Setup

Adjust the seat so your elbows line up with the machine’s pivot point.
Place the top of your arms firmly on the pad or arm support so your elbows aren’t hanging in the air.
Choose a comfortable grip on the handles, palms up for the classic version.
Start with a light weight to learn the movement before adding more load.
Keep your feet flat on the floor and your back against the pad if the machine has one.

How to do it

Sit tall with your chest slightly up, shoulders relaxed, eyes forward.
Let your arms extend almost all the way down without forcefully locking your elbows.
Inhale, then bend your elbows to curl the handles up in 1–2 seconds, keeping your upper arms on the pad.
Lift until you feel a strong squeeze in your biceps, without bending your wrists.
Lower the weight slowly in 2–3 seconds, controlling it back to the start position.
Keep a steady pace and breathe: exhale on the way up, inhale on the way down.

Common mistakes

Moving shoulders or back around
Instead : Set your shoulder blades slightly back and keep your upper arms glued to the pad. Focus on only bending at the elbows, like the rest of your body is locked in place.
Swinging up and dropping down
Instead : Aim for 1–2 seconds up and 2–3 seconds down. Use a weight you can control smoothly from the first rep to the last.
Elbows drifting forward
Instead : Imagine your elbows are stuck to the pad with glue. Keep them fixed in one spot and avoid pulling with your upper arm.
Bent or broken wrists
Instead : Keep your wrists straight in line with your forearms. Grip the handle just firmly enough to control it, without crushing it.

Coach tips

To feel your biceps more, think of bringing your forearm toward your biceps instead of just pulling the handle.
If you lose control at the end of a set, drop the weight a bit and keep the same slow tempo.
Keep a slight bend at the bottom of the range, instead of fully locking your elbows, to stay comfortable.
You can pause for 1 second at the top of the curl to really squeeze your biceps before lowering the weight.

Variations

Machine reverse-grip biceps curl: same movement but with palms facing down for a different feel in the biceps.
Single-arm machine biceps curl: train one arm at a time to better focus on each side.
Machine biceps curl (two-arm): classic version with both arms at once, palms up.

Sets and reps

You’ll often see the seated biceps curl machine used for 3–4 sets of 8–15 reps, usually later in an upper body or arm workout.

Common questions

How high should I set the seat on the biceps curl machine?

Set the seat so your elbows line up with the machine’s rotation axis and the top of your arms rest fully on the pad. If your elbows sit too high or too low, adjust the seat until they match the pivot point.

Should I fully straighten my arms at the bottom?

You can go close to full extension for good range of motion, but avoid snapping your elbows straight. Keep a slight bend to stay comfortable and keep tension on your biceps.

I don’t feel my biceps much on the machine, what can I do?

Lower the weight, press your arms more firmly into the pad, and slow down the descent. Focus on bending only at the elbows and hold a one‑second squeeze at the top of each rep.

Is the machine or dumbbells better for biceps?

Both have their place. The biceps curl machine gives you a stable, guided path that makes it easier to focus on the feeling. Dumbbells ask for more control. You can use both, depending on what you like and what you want to practice.
