Which of the following is an early warning sign of overexertion during mobility training?

• A. Headache
• B. Excessive fatigue
• C. Nausea
• D. Back pain

Answer: (B)

Excessive fatigue is the clearest early warning that you’re overdoing it during mobility training. When you push beyond what your conditioning allows for the current effort, your muscles feel heavy, your form starts to break down, and you can’t sustain movements with the same control. This signals your body is nearing its safe limit, so it’s wise to slow down, shorten the set, or pause to recover. Other options like headaches, nausea, or back pain can happen for reasons such as dehydration, poor hydration, tension, or technique issues, but they’re less reliable as the immediate early sign of overexertion. Fatigue directly reflects the body’s response to current exertion and is a practical cue to adjust intensity.
