Hammer Curl to Lateral Raise

The hammer curl to lateral raise is a dumbbell combination exercise that performs a neutral-grip biceps curl immediately followed by a lateral raise within the same repetition. The hammer curl emphasizes the biceps brachii and brachialis while the lateral raise isolates the middle deltoid, so combining them trains both muscle groups with a single set of dumbbells. It is commonly used to save time in arm-and-shoulder workouts and adds a coordination challenge beyond either exercise performed on its own.

Muscles Targeted

• Primary: Biceps brachii, brachialis, lateral deltoid
• Secondary: Anterior deltoid, forearm flexors
• Tertiary: Trapezius, core stabilizers

Starting Position

Stand with feet shoulder-width apart, holding a dumbbell in each hand at your sides with palms facing your body (neutral grip). Keep your shoulders back, chest up, and core braced.

Execution Steps

1. Curl the dumbbells upward by bending your elbows, keeping them tucked close to your torso, palms facing each other throughout
2. Squeeze at the top of the curl when the dumbbells reach shoulder height, pausing briefly to contract the biceps
3. Lower the dumbbells back down to your sides in a controlled manner until your arms are fully extended
4. Raise both dumbbells out to the sides with a slight bend in the elbows, lifting until your arms are roughly parallel to the floor
5. Pause briefly at shoulder height, leading with the elbows rather than the hands
6. Lower the dumbbells back down to your sides with control, completing one full repetition

Form Cues

• Keep elbows pinned to your torso during the curl portion to isolate the biceps and brachialis
• Lead with your elbows, not your hands, during the lateral raise to keep tension on the deltoids
• Avoid using momentum or torso swing on either half of the movement
• Stop the lateral raise at shoulder height: going higher shifts load to the trapezius
• Keep wrists neutral throughout both phases

Common Mistakes

• Swinging the torso to generate momentum: This reduces muscle tension and increases lower back strain; keep the core braced and the movement strict.
• Flaring elbows out during the curl: This shifts stress away from the biceps; keep elbows close to your sides.
• Raising the dumbbells above shoulder height on the lateral raise: This recruits the traps instead of the deltoids and stresses the shoulder joint; stop at parallel.
• Using weight that is too heavy: Excess load causes cheating on both movements and reduces isolation; choose a weight that allows full control.
• Rushing the transition between curl and raise: This causes loss of control and reduces time under tension; pause briefly between phases.

Variations

• Alternating hammer curl to lateral raise: Perform one arm at a time to increase focus and stability demand
• Seated hammer curl to lateral raise: Removes lower body momentum for stricter upper body isolation
• Cable hammer curl to lateral raise: Cables provide constant tension throughout the range of motion
• Hammer curl and lateral raise as separate exercises: Split into two distinct movements to allow heavier loading on each

Tips for Progression

• Increase weight in small increments (2.5-5 pounds) once 12-15 reps are achieved with strict form
• Add a brief isometric pause at the top of each phase to increase time under tension
• Progress to single-arm variations to address strength imbalances between sides
• Increase total sets or reps before adding load if form begins to break down

Training Notes

Include the hammer curl to lateral raise in arm or shoulder-focused sessions 1-2 times per week, typically for 3 sets of 10-12 reps with 45-60 seconds of rest between sets. It works well as a finishing exercise after heavier compound pressing and pulling movements, since it uses lighter loads and relies on strict form rather than maximal weight.
