What common mistake should be avoided during the "Short Box" series?

Overarching or flattening the lower back during the "Short Box" series can compromise the integrity of the exercise and lead to ineffective movement patterns or potential injury. This series aims to promote proper spinal alignment and core engagement, which are essential for effective training.

When the lower back is either excessively arched or excessively flattened, it can result in strain on the lumbar spine and fail to engage the desired muscle groups effectively, particularly the abdominals and back extensors. Maintaining a neutral spine is crucial in this exercise to ensure that the muscles are activated appropriately, ultimately enhancing stability, strength, and control throughout the movement. This focus on alignment helps ensure the participant gains the most benefit from the exercise while minimizing the risk of discomfort or injury.
