Is the Bridge with knee extensions considered a beginner move due to its impact on the low back?

The Bridge with knee extensions is not considered a beginner move primarily due to the added complexity and demands it places on the body, especially regarding core stability and coordination. This exercise engages multiple muscle groups, including the glutes, hamstrings, and core, while requiring a level of balance and control that may not be fully developed in beginners.

Additionally, the knee extensions introduce a dynamic aspect to the bridge, increasing the challenge for the low back and core. For individuals who are still mastering foundational movements or who may have not yet built adequate strength or stability, the exercise could potentially lead to unwanted strain or compromise form.

While it is important to be mindful of modifications and individual capabilities, this move generally aligns more appropriately with an intermediate to advanced skill level.
