Stand with your feet shoulder width apart and lift both arms straight out to your sides at shoulder height.
Move your arms in a circular pattern, 4-6 inches in diameter with your palms facing down, drawing a small circle with your fingertips. Continue for one minute.
Let your arms relax for a few seconds, then raise them again, this time drawing the shape in the opposite direction for one minute.
For an added challenge repeat the motion for one minute in each direction, this time with your palms facing upwards.
This bodyweight exercise, though extremely simple in nature, is actually a deceptively difficult and effective move. It targets the shoulder area to increase endurance, tone and definition, all without adding bulk to the muscles involved. If you are short on equipment, this is an easy and effective training movement for your upper body home workout routine.
Remember that you can do the motion in opposite directions in order to make the move harder and put more demand on your upper body muscles.
