Published: May 29, 2025 · Updated: Mar 15, 2026

The Bent Arm Lateral Raise is a standing isolation exercise that targets the side deltoids using a fixed bend in the elbows. Shortening the lever this way reduces joint strain and allows more control compared to straight-arm variations. Lateral raise variations are among the most effective movements for isolating the lateral deltoid, with dumbbell versions producing strong, consistent activation throughout the range (Larsen et al., 2025).

The side delts perform the majority of the work, while the upper traps and surrounding shoulder muscles assist in guiding and stabilizing the lift. EMG analysis of lateral raise movements confirms significant middle deltoid engagement during abduction-based shoulder exercises (Ferreira et al., 2003a). Because the elbows remain bent, tension stays more consistent through the entire raise, shifting focus away from momentum toward deliberate shoulder engagement.

This movement works well in hypertrophy-focused shoulder sessions and higher-rep accessory blocks. Validated EMG research on conditioning exercises supports the lateral raise as a reliable shoulder-builder across training levels (Ferreira et al., 2003b). It is a practical option for lifters who struggle with control on standard lateral raises or who want steady tension with lighter loads.

Technique and form

How to perform the Bent Arm Lateral Raise

Stand with your feet shoulder-width apart, knees slightly bent, and hold a dumbbell in each hand with palms facing inward at your sides.
Bend your elbows to approximately 90 degrees and maintain this fixed angle throughout the entire movement.
Brace your core and maintain a neutral spine position while slightly tilting your chest forward from the hips.
Exhale as you raise both arms out to the sides, keeping the bent-arm position until your elbows reach shoulder height.
At the top position, your upper arms should be parallel to the floor while maintaining the 90-degree bend in your elbows.
Pause briefly at the top of the movement, focusing on squeezing your shoulder blades together.
Inhale as you slowly lower the weights back to the starting position with controlled movement, maintaining tension in your shoulders.
Keep your wrists neutral and aligned with your forearms throughout the entire exercise to prevent strain.

Important information

Make sure your elbows stay at the same angle throughout the movement – avoid straightening your arms during the lift.
Keep your shoulders down and away from your ears to properly engage the middle deltoids rather than the upper traps.
If you feel neck strain, reduce the weight and focus on proper form before increasing resistance.
Control the descent rather than letting gravity do the work – this increases time under tension for better muscle development.

Common Mistakes: Bent Arm Lateral Raise

Rounding your upper back

Keep your chest up and shoulders pulled back. A rounded back shifts the load away from the target muscles and strains your spine.

Using your arms too much instead of your back

Focus on pulling with your elbows, not your hands. Think about squeezing your shoulder blades together.

Moving too fast

Slow reps build more muscle during isolation exercises. Aim for 2 seconds up, 2 seconds down.

Rushing through reps

Slow, controlled reps work the muscle much better than fast, sloppy ones. Take your time on both the lifting and lowering phase.

Holding your breath

Breathe out during the hard part of the movement and breathe in as you return to the start. Holding your breath can spike your blood pressure.

Benefits of the Bent Arm Lateral Raise

Builds stronger side shoulder muscles

The Bent Arm Lateral Raise directly targets your side shoulder muscles, helping you build strength and size in this area over time.

Focused muscle targeting

As an isolation exercise, the Bent Arm Lateral Raise lets you zero in on your side shoulder muscles without other muscles taking over. This is great for bringing up a weak point or adding definition.

Increases overall strength

Regularly performing the Bent Arm Lateral Raise with progressive weight builds functional strength that carries over to other exercises and daily life.

Equipment advantage

Dumbbells allow each side to work independently, helping fix strength imbalances, giving you a training benefit that's hard to replicate with other setups.

Train anywhere

The Bent Arm Lateral Raise can be done at home with minimal or no equipment, making it easy to stay consistent even when you can't get to the gym.

Muscles Worked: Bent Arm Lateral Raise

FAQ - Bent Arm Lateral Raise

What muscles does the Bent Arm Lateral Raise target?

The Bent Arm Lateral Raise primarily targets the lateral deltoids (side shoulders), with secondary activation in the front deltoids and upper trapezius. The bent arm position allows for greater focus on the medial deltoid heads while reducing strain on the rotator cuff.

How does the Bent Arm Lateral Raise differ from standard lateral raises?

The bent arm position creates a mechanical advantage that often allows for heavier weight compared to straight-arm variations. This modification can reduce strain on the shoulder joint while maintaining tension on the lateral deltoids, making it particularly beneficial for those with shoulder discomfort during traditional raises.

What are common form mistakes to avoid with this exercise?

Avoid arching your lower back or lifting your buttocks off the seat when pressing heavier weights. Keep your core braced, maintain contact with the backrest throughout the movement, and don't lock out your elbows at the top position to maintain tension on the deltoids.

How heavy should I go with Bent Arm Lateral Raises?

Choose a weight that allows you to perform 10-15 controlled repetitions with proper form. You should feel your lateral deltoids working, but not so heavy that you compensate with body momentum or lose the mind-muscle connection. Most lifters will use lighter weights than they do for pressing movements.

How can I incorporate Bent Arm Lateral Raises into my training routine?

Perform this exercise 1-2 times weekly, either as a primary shoulder builder on dedicated deltoid days or as a finishing movement after compound exercises like overhead presses. For hypertrophy, aim for 3-4 sets of 10-15 reps with controlled tempos, focusing on the contraction at the top of each repetition.

Workouts with Bent Arm Lateral Raise

Best Side Delt workouts

The side delts, or lateral deltoids, are responsible for the width and rounded shape of your shoulders. Well-developed side delts enhance upper body aesthetics and play a functional role in shoulder abduction and stabilization. These workouts focus on isolating the lateral delts using exercises like lateral raises, upright rows, and overhead presses. Whether you're training for appearance or performance, strong side delts contribute to balanced, injury-resistant shoulders.
