Concentration curl alternatives

Dumbbell, cable and machine preacher curls provide another supported-arm curl. A standing dumbbell curl is an option when a seated support setup is unavailable.

The original curls one arm at a time with the upper arm against the inner thigh. A preacher pad changes shoulder position and support, and two-arm versions change how you count and load the set.

Two-frame anatomical illustration of a seated dumbbell concentration curl. A man leans forward on a flat bench with his right upper arm braced against his inner thigh and his free hand on the other leg. In the left frame the working arm hangs almost straight with the dumbbell below the knee; in the right frame the elbow is bent and the dumbbell is curled toward the shoulder. The front of the working upper arm is shaded red.

    Machine preacher curl

    You need: Seated preacher-curl machine with upper-arm pad and handles

    Why it fits
    Offers elbow flexion with upper-arm support and a guided handle path.
    What changes
    Both arms rest on the machine pad instead of one arm on a thigh. Set the seat and use the controlled bottom range in the guide; the stack is not a dumbbell-weight conversion.

How we choose replacements

These are curated alternatives, chosen for the movement and the job the exercise does in a workout. A shared muscle group is not enough. Read what changes before choosing: support, range of motion, balance and resistance can all differ. If your goal is to improve a specific lift, alternatives do not replace practice of that lift.
