What is an average trunk lift?

An average trunk lift refers to a fitness assessment that measures the strength and flexibility of the lower back and core muscles. Typically, it involves lying face down and lifting the upper body off the ground while keeping the legs in contact with the floor. The average performance can vary based on age, gender, and fitness level, but a common benchmark is lifting the upper body approximately 12 to 16 inches off the ground for a few seconds. This assessment is often used in physical education and health screenings to evaluate overall physical fitness.
