Description

Spider curl focuses on controlled movement and maintaining proper body alignment throughout the exercise. The goal is to create tension where needed while avoiding unnecessary strain or momentum. This helps improve movement quality, joint stability, and overall physical control.

Instructions:

  1. Start out by setting the bar on the part of the preacher bench that you would normally sit on. Make sure to align the barbell properly so that it is balanced and will not fall off.
  2. Move to the front side of the preacher bench (the part where the arms usually lay) and position yourself to lay at a 45 degree slant with your torso and stomach pressed against the front side of the preacher bench.
  3. Make sure that your feet (especially the toes) are well positioned on the floor and place your upper arms on top of the pad located on the inside part of the preacher bench.
  4. Use your arms to grab the barbell with a supinated grip (palms facing up) at about shoulder width apart or slightly closer from each other.
  5. Slowly begin to lift the barbell upwards and exhale. Hold the contracted position for a second as you squeeze the biceps.
  6. Slowly begin to bring the barbell back to the starting position as your breathe in. .
  7. Repeat for the recommended amount of repetitions.

Exercise FAQ

What should I focus on to keep good form?

Move with control and keep your torso stable. Use a range of motion you can own, and stop the set if you need momentum to finish reps. Think of it as curling done with repeatable, clean reps.

What’s the safest way to progress over time?

Add a small amount of reps first, then load. If technique slips, step back and rebuild with cleaner reps.

How should I program this in a workout?

Use it after your warm-up when you’re fresh. Aim for 2–4 sets and choose a rep range that matches your goal (strength: lower reps; muscle: moderate reps).
