🤸 Assess Your Flexibility
What is a Flexibility Assessment Tool?
The sit-and-reach is the classic field test for hamstring and lower-back flexibility, and this tool turns your measured reach into a clear rating. It compares your result — which can be negative if you fall short of your toes — against standard thresholds, lightly adjusted by sex, and adds a recommendation.
Use it to benchmark your mobility and track improvement as you add stretching to your routine. The result is a general fitness estimate, not medical advice — the test covers only the posterior chain, so consult a doctor or qualified trainer, warm up, use proper form, and never stretch into pain.
❓ Frequently Asked Questions
How do I perform the sit-and-reach test?
Sit on the floor with legs straight and feet flat against a box or wall, then reach forward slowly as far as you comfortably can and measure how far your fingertips pass (or fall short of) your toes. Warm up first, exhale as you reach, and never bounce or force the stretch — record the best of two gentle attempts.
What does my flexibility rating mean?
The sit-and-reach measures hamstring and lower-back flexibility specifically, and your rating compares your reach against typical ranges, lightly adjusted by sex. A lower rating simply flags an area with room to improve; it doesn't measure shoulder, hip, or overall mobility.
How can I improve my flexibility?
Consistency beats intensity — a few minutes most days of gentle hamstring, hip, and lower-back stretching, eased in without pain, steadily improves range over weeks. These are general fitness estimates, not medical advice — consult a doctor or qualified trainer, warm up before stretching, use proper form, and never stretch into pain.
