The study was done in USA (North Texas) and it involved 526 participants aged 20 to 83. While they were trying to touch their toes their blood pressure was measured and the arteries and heart activity was closely observed. Finally, it was confirmed that participants with heart disease couldn’t touch their toes. This research found a link between the body and the artery elasticity, especially in participants over 40.
Try this method and if you can touch your toes while sitting straight, your heart is in still in a good condition. But if you cannot it might be time to visit your cardiologist.
