Lying Chin Tucks is a beginner bodyweight exercise for the deep cervical flexors (longus colli, with the longus capitis) assisting. Most lifters train it for 2 to 3 sets of 10 to 12 reps.
This exercise involves lying on your back and performing a chin tuck by gently drawing the head backward to create a “double chin” while keeping the back of the head in contact with the floor. The movement is slow and controlled, focusing on activating the deep neck muscles without lifting or straining the head.
Use lying chin tucks as part of a warm up, a neck and posture routine, or a daily mobility habit. Perform 2 to 3 sets of 10 to 12 reps, holding each tuck for 5 seconds, with minimal rest between sets. The exercise exists to wake up the deep neck flexors that switch off with forward head posture, not to build size.
Start with bodyweight and a gentle effort, holding each tuck for five seconds and keeping the head on the floor. Progress by extending holds to 10 seconds, then by lifting the head one centimetre off the floor while tucked, and finally by moving to the seated or standing version against a band. The most common fault is nodding the chin down instead of gliding it back; fix it by placing a finger on the chin and pushing straight back toward the floor.
Chin tucks strengthen the deep cervical flexors and lengthen the muscles at the back of the neck and base of the skull. Over time they help correct forward head posture and reduce neck tension from screen use.
Two to three sets of 10 to 12 reps with 5 second holds, once or twice a day, is a common starting dose. Consistency matters more than volume, so short daily sessions work best.
Done gently they are one of the safest neck exercises and are widely used in rehab. Stop if you feel sharp pain or dizziness and avoid forcing the head back hard.
