Which exercise focuses on core stability and is beneficial for back extensor endurance?

The exercise that specifically focuses on core stability and is beneficial for back extensor endurance is prone head raises. This exercise targets the muscles of the back, particularly the erector spinae, which are essential for maintaining posture and providing spinal stability.

When performing prone head raises, an individual lies face down and lifts their head and upper body off the ground, engaging the back extensors while minimizing strain. This movement helps to strengthen these muscles, which support spinal alignment and stability, crucial for overall core strength.

While other exercises like planks also contribute to core stability, they engage multiple muscles of the core rather than specifically isolating the back extensors. Kettlebell swings primarily focus on dynamic strength and power with an emphasis on the lower body. Push-ups mainly strengthen the upper body and core but do not specifically target back extensor endurance.
