Single Arm Overhead Dumbbell Lunge
The Single Arm Overhead Dumbbell Lunge is a functional compound exercise that combines a lower-body lunge with a unilateral overhead hold. This movement builds leg strength while challenging shoulder stability, thoracic mobility, and core control.
Iridium counts volume from this movement toward both your quadriceps and anterior deltoid limits, preventing overload if either muscle group is already fatigued from the last 7 days of training. Since the lift demands high stability, the AI also references your sleep data and systemic recovery score, avoiding this exercise when your readiness is low.
Form Cues
- Lock your overhead arm fully with your bicep close to your ear
- Brace your core tightly to resist leaning sideways
- Step forward and lower your hips until your back knee hovers off the floor
- Drive through your front heel to return to the starting position
- Keep your chest up and hips square to the front
- Don't let your overhead elbow bend
- Don't allow your front knee to collapse inward
- Don't arch your lower back to compensate for shoulder tightness
- Don't let the dumbbell drift away from your midline
- Don't slam your back knee into the ground
Common Mistakes
- Hyperextending the lower back
- Bending the overhead arm
- Taking steps that are too short
- Leaning the torso forward
- Knee valgus (caving in)
Muscles Worked
This exercise primarily targets the quadriceps and glutes through the lunging pattern, building unilateral lower body strength. Simultaneously, the anterior deltoid and rotator cuff work isometrically to stabilize the load overhead, forcing the obliques and deep core muscles to engage intensely to maintain an upright posture.
