A strong core is the foundation of a healthy body because it plays an important role in supporting the spine and enabling pain-free movement. 

Gianna Webbe, a gymnast and strength coach at The Project PT, says: "A strong core can better transfer forces to the lower limbs, which can enhance movement, strength and speed. By contrast, a weak core can be a contributor to back pain."
