Why flexibility matters beyond sport
Trunk flexibility correlates with arterial flexibility in research studies and with the everyday ability to bend, tie shoes and pick things up without strain. It fades about a centimeter every few years without practice.
Measuring
Sit with soles against a box or wall edge, exhale and slide the hands forward slowly. Record centimeters past the toes as positive and short of them as negative.
Understanding your result
Zero or slightly positive means you match the age expectation. Ten centimeters or more ahead means your flexibility is that of a younger adult, while a negative score shows room to gain.
Gaining range
Ten minutes of daily hamstring, hip and back stretching typically adds several centimeters within eight weeks at any age.
