Note : It's good to vary your grip, ie neutral, pronated & supinated grip - Shown here with a pronated grip.
Grip a light resistance band, hands about shoulder width apart.
Start with your arms extended in front of you, about chest height, and approximately shoulder width apart.
Pull the band apart by retracting your scapula (pinch your shoulder blades together), squeeze your back at the top of the movement, arms in line with your torso.
Return to the start with control. Repeat for Repetitions.
Keep the shoulders depressed (Down, away from the ears, don't allow them to shrug upward)
