The dumbbell seated alternate front raise is a shoulder isolation exercise that primarily targets the front of the shoulder (anterior deltoid), with help from the side deltoid, upper chest (clavicular head of the pectoralis major), and the serratus anterior. Raising one dumbbell at a time from a seated position removes leg drive and torso sway, making it a strict, controlled way to build anterior deltoid strength and shape.
How to do the Dumbbell Seated Alternate Front Raise
- 1Sit upright on a bench with your feet flat on the floor and a dumbbell in each hand, resting against the front of your thighs with palms facing your legs.
- 2Brace your core, set your shoulder blades down, and keep your chest tall against the back support or in a neutral upright posture.
- 3Raise one dumbbell straight out in front of you with a slight bend in the elbow, leading with the wrist until the dumbbell reaches about shoulder height.
- 4Pause briefly at the top, keeping the arm roughly parallel to the floor without shrugging the shoulder up toward your ear.
- 5Lower the dumbbell under control back to the front of your thigh.
- 6Repeat the movement with the opposite arm, alternating sides for the full set.
- 7Once you complete your reps on both arms, lower the dumbbells fully and set them down with control.
Form tips
- Keep a fixed, slight bend in your elbow throughout the rep so you isolate the anterior deltoid instead of turning it into a straight-arm swing.
- Move at a steady tempo and pause briefly at shoulder height to maximize tension on the front delt.
- Keep your non-working arm relaxed at your side so it doesn't help heave the weight up.
- Use a lighter load than you would for pressing movements; front raises are an isolation exercise and reward control over heavy weight.
Common mistakes
- Swinging the torso or using momentum to fling the dumbbell up, which shifts work away from the anterior deltoid and strains the lower back.
- Raising the dumbbell well above shoulder height, which hands the load over to the traps and adds shoulder-joint stress with little extra delt benefit.
- Shrugging the shoulder up toward the ear during the lift, which recruits the traps instead of keeping tension on the front delt.
- Locking the elbow dead straight, which stresses the elbow and turns the lift into a long lever that the shoulder can't control.
- Rushing the lowering phase and letting the dumbbell drop, throwing away the eccentric portion of the rep.
Frequently asked questions
What muscles does the dumbbell seated alternate front raise work?
It primarily works the front of the shoulder (anterior deltoid), with the side deltoid, upper chest (clavicular head of the pectoralis major), and serratus anterior assisting as synergists.
Why do it seated and alternating instead of standing?
Sitting removes leg drive and torso sway so you can't cheat the weight up, and alternating arms lets you focus on one anterior deltoid at a time for stricter, more controlled reps.
How high should I raise the dumbbell?
Raise it to about shoulder height, so the arm is roughly parallel to the floor. Going higher shifts the work to your traps and adds shoulder-joint stress without much extra benefit for the front delt.
How many sets and reps should I do?
As an isolation move, 3 to 4 sets of 10 to 15 reps per arm with a moderate weight works well. Prioritize control and full range over chasing heavy dumbbells.
Is the seated alternate front raise good for beginners?
Yes. The seated position and one-arm-at-a-time rhythm make it easy to learn strict form, and starting light helps you feel the anterior deltoid working before adding load.
