Mike Sommerfeld's Preacher Curl Tip: The Small Adjustment That Creates Better Bicep Contractions

When it comes to building bigger biceps, most lifters focus on doing more.

More sets.
More exercises.
More weight.

Elite bodybuilders think differently.

They focus on getting more out of every rep.

In a recent training session, IFBB Pro Kuba Kolinek worked through single-arm preacher curls while Mike Sommerfeld analyzed every detail of his technique. The adjustment Mike suggested was simple, but the result was immediate.

A better position.

A stronger contraction.

A more noticeable bicep split.

Why Small Adjustments Matter in Bicep Training

Many lifters assume muscle growth is only about increasing weight or adding volume.

While progressive overload matters, execution matters too.

Small changes in elbow position, arm alignment, and muscle engagement can completely change how an exercise feels.

That is why professional bodybuilders spend so much time refining technique.

The goal is not simply moving the weight.

The goal is maximizing tension in the target muscle.

The Preacher Curl Advantage

The preacher curl has long been one of the most effective exercises for bicep development because it limits momentum and helps isolate the biceps throughout the movement.

When performed correctly, preacher curls can help improve:

• Bicep isolation
• Mind-muscle connection
• Training efficiency
• Peak contraction
• Arm development

The difference between an average rep and a great rep often comes down to execution.

Elite Athletes Focus on Precision

Watching athletes like Mike Sommerfeld and Kuba Kolinek train reveals a common theme.

They are not chasing random reps.

They are chasing quality reps.

Every adjustment has a purpose.

Every movement is intentional.

Every contraction matters.

This level of precision is one of the reasons elite athletes consistently produce world-class physiques.
