Incline Curl

A dumbbell curl done sitting back on an incline bench: your arms hang behind your torso, so each rep starts with your biceps stretched before you curl the weights up.

Incline Curl (Dumbbell)

Loads from YouTube only when you press play. The video is by an independent creator.

Why do it

Incline curls suit anyone who wants more from the bottom of the curl, where standing curls go light. Leaning back puts your upper arms behind your body, so the biceps starts each rep in a long, stretched position and you can't swing. You'll use less weight than on standing curls, and a more reclined bench gives you more stretch. Compared with a spider curl, which focuses on the squeeze at the top, this one is all about the bottom.

How to do it

  1. Set a bench to 45-60 degrees, sit back against it and let your arms hang straight down, palms facing forward.

  2. Curl the dumbbells up without moving your upper arms.

  3. Lower them all the way until your arms are straight again.

  4. The incline puts your biceps on stretch at the bottom, which is the point of the variation. Don't cut the bottom of the rep short.

Common mistakes

Rolling your shoulders off the bench

As the weight gets hard, your shoulders roll forward and the stretch disappears. Keep your back and shoulders against the pad for the whole set.

Swinging the upper arms forward

Bringing your elbows forward to finish the curl takes the biceps out of the stretched position. Keep your upper arms hanging straight down and move only your forearms.

Cutting the bottom short

The stretch at the bottom is the reason to do this curl. Lower all the way until your arms are straight.

Setting the bench too upright

Close to vertical, the bench just gives you a seated curl. Recline it enough that your arms hang behind your torso.

Sets, reps and progression
