1. Stand upright with your feet together and breathe out naturally.

2. Find your natural waistline, which is the narrowest area between your ribcage and hips.

3. Measure your waist:

• If using a tape measure, wrap it around your waist, keeping it level with the floor.
• If you don’t have a tape measure, use a string, mark where it meets, and measure that length with a ruler.

4. Take the measurement after a normal exhale, without pulling in or pushing out your stomach.
