Comments and tips

  • Adjust the seat to ensure that your upper arms, from armpits to elbows, lie flat on the padded surface of the preacher bench.
  • Keep your elbows in line with your shoulders.
  • Keep your body still. Only your forearms should move.
  • When you perform the barbell preacher curl, the short (inner) head of your biceps brachii enters into active insufficiency (i.e. develops slack) at the top of the curl, Therefore, the long (outer) head of your biceps brachii is activated more than is the short head.
  • Using an EZ bar might be easier on your wrists.
  • See also the cable preacher curl and the dumbbell preacher curl.
