Why is it important to keep the abdominal muscles tight during the Rear Lunge?

Keeping the abdominal muscles tight during the Rear Lunge is crucial for maintaining a straight back. Engaging the core stabilizes the spine and supports proper posture throughout the movement. When the abdominal muscles are contracted, they help to prevent excessive bending or arching of the back, which can lead to injury. A straight back is essential not only for safety but also for ensuring that the lunge is performed correctly, allowing for better force distribution and muscle engagement in the lower body.

In this context, while options related to flexibility, balance, and strengthening of leg muscles are important aspects of overall fitness and can also be influenced by core engagement, the primary reason for keeping the abdominal muscles tight during the Rear Lunge specifically relates to the maintenance of a straight back. This reinforces correct body alignment, which is fundamental during the lunge exercise.
