Question

explain the procedure of spine flexiblity test in details

Answer 1

The sit and reach test is the most common way to measure lower back and hamstring flexibility.

Because tightness in the low back and hamstrings is often related to muscle pain and stiffness, this test may help determine a person's risk for future pain and injury. It has been used by exercise physiologists and fitness trainers for decades to assess baseline flexibility before starting an exercise program and is repeated after several weeks to determine progress. Because it's been around so long, it has a pretty large database of results across all age groups and genders. For this reason, people continue to use it to compare a person's flexibility to the average result for their gender and age group.
