Anatomical Execution: Stand tall with dumbbells resting against the front of your thighs, palms facing backward. Maintain a slight, fixed flexion at the elbow joint to minimize joint leverage stress.
Rest Interval: 60 seconds.
"As Frédéric Delavier instructs: Raise the dumbbell forward and upward until your arm reaches eye level, isolating the anterior head of the deltoid while keeping your torso completely rigid to prevent any swinging momentum."
