NASM CPT Practice Exam 2025 – Complete Guide for Certification Preparation

Flexibility training primarily focuses on enhancing the range of motion in the joints and improving the overall extensibility of muscles. This process involves stretching exercises that elongate the muscle fibers, making them more adaptable to various movements. Improved muscle extensibility leads to better performance in physical activities by allowing muscles to stretch more readily and efficiently during movement, reducing the risk of injuries and enhancing overall physical performance.

The other options do not represent benefits of flexibility training. Increased muscle soreness results from intense workouts or overuse rather than stretching, and decreased joint range of motion conflicts with the fundamental purpose of flexibility training. Similarly, a decreased functional length of muscles would result in less effective movement and performance, which is contrary to the goals of flexibility training. Thus, the correct answer highlights the positive outcomes associated with flexibility exercises.
