Don’t Be a Hero—Training Sick Can Set You Back

We’ve all been there. You wake up feeling a bit off—blocked nose, sore throat, low energy—and the question hits:
“Should I still train today… or am I just being soft?”

Truth is, it depends. Sometimes moving your body helps. Other times, it’s the last thing you need. So let’s cut through the overthinking and lay it out simply

The “above the neck” rule

If your symptoms are mild and above the neck—think runny nose, sneezing, or a bit of a sore throat—light training is usually fine. In fact, gentle movement can even help you feel better. A walk, some mobility work, or a very light session can help clear your head without digging a deeper hole. But this isn’t the time to smash a PB or go chasing sweat for the sake of it. Keep it low intensity, short, and listen to your body as you go

When to rest (no negotiation)

If symptoms move below the neck—like a chesty cough, tight lungs, fever, body aches, or gut issues—it’s time to rest. Pushing through won’t help you “sweat it out”; it just increases stress, delays recovery, and can make you feel worse. The same goes for dizziness, nausea, or fatigue that wipes you out—those aren’t signs to train, they’re signals to pause

Getting back into training (without making things worse)

If you're recovering from something contagious—like the flu or COVID—do everyone a favour and stay home. Training too soon puts your own recovery at risk and exposes others unnecessarily. Give your body the rest it needs, and come back when you're truly ready

Once you’re feeling better, ease back in gradually. Start at 50% of your usual intensity or volume and pay attention to how your body responds. If a session feels harder than it should or wipes you out afterwards, that’s your body telling you it's not quite ready yet. Respect the process. There’s no bonus points for rushing back too soon

What to eat while you’re down

You don’t need a perfect meal plan while sick—but eating something matters. Your metabolism speeds up when your body’s fighting off illness, so skipping meals or undereating slows things down.

Stick to warm, simple, easy-to-digest foods:

• Broth or soup for hydration and electrolytes

• Bananas or toast if your stomach’s sensitive

• Garlic, ginger, and honey for immune support

• Tea for warmth and congestion relief

Eat what feels manageable. The goal is fuel, not perfection

The bottom line

Training while sick isn’t a sign of dedication—it’s often a fast track to burnout. In many cases, rest is the most productive choice you can make. If your symptoms are mild and above the neck (like a light cold), gentle movement might be okay. But if it’s anything deeper—like fatigue, fever, or body aches—rest is non-negotiable. When you’re ready to return, ease back in, support your recovery with proper nutrition, and give your body time. There’s no reward for pushing through illness—but there is real progress in knowing when to hit pause
