Power Sled Rear Fly
Power Sled Rear Fly Exercise Description
The Power Sled Rear Fly is a standing reverse-fly variation using sled straps or handles to create horizontal resistance. It trains horizontal abduction and scapular retraction, emphasizing the posterior deltoids, middle trapezius, and rhomboids, with assistance from the lower trapezius and rotator cuff for shoulder stability. Because the sled provides smooth, continuous tension, the movement rewards controlled mechanics over momentum. The goal is to open the arms in a wide arc while keeping the torso steady and the shoulders down and back. Expect isometric contribution from the forearm flexors and trunk stabilizers as you maintain a neutral spine and steady base.

How To Do The Power Sled Rear Fly Exercise
‘- Attach two handles/straps to the sled anchor in front of you. Step back to create light tension.
– Stand tall in an athletic stance (feet hip-width, soft knees). Brace lightly; ribs stacked over pelvis; neck long.
– Grip with a neutral or slight “thumbs-up” orientation. Wrists straight; elbows softly bent.
– Start with hands together at about chest/shoulder height in front of you, shoulders set down and back.
– Initiate by drawing the shoulder blades together and slightly down.
– Sweep the arms out to the sides in a wide arc until hands are roughly in line with the shoulders. Keep elbows slightly bent throughout.
– Pause briefly while maintaining scapular retraction without shrugging.
– Return along the same path with control, allowing the shoulder blades to protract without losing trunk position.
– Keep movement at the shoulders; avoid twisting, leaning, or arching the lower back.
– If you feel upper‑trap takeover, lower the hand path a few centimeters below shoulder height and reaffirm shoulder depression.
Power Sled Rear Fly Tips
‘- Step back just enough to create light tension on the straps before you start.
– Stand tall with feet about hip-width, knees soft, and ribs stacked over your pelvis.
– Keep your neck long and avoid jutting the head forward as you pull.
– Use a neutral or slight “thumbs-up” grip with straight wrists and softly bent elbows.
– Begin with hands together at chest/shoulder height and shoulders set down and back.
– Initiate each rep by drawing your shoulder blades together and slightly down before moving the arms.
– Sweep your arms out in a wide arc until your hands are roughly in line with your shoulders, keeping the same slight elbow bend.
– Pause briefly in the open position, maintaining scapular retraction without shrugging.
– Return along the same path with control, allowing your shoulder blades to protract without losing trunk alignment.
– Keep the motion at the shoulders only; avoid twisting, leaning, or arching your lower back.
– If you feel your upper traps taking over, lower your hand path a few centimeters below shoulder height and focus on keeping the shoulders depressed.
Power Sled Rear Fly Beginner Introduction
The Power Sled Rear Fly is a standing reverse-fly style movement performed with sled straps or handles that pull forward instead of downward. As the sled slides, it supplies steady sideways resistance, turning each repetition into a smooth, deliberate pull rather than a momentum-based swing. The arms travel out in a broad arc at roughly chest level, so the action highlights the rear shoulders, upper back, and traps, with help from the rotator cuff for shoulder control.
Because the sled is out in front, the body works as a united system. The shoulders and upper back create the motion while the core and lower body act as a solid frame so the trunk does not sway or twist. The wrists and forearms contribute by holding the handles in place throughout the pull. This combination of wide arm movement, steady posture, and continuous tension builds awareness of shoulder position and encourages precise, controlled reverse-fly mechanics.
