Machine Preacher Curls

Machine Preacher Curls is a beginner-level isolation in the strength category that primarily works the biceps. It is performed with machine.

How to do it

1. 1Sit down on the Preacher Curl Machine and select the weight.
2. 2Place the back of your upper arms (your triceps) on the preacher pad provided and grab the handles using an underhand grip (palms facing up). Tip: Make sure that when you place the arms on the pad you keep the elbows in. This will be your starting position.
3. 3Now lift the handles as you exhale and you contract the biceps. At the top of the position make sure that you hold the contraction for a second. Tip: Only the forearms should move. The upper arms should remain stationary and on the pad at all times.
4. 4Lower the handles slowly back to the starting position as you inhale.
5. 5Repeat for the recommended amount of repetitions.

Tips and common mistakes

• •Focus on the muscle contraction and control the eccentric (lowering) phase.
• •Add load only once you complete all reps with good form — progressive overload.
• •Initiate the pull from the target muscle rather than jerking with body momentum.
• •Prioritize full range of motion over heavy weight with partial reps.

Sets and reps

For hypertrophy: 3–4 sets × 8–12 reps with 1–2 reps in reserve (RPE 7–9) and 1–2 minutes rest. For strength: 3–5 × 4–6 with longer rest.
