Pattern
Elbow extension
Setup
- 01Set an incline bench at 30 to 45 degrees under the Smith bar.
- 02Position the bench so the racked bar sits above your face at arm's length.
- 03Grip the bar with a shoulder-width or slightly narrower overhand grip.
- 04Unhook the bar and press it to a position above the forehead with arms extended.
Execution
- 01Bend only the elbows to lower the bar toward the top of the head.
- 02Keep the upper arms angled slightly back and as still as possible.
- 03Lower until a deep stretch is felt in the triceps.
- 04Extend the elbows to return the bar along the rail to the start.
Checkpoints
- -Upper arms stay fixed; movement is only at the elbows.
- -The bar travels toward the top of the head, not the chest.
- -Wrists stay neutral rather than bent backward.
- -The lowering phase is slow and controlled near the face.
Common mistakes
- -Letting the elbows drift forward and turning it into a press.
- -Positioning the bench so the fixed path collides with the face.
- -Loading too heavy and cutting the stretch short.
- -Flaring the elbows wide under fatigue.
Programming notes
- -Use 3 to 4 sets of 8 to 12 reps with strict control.
- -The incline lengthens the triceps long head; prioritize stretch over load.
- -Set the hooks and safeties so the bar can be caught above the face at any point.
