Pattern
Elbow flexion
Setup
- 01Set an incline bench to roughly 30 to 45 degrees.
- 02Lie chest-down on the pad with your feet planted for stability.
- 03Hold a dumbbell in one hand with a neutral thumb-forward grip.
- 04Let the working arm hang straight toward the floor.
Execution
- 01Curl the dumbbell up while keeping the palm facing your body.
- 02Bend only the elbow; the upper arm stays vertical.
- 03Pause briefly at peak flexion.
- 04Lower slowly until the arm is fully straight.
Checkpoints
- -The grip stays neutral for the entire rep.
- -The chest and hips stay in contact with the bench.
- -The elbow, not the shoulder, does all the work.
- -Each rep finishes at full extension.
Common mistakes
- -Rotating the palm up and turning it into a standard curl.
- -Kicking the upper arm forward at the top.
- -Bouncing out of the bottom position.
- -Shrugging the working shoulder toward the ear.
Programming notes
- -Use 3 to 4 sets of 8 to 15 reps per arm.
- -Pair it with a supinated curl variation to cover both grip angles.
- -Keep loads moderate; the strict prone position punishes cheating.
