifting too high - Recruits upper traps. Fix: stop at shoulder height.

Benefits

  • Strict rear delt isolation without lower-back fatigue.
  • Builds postural muscles for HYROX® running and station endurance.
  • Balances push-heavy training programs.

HYROX® Context

The incline reverse fly builds postural endurance for HYROX® by strengthening the muscles that prevent forward shoulder rounding. Program 3 sets of 12-15 reps on upper-body days, pairing with face pulls and dumbbell rows.

Variations & Alternatives

FAQ

Incline or standing reverse fly? Incline is stricter and removes lower-back fatigue. Standing allows more weight. Use both.

How light should I go? 4-8 kg per dumbbell. The rear delts are small; quality contractions matter most.
