How to do the wide style dumbbell lying one arm press

  1. Step 1: Lie flat on a bench with your back supported and feet flat on the ground.
  2. Step 2: Hold a dumbbell in one hand with your palm facing towards your feet.
  3. Step 3: Extend your arm straight up towards the ceiling, keeping your elbow slightly bent. Maintain wide form throughout.
  4. Step 4: Slowly lower the dumbbell down towards your chest, keeping your elbow close to your body.
  5. Step 5: Pause for a moment at the bottom, then push the dumbbell back up to the starting position.
  6. Step 6: Repeat for the desired number of repetitions, then switch to the other arm.

Sets, reps and programming

Suggested sets, reps and rest for the wide style dumbbell lying one arm press 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.
