NAPFA Sit-and-Reach

What does the sit-and-reach station test?

MOE's NAPFA item list describes sit-and-reach as the test of forward trunk flexibility. You sit on the floor with legs straight and feet flat against a box, place one hand over the other, and reach forward along the measuring scale as far as you can, holding the position. Bending a knee or bouncing invalidates the attempt. The scale reading, in centimetres, is your score.

It is one of six stations, alongside sit-ups, standing broad jump, shuttle run, pull-ups or inclined pull-ups, and the run-walk. The full station list and where the points sit is in the NAPFA test guide.

What is the standard?

NAPFA grades each station from A to E against tables set by age and gender, and combines the six into Gold, Silver or Bronze awards. For the sit-and-reach an A takes more than 39cm at 12 for boys and girls, rising to more than 48cm for boys and 46cm for girls by 17. Train to the grade above your current one.

MOE does not post the NAPFA grade tables on moe.gov.sg, so the figures below are copied exactly from the secondary standards that Dunman Secondary School publishes (checked 24 Oct 2026). Each grade earns 5 points for an A down to 1 for an E.

Gold needs at least a C on all six stations and 21 points, Silver a D on all six and 15, Bronze an E on all six and 6. Distances are in centimetres, from the better of two attempts with a floating zero point. The primary sit and reach bands for ages 9 to 13 are in NAPFA standards for primary school.

Two facts hold across every table. First, sit-and-reach is graded on a narrow range, so a few centimetres often moves a grade. Second, the gap between a D and a B is usually smaller than a semester of sitting through tuition and CCAs takes away, which is why students who were flexible in Primary 4 arrive at Secondary 4 unable to touch their toes.

Why do hamstrings and hips limit the score?

To reach past your feet with straight legs you must fold at the hips, and the hamstrings run from the sit bones to below the knee, so they are stretched by both the straight knee and the hip fold. Short hamstrings stop the pelvis tipping forward, and the spine tries to make up the distance by rounding, which adds very little reach and loads the lower back.

Hours of sitting shorten the hip flexors and stiffen the hamstrings. That is the pattern in most secondary students and in most desk-bound NSmen. Runners are often worse because running keeps the hamstrings tight without taking them through their full length. So the fix is not more back bending. It is longer hamstrings and a hip that can hinge.

A quick home check tells you which it is. Lie on your back, keep one leg flat, and lift the other straight up with the knee locked. If it stops well short of vertical, the hamstring is the limit and the plan below is for you.

If it goes past vertical but you still cannot reach your toes sitting, you are rounding the back instead of tipping the pelvis, and the hip hinge drills matter more than the stretches. Most students are the first case. Some who play football or run cross-country are the second.

What does a 4-week mobility plan look like?

Five to eight minutes a day, done warm: hamstring and hip-flexor stretches in week 1, a wall hinge drill and 90/90 added by week 3, then a held reach in the test position and a mock in week 4.

1. 01Warm firstTwo minutes of marching, leg swings or a slow jog before any hold. Cold stretching does little and hurts.
2. 02Breathe out into the stretchEase into the last few centimetres on the exhale rather than forcing them.
3. 03Keep the knees straightA bent knee lets the hamstring off and trains the wrong pattern.
4. 04After the run, not beforeLong static holds before running blunt power and can raise injury risk. Do them at the end of the session.
5. 05Every dayFive minutes daily beats thirty minutes on Sunday. Flexibility is about frequency.

None of this needs equipment or space beyond a mat in the living room, so it is the easiest station to keep going through exam weeks and CCA season. Attach it to something that already happens daily: after the evening shower when the muscles are warm, or the last five minutes after a run at the park connector.

Measure the reach once a week in the test position, with a ruler taped to a step or a box, and write it down. Students who see the number move keep doing the work.

How should you warm up on test day?

Move for five minutes before you sit down: a slow jog, leg swings front and side, walking lunges and a few bodyweight squats. Then do two or three gentle practice reaches, each held for a couple of seconds, before your scored attempt.

Warm muscles lengthen further, so never take the station cold, and a warm-up is what HealthHub's injury-proofing advice asks for too, and if sit-and-reach comes early in the test order, warm up specifically for it.

On the attempt itself, breathe out, fold from the hips, keep the knees pressed down, and slide the hands forward slowly. A slow reach goes further than a lunge and does not trigger the knee-bend that invalidates it. Ask the tester to confirm your reading before you release.

Which faults cost centimetres or void the sit-and-reach?

Two faults void the attempt outright: a knee that lifts off the floor and a bounce or lunge at the end of the reach. The rest cost centimetres, and on a station graded over a narrow range a few centimetres is often a full grade. Each fault below has a fix you can practise in the 4-week plan.

Who should be careful with this station?

Anyone with a current lower back injury, sciatica-type leg pain, or a recent hamstring strain should get cleared by a doctor or physiotherapist before doing loaded forward folds, and should not force the reach on test day.

Sharp pain, numbness or tingling down a leg is a reason to stop, not stretch harder. For everyone else, the plan above is low risk because the loads are bodyweight and the holds are gentle.

Is it worth coaching a flexibility station?

Rarely on its own, but it is the easiest station to fold into a full NAPFA or IPPT block. When we coach a student or pre-enlistee at home or in the condo gym, the last five minutes of every session is hamstring and hip work in the test position, so the cheapest points are never left behind. Pull-ups and the run take the other 55 minutes. See pull-ups and sit-ups and IPPT and NAPFA coaching.
