Dumbbell French Press

The Dumbbell French Press is an isolation exercise performed lying on a bench that targets the triceps muscles by extending the elbows against resistance. It effectively builds arm size and strength while allowing for independent limb movement to correct muscle imbalances.

How Iridium Programs This

Since the overhead position specifically isolates the triceps long head, Iridium uses sub-muscle-group fatigue tracking to ensure this specific area is recovered enough for direct work. The system analyzes your 7-day training history to balance this accessory lift against heavier compound pressing volume to prevent overtraining. Using your RPE feedback, Iridium adjusts the load and rep targets to drive hypertrophy while keeping you within your Maximum Recoverable Volume.

Form Cues

Do
  • Keep your upper arms stationary and vertical
