Lever Preacher Curl
Lever preacher curls are a type of bicep exercise that involve using a lever machine to isolate and target the biceps muscles. The exercise is performed while seated on a preacher bench, which has a padded surface that supports the arms and isolates the biceps.
Lever preacher curls are an excellent exercise for building bicep strength and size, as they isolate the biceps and provide a focused contraction. They can be performed with different resistance levels, making them suitable for individuals at various fitness levels, and can be a valuable addition to any arm workout routine.

Lever Preacher Curl – Benefits
Lever preacher curls are an effective exercise for building the brachialis muscle, a key muscle located in the upper arm. While the biceps brachii muscle is often the primary focus of arm exercises, the brachialis plays an important role in elbow flexion and can add significant size and definition to the arm.
- Targeted muscle activation: The preacher bench and lever arm allow for maximum activation of the biceps muscles, which can lead to significant growth and definition over time.
- Reduced risk of injury: Because the preacher bench stabilizes the upper arm, there is less strain on the elbow and shoulder joints, reducing the risk of injury compared to other bicep curl variations.
- Increased strength: By targeting the biceps in a controlled and isolated manner, lever preacher curls can help improve overall arm strength, which can have carryover benefits for other exercises and activities.
Overall, lever preacher curls are an excellent addition to any arm workout routine, and can help you achieve bigger, stronger, and more defined biceps over time.
Lever Preacher Curl – Muscles Worked
Target - Brachialis
Synergists - Biceps Brachii
Synergists - Brachioradialis
Stabilizers - Wrist Flexors
Brachialis: The brachialis muscle is located in the upper arm, between the biceps and triceps. It is responsible for elbow flexion and is heavily recruited during the lever preacher curl due to the position of the arms.
Biceps Brachii: The biceps brachii is a two-headed muscle that runs from the shoulder to the elbow. It is responsible for flexion at the elbow and supination of the forearm. During the lever preacher curl, the biceps brachii acts as a synergist to the brachialis.
Brachioradialis: The brachioradialis is a forearm muscle that helps to flex the elbow. It also assists in pronation and supination of the forearm. During the lever preacher curl, the brachioradialis works alongside the other muscles to aid in elbow flexion.
Wrist Flexors: The wrist flexors are a group of muscles located in the forearm that are responsible for flexing the wrist. During the lever preacher curl, these muscles work to stabilize the wrist, which helps to maintain proper form throughout the exercise.
By targeting these specific muscles, the lever preacher curl is an effective exercise for building strength and size in the upper arms. It can be incorporated into a comprehensive workout routine alongside other exercises for the biceps, triceps, and forearms to help develop well-rounded arm strength and definition.
