Resistance Band Pullapart (Pronated at 90 Degrees)
Strengthen your rear deltoids and improve shoulder posture with resistance band pullaparts. Keep arms bent at 90 degrees and pronated grip.
Description
This exercise involves pulling a resistance band apart while keeping your arms raised and bent at a 90 degree angle.
How to Do Resistance Band Pullapart (Pronated at 90 Degrees)
- 1Setup
Stand tall with a neutral spine and hold a resistance band with a pronated grip (palms facing down), hands shoulder-width apart.
- 2Setup
Raise your arms directly in front of you to shoulder height, bending your elbows to a strict 90-degree angle so your forearms are parallel to the floor.
- 3
Initiate the movement by squeezing your shoulder blades together, pulling the band outwards while maintaining the 90-degree bend in your elbows.
- 4
Continue pulling until your upper arms are approximately in line with your torso, feeling a strong contraction in your rear deltoids.
- 5
Slowly and with control, reverse the movement to return to the starting position, resisting the band's pull throughout the eccentric phase.
Tips
- Focus on initiating the pull by retracting your shoulder blades, rather than just pulling with your arms, to maximize rear deltoid activation.
- Maintain constant tension on the band throughout the entire range of motion, never allowing it to go completely slack.
- Keep your wrists straight and aligned with your forearms to prevent undue stress or discomfort in the wrist joint.
- Control the eccentric (return) phase of the movement for 2-3 seconds to enhance muscle growth and control.
Common Mistakes
- ×Rounding the shoulders forward during the pull disengages the target muscles; fix this by actively pulling your shoulder blades back and down.
- ×Extending the elbows during the outward pull shifts the tension away from the rear deltoids; fix this by maintaining a strict 90-degree elbow bend throughout.
- ×Using momentum to yank the band apart reduces muscle activation; fix this by performing the movement slowly and deliberately, focusing on muscle contraction.
