We all know that exercise is good for us, but too much of a good thing can sometimes be bad and may even lead to an injury. It's crucial to listen to your body's signals. There are five clear signs that you might be overdoing it with your exercise, and in this article, I'm going to reveal what those signs are and what to do about it. At Speediance, we’re passionate about helping you achieve your fitness goals safely and effectively.

Sign 1: Excessive Fatigue
So the first sign that you might be overdoing it with your exercise is excessive fatigue. Fatigue is a sign of tiredness, and it means that you're not recovering in time for your next workout. Now there are two types of fatigue we need to talk about: local fatigue and systemic fatigue.
- local fatigue:
After targeting a specific muscle group during your workout—say, putting your biceps through a rigorous session this morning—it’s completely normal to feel tiredness and weakness in that exact area for the next day or so. This localized muscle fatigue is a direct sign that you challenged the tissue effectively. It’s part of the process.
The real test is how long this localized fatigue lingers. If, several days later (think 3 or 4 days), you’re preparing to train your biceps again and they still feel heavy, weak, or depleted, it’s a warning sign. Your previous session likely exceeded the muscle’s recovery capacity. This lingering local fatigue means the muscle isn’t ready for another intense stimulus. Pushing forward not only hampers performance but also significantly increases your injury risk. Crucially, consistent progress requires matching your training frequency to a muscle's recovery speed. For instance, if you schedule quadriceps workouts for Mondays and Thursdays but arrive Thursday feeling your legs haven't bounced back from Monday's squats, you're facing local overtraining. The fatigue accumulation is disrupting your plan.
- systemic fatigue:
A distinctly different experience is systemic (whole-body) fatigue. This isn't isolated to one muscle; it feels like your entire system is dragging. Symptoms can mimic feeling rundown or even flu-like: deep, widespread achiness, stiff or tender joints, persistent sluggishness, and a noticeable loss of enthusiasm for training. This pervasive exhaustion doesn't strike suddenly. It builds gradually from consistently pushing intense workouts without providing adequate rest and recovery periods for your entire body.
Sign 2: Plateau in Strength Gains
Hitting temporary plateaus is a normal part of any training journey. You might experience a week or two where the weights feel stuck – no noticeable gains in strength or reps. Often, this resolves naturally; by the third week, you might finally squeeze out an extra repetition or add a small increment to the bar.
But prolonged stagnation tells a different story. If you’ve consistently pushed hard, maintained perfect attendance, and followed your program diligently – yet seen zero strength improvements for several weeks (think a month or more) – this isn't just a typical plateau. It’s a strong indicator you've crossed into overreaching territory.
Instead of building strength, your body is struggling to recover from the accumulated stress. The excessive workload without adequate rest turns adaptation upside down: you’re effectively losing ground, not gaining it. You're not just stalled; you're fighting against your own physiology. This persistent lack of progress, despite perfect effort, signals it’s time to reassess your recovery, not push harder.
Sign 3: Persistent Pain in Joints or Connective Tissues
Exercise should create sensations. When lifting weights, you'll likely feel a distinct working burn or ache in the primary muscles being targeted. Similarly, intense cardio might bring temporary discomfort in the lungs, diaphragm, or working leg muscles. This type of exertion-related sensation is normal, even desirable—it signals effective effort.
Crucially, this differs sharply from problematic pain. The concerning type occurs within joints or connective tissues (tendons, ligaments, fascia). Imagine performing a set of bicep curls. The desired feeling is a deep fatigue localized within the bicep muscle belly itself. What you don't want is sharp, pinching, or persistent pain focused above or below the muscle—like pain radiating through the elbow joint itself or concentrated at the tendon attachments near the shoulder or forearm.
Why is this joint/connective tissue pain a major red flag?
- Missed Target: If this kind of pain forces you to stop your set, it means the intended muscle group wasn't effectively overloaded. You stressed the support structures, not the muscle you aimed to train.
- Injury Catalyst: Experiencing this pain significantly elevates your risk of acute or chronic injury. It indicates tissues are being strained beyond their current capacity.
- Cumulative Damage: All exercise creates microscopic stress in connective tissues. This is normal and manageable if adequate rest is provided between sessions for repair and adaptation. However, consistently training without sufficient recovery allows this micro-damage to accumulate unchecked. Over time, this silent deterioration can progress from manageable irritation to significant tissue breakdown, dramatically increasing the likelihood of a debilitating rupture or tear.
- The Takeaway: Distinguishing between productive muscle fatigue and harmful joint/connective tissue pain is critical. The latter is your body's urgent alarm system. Ignoring it, especially when compounded by insufficient recovery, sets the stage for potentially severe setbacks. Later, we'll explore strategies to train effectively while respecting these vital signals.
Sign 4: Disrupted Sleep
Sleep isn't just rest - it's your body's essential repair cycle. This critical recovery phase facilitates muscle regeneration, neural restoration, and systemic healing following physical exertion. When exercise volumes push beyond sustainable limits, however, disrupted sleep often emerges as a primary warning signal.
This creates a self-perpetuating downward spiral:
Excessive training demands increase your need for deep recovery, yet simultaneously compromise your sleep quality. The consequence? Your body's repair mechanisms become impaired just when they're needed most. You may then misinterpret this accumulating fatigue as needing more training stimulus, accelerating the destructive cycle.
Watch for these specific patterns:
- Frequent unexplained awakenings during the night
- Difficulty returning to sleep after waking
- Persistent non-restorative sleep (waking unrefreshed)
- Occurring without external factors like pain or bathroom needs
When sleep fragmentation becomes your new normal despite consistent training effort, recognize this as your physiology sounding the alarm. Chronic sleep disruption directly diminishes your adaptive capacity, making continued intensive training counterproductive.
Sign 5: Loss of Motivation
Physical capacity is only half the equation in effective training. Your psychological relationship with exercise serves as critical fuel for consistency – the cornerstone of long-term results. Choosing activities you genuinely enjoy creates powerful self-reinforcement: effort feels purposeful, creating sustainable habits that transcend imperfect programming. Many achieve remarkable fitness simply through decades of joyful consistency.
However, training anhedonia presents a distinct danger. This isn't temporary reluctance; it's a profound shift where workouts transform from anticipated challenges to dreaded obligations. Key markers include:
- Persistent dread preceding sessions
- Lingering fatigue unrelated to physical exertion
- Previously, satisfying discomfort became intolerable
- Existential questioning of exercise's value ("Why is this making life worse?")
- General emotional flatness or listlessness
This represents burnout's psychological dimension – where accumulated physiological stress spills into cognitive and emotional systems. The vicious cycle intensifies as avoiding sessions breeds guilt, while forced participation deepens resentment. Recognizing this motivational collapse isn't weakness; it's your nervous system signaling unsustainable overload.
Recovery demands respecting this psychological boundary.
So now we're going to talk about how to fix these problems if you are exercising too much. It's not just as simple as having a couple of days off and mingling back; it's much more complex than that, so let's talk about the best way to reset your body.
Week 1: Complete Rest
Absolute discontinuation of all structured exercise. This means
- Zero gym sessions
- No running, cycling, swimming, or sports
- Elimination of all programmed training Permitted: Daily living activities & light movement (walking, gardening).
- Purpose: Mandatory stimulus removal enables deep-system recovery. Certain tissue repairs require uninterrupted healing windows only achievable through complete cessation. Consider this your biological reset button.
Critical Insight: Post-week energy resurgence ("I feel ready to train!") often indicates nervous system rebound, not full recovery. Significant fatigue accumulated over weeks/months won't resolve in seven days. This leads to...
Week 2: 50% Rule
Resume training modalities at precisely 50% of pre-break volume and intensity
Implementation Guide:
Resistance Training
• Reduce working weights by 50% across all lifts
• Halve total repetitions per exercise
• Decrease number of sets by 50%
• Limit session duration to ≤30 minutes
Endurance Training
• Option A: Maintain regular route at 50% normal pace
• Option B: Reduce distance by 50% at conversational pace
• Option C: Hybrid approach (50% distance + 50% pace reduction)
Critical Performance Expectations:
Upon completing these sessions, you should experience:
- Minimal muscular fatigue (<2/10 perceived exertion)
- Significant metabolic reserve post-session
- Subjective sense of "under-training"
Physiological Rationale:
This deliberate under-stimulation serves three essential functions:
- Neuromuscular Reactivation - Re-establishes movement patterns without strain
- Atrophy Mitigation - Counteracts initial detraining signals while avoiding fatigue accumulation
- Metabolic Priming - Prepares energy systems for subsequent progressive reloading
Mindset Adjustment:
Embrace the discomfort of perceived underachievement. This temporary reduction represents strategic investment in sustainable progress, not regression. The controlled exposure prepares your systems for the phased overload reintroduction to follow in week three.
Week 3: Return to Normal with Adjustments
Week three is about getting you back to your regular routine. However, we're making one significant change. Think back: to reach that point of severe fatigue, something was likely overdone. Maybe you lifted too heavy, did too many sets, or ran too far. Our goal is to identify that key factor and tweak it – not necessarily eliminating it entirely, but adjusting a single variable to gauge your body's response.
For instance, if heavy gym weights caused fatigue leading to time off, don't immediately jump back to the same heavy loads. Instead, consider starting with lighter weights and focusing on higher repetitions. Remember this key point: lifting lighter weights to the point of fatigue delivers nearly the same muscle-building results as lifting very heavy weights to fatigue, but with crucial differences: it generates significantly lower systemic tiredness and carries a slightly lower risk of injury.
The principle applies across activities:
Runners: If long distances were the issue, try shorter routes run at a faster pace. Conversely, if you were pushing speed, try longer distances at an easier pace.
The Bigger Picture: Changing your stimulus every few months is beneficial! A new challenge often accelerates improvement.
Once you've implemented this variable change, the most critical step begins: an incredibly slow progression. Rushing back is the most common mistake, leading straight back to crashes. Instead:
Increase your workload by only 2-5% every 1-2 weeks.
This could mean adding 2-5% weight to lifts, increasing running distance or pace by 2-5%, or adding a small amount of volume.
The increments should be so gradual your body barely registers the change. Sudden jumps create significant fatigue accumulation and risk setbacks.
However, here's the essential fifth point: Even with this ultra-slow build-up, pushing yourself will accumulate fatigue. Therefore, everyone needs periodic rest, especially those over 50, due to the accumulation of connective tissue micro-damage.
Every couple of months:
Take a dedicated rest period. This could be a full week off, several very light days, or two weeks of minimal activity.
This break allows your body to reset, heal the accumulated damage, and dissipate deep fatigue.
Without this reset, fatigue and tissue stress simply build until they cause problems.
This cycle—adjusting a variable, building up slowly, and incorporating mandatory rest every few months—is your proven strategy to overcome fatigue and train sustainably.
Conclusion
Recognizing the signs of overtraining—excessive fatigue, strength plateaus, persistent joint pain, disrupted sleep, and loss of motivation—is the first step toward sustainable fitness. By listening to your body and implementing a structured recovery plan, you can reset, rebuild, and return stronger. At Speediance, we believe in training smarter, not just harder. Embrace the cycle of gradual progression, strategic adjustments, and periodic rest to achieve your fitness goals without compromising your health. Your body is your guide—trust its signals, and let it lead you to long-term success.
