Stand with your feet hip-width apart and a slight bend in your knees. Hold a dumbbell in each hand, palms facing out. Let the dumbbells rest by your sides. Roll your shoulder blades back and down your spine. This is your starting position.
Keeping your elbows close to your sides, slowly raise the dumbbells up so your arms are bent at a 90-degree angle.
Extend your arms out long in front of you, angled slightly up toward your shoulders (like you're holding a platter and serving it to someone in front of you). Keep your core tight.
Slowly bring your arms back to a 90-degree angle, and lower them down to your sides.
This counts as one rep. Continue with this exercise for one minute.
