Which of the following exercises is beneficial for enhancing endurance of back extensors?

The exercise that enhances the endurance of back extensors is the prone head raise. This exercise involves lying face down and lifting the head and upper torso off the ground, which actively engages the spinal extensor muscles. These muscles are crucial for maintaining posture and supporting the spine, especially during activities that involve bending or lifting. By performing prone head raises, individuals can strengthen and improve the endurance of these back extensors, leading to better stability and reduced risk of injury in the lower back.

The other exercises listed do not specifically target the back extensors in the same way. Lateral raises primarily focus on the shoulder muscles, leg extensions target the quadriceps, and the dumbbell bench press is more centered around the chest and triceps. Therefore, while all these exercises may contribute to overall fitness, the prone head raise is specifically beneficial for developing the endurance of the back extensor muscles.
