Dumbbell Alternate Preacher Curl: How to Do It & Muscles Worked
The dumbbell alternate preacher curl is an isolation exercise targeting the biceps, performed on a preacher bench to minimize cheating and maximize biceps engagement. It is performed by alternating arms, curling a dumbbell up while keeping the upper arm stationary on the pad.
How to do the dumbbell alternate preacher curl
- Step 1: Sit on a preacher bench with a dumbbell in each hand, palms facing up.
- Step 2: Rest your upper arms on the pad of the preacher bench, allowing your arms to fully extend.
- Step 3: Keeping your upper arms stationary, exhale and curl the dumbbell in your right hand as you contract your biceps.
- Step 4: Continue to curl the dumbbell until your biceps are fully contracted and the dumbbell is at shoulder level.
- Step 5: Pause for a moment, then inhale and slowly lower the dumbbell back to the starting position.
- Step 6: Repeat the movement with your left arm.
- Step 7: Continue alternating arms for the desired number of repetitions.
Sets, reps and programming
| 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.
