Dumbbell Lateral Raises
Dumbbell lateral raises are an isolation exercise that lifts the arms out to the sides to build the lateral deltoid, the muscle that gives the shoulders their width.

How it is executed
- Stand upright holding dumbbells at your sides.
- With a slight bend in your elbows, raise your arms out to the sides until shoulder level.
- Pause, then lower slowly.
- Keep your torso still.
Common mistakes
- Starting each rep with a heave from the torso or knees. Momentum raises the dumbbell, not the delt. If you need to swing to finish the set, the load is too heavy.
- Raising well above shoulder height. Past that point the upper traps take over and the side delt loses tension. Stop the dumbbells at shoulder level.
- Dropping the dumbbells on the way down. The controlled lowering is where the delt accumulates most of the work in this exercise. Take two or three seconds and keep the tension.
Frequently asked questions
- Which muscles do dumbbell lateral raises work?
- The main muscle is the lateral deltoid, the middle portion of the shoulder, which is what lifts the arm out to the side. The supraspinatus helps at the start of the movement and the front deltoid joins in if the dumbbells drift forward. The upper trapezius takes over when the arms rise above shoulder height or when you shrug, which is exactly what to avoid.
- How high should you raise the arms on lateral raises?
- Until the hands reach shoulder height, with the arms almost parallel to the floor. Above that point the lateral deltoid gains no more tension and the upper trapezius takes over the movement. Keep a slight bend in the elbow and the hands neutral, without turning the pinky up: that rotation adds no work for the deltoid and puts the shoulder in an awkward position under load.
- How much weight should you use for dumbbell lateral raises?
- Much less than most people try. The lateral deltoid is a small muscle working through a long lever, so light dumbbells already create a lot of tension. The usual range is 12 to 20 reps with a load that lets you raise without swinging the torso and lower in two to three seconds. If you need to rock to finish the set, the dumbbell is too heavy.
- What is the difference between lateral raises with dumbbells, cable and machine?
- With dumbbells the tension is minimal at the bottom and maximal at the top, because the lever grows with arm height. The cable keeps the resistance even through the whole range, including the bottom position where dumbbells barely load. The machine fixes the path and lets you focus only on pushing against the pads. All three are valid and many plans rotate them across weeks.
