The verdict

Reverse Flyes has 6-step instructions, among the most thoroughly documented of the 127 shoulders exercises PlainExercise catalogues.

How PlainExercise computes exercise placement

Shoulders

Reverse Flyes is a beginner isolation movement that trains the Shoulders. It requires a dumbbell. There are 0 known variations and 8 peer exercises that target the same primary muscle.

  • 1 of 9 exercises targeting the Shoulders
  • Level: beginner

PlainExercise cross-links 0 variations and 8 peer exercises sharing the same primary muscle.

What the Reverse Flyes Data Reveals · DEEP · PULL/ISOLATION

Reverse Flyes opens on mechanic class: ISOLATION pull work for shoulders with 0 catalogued assistants, joint involvement separates this page from isolation peers.

Among 873 exercises, 6 steps sit in the upper third (≥ 5). Longer step lists usually mean finer setup cues, not a harder movement by themselves.

Reverse Flyes is classified as a beginner-level isolation movement with a pull force profile, primarily training the Shoulders. The canonical form requires a dumbbell in the strength category. Within the shoulders cohort, 9 catalogued movements share the primary target; no alternate-equipment variations are catalogued yet.

Context matters: taxonomy (level, mechanic, force, musculature, equipment) does not account for individual biomechanics, joint history, or recovery. Common-mistake framing below is derived from classification fields, not case-specific coaching. Not medical or personal-training advice. Consult a physician or certified trainer before starting, especially with injuries, cardiovascular conditions, recent surgery, or pregnancy.

Reverse Flyes catalog footprint

Among 127 exercises whose primary muscle is shoulders, Reverse Flyes ranks #43 by catalogued variation count (0 listed heres). The upstream file attaches 2 images to this slug. See the step-count ranking for shoulders for peer documentation depth.

Muscles worked

According to the Free Exercise DB classification, Reverse Flyes trains the shoulders as the prime mover and no catalogued secondary muscles. The source classifies muscles as primary or secondary, it does not measure activation, so we show involvement, not percentages.

Intensity context

For reference, here is where common activities sit on the MET intensity scale. Reverse Flyes does not have a measured MET in the source data, its intensity depends on the load and effort you use. Estimate calories for any activity with the calorie calculator.

MET Intensity Zones, Exercise Intensity Chart Horizontal bar chart showing how six common exercises map to four MET intensity zones: Light (1-3 MET), Moderate (3-6 MET), Vigorous (6-9 MET), and Very Vigorous (9+ MET). Walking at 3.5 MET falls in Moderate; Jump Rope at 12.3 MET reaches Very Vigorous.

MET values from the Compendium of Physical Activities (Ainsworth et al., 2011). A general reference scale, not a rating of this specific movement.

How to do it

  1. To begin, lie down on an incline bench with the chest and stomach pressing against the incline. Have the dumbbells in each hand with the palms facing each other (neutral grip).
  2. Extend the arms in front of you so that they are perpendicular to the angle of the bench. The legs should be stationary while applying pressure with the ball of your toes. This is the starting position.
  3. Maintaining the slight bend of the elbows, move the weights out and away from each other (to the side) in an arc motion while exhaling. Tip: Try to squeeze your shoulder blades together to get the best results from this exercise.
  4. The arms should be elevated until they are parallel to the floor.
  5. Feel the contraction and slowly lower the weights back down to the starting position while inhaling.
  6. Repeat for the recommended amount of repetitions.

Reverse Flyes Documentation Depth

Reverse Flyes carries 6-step instructions (840 characters of Free Exercise DB text) - enough upstream detail to compare documentation depth inside the shoulders cohort, not just the taxonomy badges above. Across 127 catalogued shoulders movements, the average instruction record is 623 characters and 4.2 steps; 82 of those (64.6%) clear the same ≥500-character rich bar used here. This page ranks #21 of 127 by instruction-character length (1.35× the cohort average).

Among the 123 exercises that also use a dumbbell, average instruction length is 790 characters; 50 of those peers are longer than this record. Equipment-matched peers are the honest comparison when you are choosing a substitute implement for the same pattern.

Other well-documented shoulders movements (same ≥500-character bar):

Common mistakes

  • Rushing through reps before the pattern is grooved - at this stage, a slow, controlled tempo (2-3s down, 1-2s up) on Reverse Flyes teaches the nervous system the movement far faster than speed does.
  • Cutting the range of motion short - moving the shoulders through its full safe range on Reverse Flyes is what most reliably separates effective reps from wasted ones.
  • Using momentum instead of muscle, isolation movements like Reverse Flyes reward strict form. If you're swinging the weight, it's too heavy.
  • Shrugging the shoulders up toward the ears on pull movements, keep shoulder blades down and back to load the correct muscles.
  • Breathing out of sync with the lift on Reverse Flyes - brace and inhale during the lowering phase, exhale on the exertion, especially important with a dumbbell where control matters most.

Who this is for

  • People new to resistance training who want to build a foundation in the movement pattern
  • People who want to train the Shoulders
  • People who have access to a dumbbell

Who this is NOT for

  • People hunting equipment swaps, PlainExercise lists 0 catalogued variations for Reverse Flyes; browse 8 peer shoulders exercises for alternate patterns instead.
  • Anyone with acute pain in the joints or muscles involved, pain is a stop signal, not a soreness signal
  • People with unresolved injuries in the loaded joints, seek clearance from a physical therapist first
  • Anyone with a recent surgery, cardiovascular limitation, or pregnancy complication without physician clearance

Progression path

Once Reverse Flyes feels comfortable with your current load, progress by (a) adding reps until you can complete 12+ per set, (b) increasing resistance by 2.5-5%, (c) moving to harder variations such as single-limb or longer lever versions, and eventually (d) stepping up to intermediate-level movements that train the same muscle.

Safety notes · DUMBBELL · PULL/ISOLATION · FLOOR

  • On PULL/ISOLATION shoulders work, warm up 5–10 minutes before loading Reverse Flyes; keep first sets light until the path feels automatic.
  • Sharp or joint pain is a stop signal. Muscle soreness during sets is normal; pain is not.
  • Beginners on DUMBBELL gear: cut volume before cutting form, drop a set rather than rush reps.

Using the reverse flyes

A beginner isolation movement for the shoulders - here's how to put it to work.

  • Train the shoulders 2–3 times a week with 48+ hours between hard sets; pair this with other shoulders movements for balanced development. All shoulders exercises
  • Match the load and rep range to your goal, strength, size, or endurance each call for a different scheme. Strength vs hypertrophy
  • As an isolation movement, use it to target the shoulders directly after your compound lifts. Compound vs isolation

Form before load. If a movement causes sharp or joint pain, stop and substitute a safer alternative, this is general information, not medical or training advice.
