Certified Personal Trainer (NSCA) Practice Exam 2025 – Complete Prep Guide

Decreased performance is a well-recognized indicator of overtraining. When an individual engages in excessive training without adequate recovery, their body can become fatigued, leading to a decline in performance across various metrics, such as strength, endurance, and overall workout effectiveness. This decline occurs because the body does not have enough time to recover and adapt to the stresses of training, resulting in what is often referred to as "overtraining syndrome." The physiological stress can lead to symptoms such as fatigue, poor concentration, and increased risk of injuries, all contributing to reduced athletic performance.

On the other hand, increased energy levels and improved recovery time are typically signs of effective training and recovery. Consistent weight loss, while sometimes a goal, can also be a complicated sign that depends largely on diet and overall health rather than solely indicating overtraining.
