How to do the preacher curl with machine

  1. A Preacher Curl uses a special bench to support the triceps and isolate the biceps to build the arms. This version of the exercises is a machine exercise. This is a good exercise for beginners.
  2. Adjust the seat of the bench so your arms are level with the top of the bench. Rest your arms against the bench and extend them fully. Grasp the bar underhand (palms facing up) and pull it towards your head. Pause for a moment and then lower the bar back to starting position.
  3. Note: Perform this exercise in a slow controlled manner for best results. Read the instructions on the machine before performing this exercise.

Muscles worked

The prime mover is the biceps brachii, which bends the elbow and rotates the forearm palm-up.

Even with a single joint doing the moving, the muscle is not working alone — the forearms hold the grip, which is often what gives out first.

How this movement works

Everything happens at one joint. That gives you direct control over where the tension sits; the trade-off is that the muscle gets no help, so the load that feels hard here is a fraction of what a multi-joint version of the pattern would take. Slow, complete repetitions beat heavy ones.

It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.

What you need

The machine fixes the path, removing the balance demand and letting you train close to failure without a spotter. The cost is the stabilising work a free weight would have made you do.
