Start by lying on your back on a yoga mat, holding one end of a dumbbell in both hands. Bend your knees and place your feet flat on the mat, ensuring that they are hip-width apart.
Extend your arms to hold the dumbbell directly above your chest, keeping a slight bend in your elbows.
Inhale, and without letting your back arch, draw the dumbbell backward and over your head in an arc-like motion until the dumbbell is almost touching the floor.
Exhale to draw the dumbbell upward and forward in the same arc-like motion until it's directly over your ribs. Repeat for 30 seconds.
