The Claim

Does the type of preacher curl (cable vs. barbell) affect strength gains at mid-range or fully bent elbow positions?

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Cause and effect

In plain English

When you do preacher curls for 10 weeks, your strength in the middle and fully bent positions gets better no matter if you use a cable or barbell — the resistance pattern doesn’t make a difference there.

See the scientific wording

In young, untrained adults, 10 weeks of preacher curl training improves elbow flexion strength at 60° and 100° of elbow flexion regardless of whether peak torque is applied at short or long muscle lengths, with no significant difference between cable and barbell methods, suggesting that strength gains at mid- and end-range positions are not torque-position dependent.

What the research says

1 study

  1. Study: Placing Greater Torque at Shorter or Longer Muscle Lengths? Effects of Cable vs. Barbell Preacher Curl Training on Muscular Strength and Hypertrophy in Young Adults

    Both cable and barbell preacher curls made people stronger at bending their elbows halfway and all the way, no matter which method they used — so the type of equipment didn’t matter for those positions.
