Final answer:
Hyperflexion exercises that should be avoided include hands-behind-the-neck sit-up, bicycle or shoulder stand, and deep knee bend.
Step-by-step explanation:
Hyperflexion exercises result in too much flexion in a joint, which can lead to joint injury. Some hyperflexion exercises that should be avoided include:
Hands-behind-the-neck sit-up: This exercise involves placing your hands behind your neck while doing sit-ups, which can put excessive strain on the neck and lead to hyperflexion.
Bicycle or shoulder stand: These exercises involve bending the neck or spine in a rounded position, putting stress on the joints and potentially causing hyperflexion.
Deep knee bend: While deep knee bends can have benefits for the lower body, excessive flexion in the knee joint can lead to injury.
To prevent hyperflexion injuries, it's important to perform exercises with proper form and avoid excessive flexion at the joints.
