Forearm exercises

What actually builds forearms?

Grip. Your forearm fires on every deadlift, every row and every hang from the pull-up bar, and it is usually those sets, not wrist curls, that decide how it looks. The exercises on this list add to that work, they do not replace it.

Training forearms on their own is worth it in two cases: when your grip gives out before your back does on a pull, and when you care about how the forearm looks. In the first case, farmer's walks will do more than curls on a bench - carrying a load for the whole distance taxes the grip in a completely different way than a set of wrist reps.

Worth remembering that the farmer's walk is a whole-torso exercise: the instructions say it plainly, tall posture and shoulders pulled back. If your back rounds, it stops being a grip exercise and turns into an endurance test for your lower back.

Flexors or extensors?

The inside of the forearm, the flexors, works every time you hold anything, which is why it is usually much stronger. The back of the forearm gets almost nothing in normal training, because wrist extension does not show up in any big movement. That is why the list carries both versions, the curl and the extension, with a barbell and with dumbbells.

The practical consequence is that the weight from one side does not carry over to the other. Dumbbells you curl comfortably can be too heavy by half once you turn your hands over. That is not a mistake in picking the load, it is the normal strength difference between the two groups.

If your wrist does not like a straight bar, the catalog has an EZ bar version and a cable version. Both let you set your hand at a different angle in the same movement, and the cable also keeps the resistance on at the point where a barbell starts to unload itself.
