You lie face up on a flat bench with your head completely off the end of the bench, arms crossed over your chest, and curl your chin toward your chest before lowering your head back down under control. Because only the weight of the head provides resistance, it is one of the safest ways to load the neck directly. This movement is useful for almost anyone. Contact sport athletes such as wrestlers, rugby players, and boxers use it to build a stronger, more resilient neck. Office workers and drivers who spend long hours with the head drifted forward often benefit from it as well, since weak deep neck flexors are common in people with a forward head posture. It also pairs well with Lying Neck Extension to train the front and back of the neck evenly. The setup matters more here than in most exercises. Your shoulders and upper back must rest fully on the bench while your head hangs free past the edge. If your head is still partly supported, you shorten the range of motion; if your shoulders slide off the bench, you lose stability and turn the movement into an awkward partial crunch. Feet flat on the floor with knees bent keeps the torso steady so the work stays in the neck. To perform it well, think of nodding first and then curling. Start the rep by tucking the chin, then let the head continue toward the chest until you feel the front of the neck fully shortened. Lower slowly, letting the head travel slightly past neutral at the bottom for a light stretch, but do not let it drop or hyperextend. The entire rep should feel smooth and quiet, with no jerking at the start. Keep the range honest and the tempo slow. The neck responds better to controlled, moderate work than to aggressive loading, and this variation gives you that without any equipment beyond a bench. Start with higher repetitions and only add resistance later, once the movement feels easy and completely stable. ## Instructions 1. Lie face up on a flat bench with your upper back and shoulders fully supported and your head extending past the end of the bench. 2. Bend your knees and place your feet flat on the floor to stabilize your torso. 3. Cross your arms over your chest and let your head hang relaxed at the level of your spine. 4. Brace your upper back lightly against the bench so your torso stays fixed throughout the set. 5. Nod your chin toward your chest to start the rep, then curl your head up until you feel the front of the neck fully contracted. 6. Pause briefly at the top without pulling with your hands or lifting your shoulders. 7. Lower your head slowly back down, letting it travel slightly past neutral for a gentle stretch at the bottom. 8. Exhale as you curl up and inhale as you lower your head back down. 9. Complete your reps, then sit up carefully from the bench, turning your head gently if you feel any stiffness. 10. Rest briefly between sets, keeping the movement slow and controlled rather than rushing through repetitions. ## Tips & Tricks - The most common mistake is dropping the head on the way down. The lowering phase is where the deep neck flexors work hardest, so take two to three seconds on the descent. - Do not yank your head up by pulling on your chest or neck with your hands. Keep the arms crossed and passive so the neck muscles do the lifting. - If your shoulders creep off the bench as you curl, slide back slightly so only your head hangs past the edge. The rest of your torso should stay planted. - Start with a partial range if the full movement feels awkward. Curl halfway up for the first week or two, then extend the range as control improves. - Avoid letting the head rotate or tilt to one side. Keep your nose pointed straight at the ceiling on the way down and straight ahead at the top. - Higher repetitions in the fifteen to twenty-five range work well here, since the neck responds to moderate, consistent loading rather than max effort. - Balance your program by including neck extension work as well. Training only the front of the neck can pull your head posture forward over time. - Never bounce at the bottom or hyperextend the neck under gravity. The stretch past neutral should be brief and light, not a loaded hang. - If you feel dizziness or sharp pain at any point, stop the set and reduce the range on your next attempt rather than pushing through. ## Frequently Asked Questions ### Which muscles does Lying Neck Flexion work? It primarily trains the sternocleidomastoid and the deep neck flexors on the front of the neck, with the upper traps and surrounding stabilizers working lightly to keep the head aligned. ### Is Lying Neck Flexion suitable for beginners? Yes, because your head is the only resistance. Beginners should start with one or two sets of ten to fifteen slow reps and a comfortable range before adding volume. ### Why does my head need to hang completely off the bench? Hanging the head past the edge lets it travel through the full flexion range and gives it room to lower slightly past neutral. If the head rests on the bench, the range of motion is cut short and the muscles are underloaded. ### Should I hold a weight plate on my forehead? Not at first. Master the bodyweight version with slow, controlled reps, and only consider light added resistance once twenty or more reps feel easy and your form stays clean. ### How does Lying Neck Flexion differ from doing crunches on a bench? In a crunch your torso flexes while the head stays neutral. Here your torso stays fixed on the bench and only the head curls at the neck joint, which isolates the front of the neck instead of the abdominals. ### How often can I train this exercise? Two to three sessions per week is a sensible starting point. The neck recovers reasonably quickly at low loads, but avoid training it hard on consecutive days until you know how you respond. ### Can Lying Neck Flexion help with forward head posture from desk work? Strengthening the deep neck flexors is commonly used as part of a posture program, and this exercise trains them directly. Pair it with upper back work and regular movement breaks rather than relying on one exercise alone. ### What should I do if I feel strain on one side of my neck? Check that your head stays square and does not rotate or tilt during the rep, and reduce the range of motion. If the feeling persists, stop and have the movement reviewed before continuing. ### Can I do this exercise without a bench? Yes, you can lie on the floor or a mat, though the range at the bottom is limited by the floor. A bench gives the head room to lower past neutral, which makes the movement more complete.
