  1. Stand up and extend your arms straight out by the sides. The arms should be parallel to the floor and perpendicular (90-degree angle) to your torso. This will be your starting position.
  2. Slowly start to make circles of about 1 foot in diameter with each outstretched arm. Breathe normally as you perform the movement.
  3. Continue the circular motion of the outstretched arms for about ten seconds. Then reverse the movement, going the opposite direction.

Tip: Ten second movements equal one set and each circle equals one repetition.

Variations: As you get stronger you can use some light resistance.
