Here you are given a plan for making a Preacher curl, which can also be found under the name Preacher bench.

Whether you are a fitness expert or someone who just enjoys keeping in shape, doing preacher curls not only activates and strengthens a large number of your arm muscles, but also contributes to your health in general. The preacher curl exercise targets the brachialis muscle located in the upper arm (aids the flexion of your elbow).

  4. Inhale as you lower the dumbbell. Exhale as you curl the dumbbell to the starting position.

Repeat for the recommended amount of repetitions.
