Wear fitted clothes so you can see the curves of your body. First, take a pose, without shoes, with your feet shoulder-width apart having a relaxed straight torso.
Secondly, relax deeply and let your breath in its natural flow.
Now, you need another person or a friend to observe your body. It would be a good idea to take a full body photo of you from all angles, front – back – right – left. The picture will help you observe your body in all dimensions. Moreover, you will have a reference to check the differences in your posture after a particular therapeutic or strengthening program.
Furthermore, after making observations, look at the types above to discover which of these postures look like yours. For example, if you have a kyphotic thoracic curve (a hump in the back), you are likely to be of the kyphosis or sway-back posture type. Now, look at your notes about your pelvis. If your pelvis tilts backward, then you belong in a sway-back posture. But if your hips are closer to each other, then you belong to the kyphotic posture.
When you get your self-diagnosis, you can turn to an expert trainer to work together to correct your posture.
Extra tip
If you have physical pains, lack energy, and find it difficult to do daily activities, it is essential to check your posture type. In any case, Pilates and physical therapy like Bowen are the techniques that will help you return to a state of health and wellness.
