How to do the dumbbell lying extension (across face)

  1. Step 1: Lie flat on a bench with your feet flat on the ground and your head at the end of the bench.
  2. Step 2: Hold a dumbbell with both hands and extend your arms straight up above your chest, palms facing each other.
  3. Step 3: Keeping your upper arms stationary, slowly lower the dumbbell in an arc behind your head until your forearms are parallel to the ground.
  4. Step 4: Pause for a moment, then contract your triceps to bring the dumbbell back to the starting position.
  5. Step 5: Repeat for the desired number of repetitions.

Sets, reps and programming

Suggested sets, reps and rest for the dumbbell lying extension (across face) by training goal
Goal Sets Reps Rest Effort
Strength 3–5 3–6 3–5 min 1–3 reps in reserve
Muscle growth 3–4 6–12 2–3 min 1–2 reps in reserve
Muscular endurance 2–3 12–20 1–2 min 1–3 reps in reserve

Ranges follow the ACSM position stand on progression in resistance training. Muscle grows across a wide range of loads when sets end close to failure (Schoenfeld et al., 2017), longer rests between heavy sets support strength and size (Schoenfeld et al., 2016), and stopping a rep or two short of failure works about as well as training to failure (Grgic et al., 2022). Estimate your working weights with the strength calculators.
