Instructions
Lean forward into an incline bench
Using a neutral grip, hold a dumbbell in each hand so your palms are facing in.
Your arms should be fully extended and hanging straight down. This is the start position.
Pull your shoulder blades back and flex your elbows to pull the dumbbells up to your sides.
Hold and squeeze your shoulder and back muscles.
Return to the start position in a slow, controlled movement.
Repeat.
