Should I use a full range of motion or stop at parallel on the lateral raise machine?

Stop when your elbows reach shoulder height or slightly below parallel to maximize deltoid tension. Going higher shifts the load to the traps and reduces the effectiveness for side delt development.

Is the lateral raise machine better than dumbbell lateral raises?

The machine provides a more consistent resistance curve and requires less stabilization, making it easier to isolate the deltoids with heavier loads. Dumbbells offer more freedom of movement and engage stabilizer muscles, so both have value depending on your goals.

How do I prevent my traps from taking over on the lateral raise machine?

Focus on keeping your shoulders down and depressed throughout the movement rather than shrugging upward. Think about pushing the pads outward with your elbows rather than lifting with your upper body.

Lateral Raise (Machine)

The lateral raise machine is a fixed-path exercise that isolates the deltoids by raising padded arms outward to shoulder height. It suits lifters who want consistent tension on the side delts with less stabilization demand than free weights.

Muscle group: Shoulders
Primary muscles: deltoids
Equipment: Machine

How to do the Lateral Raise (Machine)

Adjust the seat height so your shoulders align with the machine's pivot point and sit with your back against the pad.
Place your forearms or upper arms against the padded levers, depending on machine design, and grasp the handles lightly.
Raise the padded arms outward and upward in a smooth arc until your elbows reach shoulder height.
Pause briefly at the top, then lower the arms under control back to the starting position without letting the weight stack touch.

Form tips

Lead the movement with your elbows rather than your hands to keep tension on the deltoids throughout the range of motion.
Stop at shoulder height rather than raising higher to avoid shifting tension to the traps and reducing deltoid engagement.
Keep a slight bend in your elbows and maintain that angle throughout the movement rather than straightening or bending your arms.

Common mistakes

Leaning back or using momentum to lift the weight reduces deltoid isolation and can strain the lower back.
Shrugging the shoulders upward shifts tension from the side delts to the upper traps and reduces the exercise effectiveness.
Raising the arms too high past shoulder level decreases deltoid tension and increases unnecessary stress on the shoulder joint.

Sets and reps

For hypertrophy, perform 3 to 4 sets of 10 to 15 reps with moderate weight and controlled tempo; for strength, use 3 to 5 sets of 6 to 8 reps with heavier resistance.
