Stand up straight with feet at shoulder-width apart, hold one dumbbell in each hand, keep your arms extended and raise the dumbbells together to your sides until your torso and arms form the T shape, now your arms are parallel to the floor and perpendicular to your torso, palms facing forward. That is your starting position
Keep your upper body erect and arms straight with a slight bend at elbows but locked. Remove your arms in a semicircular motion and bend your knees to squat down until dumbbells are in front of your head touching each other and palms become to facing down
Return dumbbells back in the same semicircular motion and stand up at the same time
Tips:
You should keep your arms extended and parallel to the floor during the process
When you squat down, you should not let your knees go past your toes
