Which mat exercises are contraindicated for individuals with neck problems?

The choice that identifies Control Balance, Roll-Over, and Jackknife as contraindicated for individuals with neck problems is based on the understanding of how these exercises place stress on the neck and cervical spine.

Control Balance requires significant shoulder and neck stability, along with the ability to maintain proper alignment while balancing on the shoulders. This can strain the neck for those with existing issues. Roll-Over involves lifting the legs overhead, which can also put excessive pressure on the neck if the head is not properly supported, potentially aggravating any pre-existing neck conditions. The Jackknife, similar to the Roll-Over, involves lifting the hips and legs while maintaining a specific position that necessitates engagement of the neck muscles, which can be problematic for those with neck issues.

In contrast, while Criss-Cross and Chest Lift do involve some level of neck engagement, they typically allow for better head and neck alignment when performed correctly. The same applies to Chest Lift and Teaser; these exercises can be modified to reduce strain on the neck. Therefore, the selection of the first option is appropriate as those specific exercises present a higher risk for individuals dealing with neck problems.
