The posture scan does not measure thoracic kyphosis, lordosis, or flat-back posture directly. This exercise may still help mobility and strength that support overall alignment — it is wellness education, not a diagnosis.

How to do it
- Lie face down, and place a tennis ball on the abdominals beside the belly button to target the psoas major muscle (which lies under the abdominals).
- Scoot your body to move the ball to any sore spots all the way down from beside the belly button to the top of the hip.
Form cues
- Internally rotate the leg (i.e., turn the foot in) to help stretch the hip flexors while performing this exercise.
- Caution: If you feel a pulse under the tennis ball, simply move the ball slightly to reduce pressure on the femoral artery.
