Pattern
Horizontal adduction
Setup
- 01Set a decline bench to roughly 15 to 30 degrees.
- 02Hook the feet under the pads and lie back.
- 03Press the dumbbells up over the lower chest.
- 04Turn the palms to face each other.
Execution
- 01Lower the dumbbells out in a wide arc.
- 02Keep a fixed, slight bend in the elbows.
- 03Stop when you feel a full chest stretch.
- 04Squeeze the pecs to sweep the arms back together.
Checkpoints
- -Elbow angle stays constant; this is not a press.
- -The dumbbells stay over the lower chest line.
- -Shoulder blades stay pinned to the bench.
- -The stretch stops at shoulder level, not below.
Common mistakes
- -Bending and extending the elbows, turning it into a press.
- -Dropping too deep and straining the shoulder joint.
- -Banging the dumbbells together at the top.
- -Using loads too heavy to control the arc.
Programming notes
- -Use 3 sets of 10 to 15 reps with lighter loads.
- -A 3 second lowering maximizes the stretch stimulus.
- -Progress by adding reps before adding weight on flys.
