What is a good sit and reach score?

For an adult man, +6 to +16 cm past toes is good and +17 cm and above is excellent. For an adult woman, +11 to +20 cm is good and +21 cm and above is excellent. Most untrained adults score within 5 cm of their toes (positive or negative).

How do I do the sit and reach test at home?

Sit on the floor, legs straight, feet against a wall. Reach forward as far as you can, holding for 2 seconds at maximum reach. Measure how far past your toes (or short of) your fingertips land. Take the best of three attempts.

Is the sit and reach test accurate?

Reasonably so for hamstring flexibility. It's used in research and athletic testing. But it doesn't isolate hamstrings, your score is a combination of hamstring, lower back, and hip mobility. Two people with the same score can have very different mobility profiles.

How can I improve my sit and reach score?

Daily static hamstring stretching (3-5 min after workouts), 2-3 sessions per week of Romanian deadlifts with full range of motion, and PNF stretching once or twice weekly. Most adults see 5-10 cm improvement in 4-6 weeks of consistent work.

Why is my sit and reach so low?

Likely a combination of tight hamstrings, restricted lumbar flexion, and limited hip mobility. Heavy lifting without dedicated mobility work shortens hamstrings over time. Sedentary work (long sitting hours) also reduces hip flexibility. Both can be reversed with 4-6 weeks of dedicated stretching.

Does flexibility predict injury risk?

The research is mixed. Extreme hypermobility and severe inflexibility both correlate with higher injury rates. Moderate-to-good flexibility (around average to excellent on sit-and-reach norms) shows little correlation with injury risk in healthy adults. Mobility quality (full ROM under load) matters more than passive flexibility.

How often should I retest?

Every 4-6 weeks if you're actively training mobility. Every 3-6 months as a general check-in. Score variance day-to-day is 2-5 cm depending on warm-up, time of day, and recent training, so don't read too much into single tests.

Should I stretch before or after the test?

Both. Warm up with 5 minutes of light cardio, then do dynamic leg swings before testing. Pre-testing static stretching can artificially inflate scores by 2-4 cm, so for true baseline, do dynamic warm-up only. For maximum performance score, include static stretching in your warm-up.

Is the sit and reach better than other flexibility tests?

It's the most standardized and easiest to administer. For comprehensive mobility assessment, combine it with active straight-leg raise (per leg), Thomas test (hip flexor length), and shoulder mobility tests. No single test captures all dimensions of flexibility.

Sit and Reach Test: How to Do It, Score Yourself, and Improve

One sit. One reach. 60 seconds. The sit and reach test gives you a number for posterior chain flexibility, and tells you exactly how mobile you actually are.

The sit and reach test is the most common flexibility assessment used in PE classes, athletic combines, and physical therapy. It measures combined hamstring and lower-back range of motion. Quick to do, easy to score, and useful as a baseline you can retest every 4-6 weeks to track mobility changes.

How to Perform the Test

Equipment

A flat floor or a bench
A measuring tape or ruler
(Optional) a sit-and-reach box, which has a built-in measurement scale at foot level

Standard Protocol

Warm up with 5 minutes of light cardio + dynamic leg swings. Cold testing produces lower scores than your true range.
Sit on the floor with legs straight, feet flat against the wall (or against a sit-and-reach box).
Place one hand on top of the other, fingers extended, palms down.
Slowly reach forward as far as you can. Don't bounce. Don't bend your knees.
Hold the maximum reach for 2 seconds at the furthest point.
Measure how far past your toes (or short of your toes) your fingertips reach.

Recording

The standard reference point is your toes:

If your fingertips pass your toes by X cm, that's your positive score (e.g., +12 cm)
If your fingertips fall short, that's your negative score (e.g., −5 cm)
The toes themselves = 0 cm (zero)

Use your best of three attempts, with 30-60 seconds rest between.

Sit and Reach Norms (Adult)

Standard norms for adults (using the toes as 0), per Topend Sports:

Men

Category	Score
Excellent	+17 to +27 cm
Good	+6 to +16 cm
Average	0 to +5 cm
Fair	-8 to -1 cm
Poor	-20 to -9 cm

Women

Category	Score
Excellent	+21 to +30 cm
Good	+11 to +20 cm
Average	+1 to +10 cm
Fair	-7 to 0 cm
Poor	-15 to -8 cm

Most untrained adult men score around 0 (touching toes). Most untrained adult women score around +5 cm past toes. Scores above +27 cm (men) or +30 cm (women) are exceptional and typical of dancers, gymnasts, and yoga practitioners. Norms vary slightly by source and age, these are general adult ranges.

What Your Score Tells You

The sit-and-reach test combines:

Hamstring length (the limiting factor for most adults)
Lumbar spine flexion
Some hip mobility
Pelvic tilt range

Below average suggests one or more is restricted enough to limit movement quality. Most lifters score below average because heavy hip-hinge work (deadlifts, squats) shortens the hamstrings if you don't address mobility.

Average to good is typical for the general adult population.

Excellent is common in dancers, gymnasts, yoga practitioners, and people who do dedicated mobility work.

What the Test Doesn't Measure

The sit-and-reach is NOT:

A measure of injury risk (research is mixed on this)
A measure of "functional flexibility" (it only tests forward flexion in one position)
The whole picture of hamstring length (many people compensate with lumbar flexion)

If you score well but still feel tight in daily movement, you might be substituting lumbar flexion for hamstring length. The opposite is also possible: short hamstrings but excellent thoracic and hip mobility.

For a complete mobility picture, also test:

Active straight leg raise (each leg individually)
Squat depth (full bottom position without heels lifting)
Shoulder mobility (shoulder flexion and external rotation)

How to Improve Your Score in 4-6 Weeks

Daily

3-5 minutes of static hamstring stretching after any leg workout:

Standing forward fold: 60 sec hold × 2-3 sets
Single-leg seated stretch: 60 sec per side × 2 sets
Lying single-leg stretch with band assist: 60 sec per side × 2 sets

2-3 times per week

Loaded mobility work:

Romanian deadlifts: 3 × 10 with controlled tempo. RDLs train hamstring flexibility under load, which produces more lasting mobility than static stretching alone.
Jefferson curls: 3 × 8 (advanced). Slow controlled spinal flexion under light load.

Every session

PNF stretching (proprioceptive neuromuscular facilitation): contract the muscle being stretched for 6 seconds, then deepen the stretch. Faster gains than static stretching alone.

After 4-6 weeks, retest. Most adults gain 5-10 cm with consistent daily work.
