Grab a set of dumbbells and sit on a flat workout bench (or on the floor).
With one dumbbell in each hand resting on your thighs, lie back onto the bench.
Hold the dumbbells above your chest, shoulder-width apart, creating a 90-degree angle between your upper arm and forearm. Your palms should be facing away from your head.
Exhale as you push the dumbbells up, fully extending your arms. Hold for one second.
Inhale and lower the dumbbells to the sides of your chest with control. That's one rep.
