Major Muscles and Actions Involved
In back raises, the erector spinae and the deep back muscles are involved in extension-hyperextension. In this action the trunk is raised to the horizontal or slightly above horizontal position from an inverted vertical hanging position.
Muscles in Action
The erector spinae muscle is very important in most sports, even though it may not directly participate in moving the spine in extension or hyperextension. It must be strong enough to hold the vertebrae (spine) in place and rigid when you execute many skills, especially those involved in lifting. For example, the erectors are most important in keeping the spine in lordosis during the squat, good morning, and deadlift exercises.
