An isolation neck strengthening exercise performed while lying on your back using a weighted head harness. The movement involves flexing the neck by slowly bringing the chin toward the chest against resistance, then returning to a neutral position with controlled motion. The body remains stable throughout to isolate the neck flexor muscles, and the exercise emphasizes slow, deliberate repetitions to maintain continuous tension through the anterior neck across the full range of motion.
Log your weighted lying neck flexion (with head harness) sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
