Incline Hammer Curl

A hammer curl done sitting back on an incline bench: your arms hang behind you with palms facing in, so you curl from a stretch while also working the brachialis and forearms.

Incline Hammer Curl (Dumbbell)

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

Why do it

It combines two things: the incline puts your biceps in a stretched starting position, and the neutral grip brings in the brachialis and forearm muscles. That makes it a useful single choice when you want both in a short arm session. Compared with the regular incline curl, you'll usually handle a bit more weight and feel it more in the forearms; compared with a standing hammer curl, you can't swing and the bottom of the rep is harder.

How to do it

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

  2. Curl the dumbbells toward your shoulders without moving your upper arms, keeping your palms facing in the whole way.

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

  4. The incline stretches the biceps at the bottom and the neutral grip loads the brachialis, so this hits both the biceps and the muscle underneath it.

Common mistakes

Letting the palms turn up

Rotating your wrists mid-rep turns it into a regular incline curl. Keep your thumbs pointing up from bottom to top.

Sliding the elbows forward

As you tire, your elbows drift forward and the stretch goes. Keep your upper arms hanging straight down from your shoulders.

Sitting up off the bench

Peeling your head and shoulders off the pad changes the angle back to a normal hammer curl. Keep your back against the bench throughout.
