Overreacting vs Overtraining: How to Tell the Difference and Protect Your Performance

When you’re training hard — whether you’re a beginner lacing up for the first time or an elite chasing podiums — your body sends constant feedback. The tricky part? Not all discomfort means you’re in trouble. Sometimes you’re just adapting. Sometimes you’re on the verge of burnout. Knowing the difference between overreacting and overtraining can save you from unnecessary rest or long-term setbacks.

1. Overreacting — The Mental Misread

Definition: Overreacting is a mental or emotional response where you interpret normal training sensations as something more serious than they are. It’s like mistaking a drizzle for a hurricane — uncomfortable in the moment, but harmless in the bigger picture.

Common Triggers:

• Feeling a little stiff and thinking you’re injured.

• Having one “off” session and deciding you’re losing fitness.

• Comparing your pace to a faster friend and assuming you’re doing something wrong.

Signs You’re Overreacting:

• Emotional frustration after a single bad session.

• Frequent plan changes based on day-to-day feelings.

• Avoiding training out of fear from minor aches.

Impact on Your Body: Minimal physical harm — but the stop-start approach disrupts training consistency.

How to Overcome It: Keep a training journal, learn what DOMS feels like, and focus on consistent work.

2. Overtraining — The Physical Breakdown

Definition: Overtraining is a physiological state caused by prolonged training stress that exceeds your body’s ability to recover. It’s not just feeling “tired”—it”’s a deep, systemic fatigue that doesn’t resolve with a single rest day.

Warning Signs:

• Ongoing fatigue even after rest.

• Declining performance despite consistent effort.

• Higher-than-normal resting heart rate.

• Mood changes: irritability, anxiety, or low motivation.

• Poor sleep quality.

• Getting sick more often.

Impact on Your Body: Hormonal imbalance, lower immune function, reduced muscle repair, and potential months of recovery.

Fixing Overtraining: Reduce training load, take a rest week, prioritise sleep, fuel properly, and manage life stress.

3. Recovery, Sleep, and Nutrition — The Big Three

Your ability to recover isn’t just about rest days — it’s about the quality of your recovery. Sleep, nutrition, and active recovery practices all play a crucial role.

• Sleep: Deep sleep boosts growth hormone production and tissue repair.

• Nutrition: Carbs restore glycogen, protein repairs muscle, and adequate calories prevent overtraining.

• Active Recovery: Gentle movement increases circulation and speeds up healing.

4. Elite vs Beginner Athletes — Who’s at Risk?

Elite Athletes: Can tolerate higher loads but often push close to their limits for long periods. Overtraining can sneak up because they’re conditioned to push through discomfort.

Beginner Athletes: Less conditioned bodies mean normal training stress can feel extreme. More likely to overreact to DOMS but still at risk for overtraining if they progress too quickly.

5. Could It Just Be DOMS?

DOMS (Delayed Onset Muscle Soreness) is a natural part of adaptation: it appears 12–48 hours after a workout, peaks at day 2, and fades within 3–5 days. Feels like a dull ache, not sharp pain.

If soreness lasts more than a week, worsens, or is paired with deep fatigue and poor performance — it may be more than DOMS.

6. Can It Affect Everyone?

Yes. Both overreacting and overtraining can impact athletes of all sports and all levels. Awareness, experience, and proper planning reduce the risk.
