Neck Curl

Move · Resistance Training · Movement, Typed Supps

Your head already weighs about as much as a bowling ball, so lying with it unsupported is a real load before any plate is added.

Stage by stage

Set-up (Head weight is the load): Supine with the head unsupported off the bench; four to five kilograms of head is already resistance for untrained cervical flexors.
During the set (Chin tuck, not head lift): Leading with a chin tuck biases the deep segmental flexors; a raw head lift lets sternocleidomastoid translate the head forward instead.
Immediately after (Small muscles fatigue early): Physiological cross-sectional area here is small, so loads stay low, fatigue arrives fast, and early soreness is common.
Weeks later (Cervical strength and stiffness): Strength and modest size build over months; the link to lower head and neck injury rates is observational, not proof of concussion prevention.

Muscles trained

Primary: neck

Intensity

3.5 METs (Resistance (weight) training, multiple exercises, 8-15 repetitions at varied resistance).

Time to effect

Weeks: The neck flexors are small and unaccustomed to direct loading for most people, so early sessions often bring noticeable soreness and quick improvements in how long you can hold the contraction.
Months: Genuine strength and modest size gains in the front neck muscles build up over a couple of months of consistent, progressively loaded work, similar to any other small muscle group.

Common myth

"Only wrestlers, boxers, and football players need to train their neck." In reality: Research on athletes in contact and combat sports has linked greater neck strength to a lower rate of neck and head injuries, and the same reasoning - a stronger, more fatigue-resistant neck absorbs and resists sudden forces better - applies to anyone concerned about cervical spine health, not only competitive athletes.
