Dumbbell Incline One Arm Hammer Press form demonstration - targeted for Triceps Upper Arms workouts

Dumbbell Incline One Arm Hammer Press

Pressing one arm at a time with a neutral grip from an incline bench isolates the upper chest and triceps on each side individually, exposing any strength gap between them. The hammer grip keeps the shoulder in a safer position through the press than a standard grip would at this angle. It's a useful accessory for evening out asymmetries that a two-arm press tends to mask.

  • Elbow migration: Keep the upper arm stationary to prevent the movement from turning into a different exercise.
  • Inconsistent elbow tracking: Follow the intended path for your elbows to ensure they do not excessively flare outward.
