Long COVID / ME / Chronic Fatigue / EBV is one of the most frustrating conditions out there—it can feel like you’re doing everything right, yet you’re still battling fatigue, brain fog, and a body that just won’t cooperate. I get it. As someone with a PhD specializing in exercise for chronic illness and personal experience navigating post-viral fatigue, I’ve seen firsthand how the advice to “just rest” can actually make things worse in the long run.

Here’s the thing: movement, done correctly, is essential for rebuilding your energy reserves. Yes, pacing is important, but avoiding exercise entirely can lead to deconditioning, making daily activities feel even harder. And while traditional strength training might not be the first thing you jump into, there are ways to move that help your recovery rather than set you back.

Understanding Long COVID / ME / Chronic Fatigue / EBV at a Cellular Level

To make sense of why exercise and other strategies help, let’s look at what’s happening inside the body:

• Mitochondrial Dysfunction & ATP Production

Your mitochondria—the powerhouse of your cells—are struggling to produce energy efficiently. This leads to extreme fatigue because your body isn’t making enough ATP (your energy currency). Exercise, when introduced gradually, can help stimulate mitochondrial function over time.

• Chronic Inflammation & Immune Dysregulation

Many people with Long COVID have persistent inflammation and an immune system that’s either overactive or misfiring. Supporting the body with the right nutrients (zinc, omega-3s, and vitamin D, for example) and stress management techniques like breathwork can help regulate immune function.

• Autonomic Nervous System Dysfunction (POTS & Dysautonomia)

If you feel lightheaded when standing or your heart races unpredictably, your autonomic nervous system might not be working correctly. Breathwork, hydration, and gradual exposure to movement can help stabilize your nervous system over time.

How to Exercise Without Making Things Worse

The mainstream advice I see about exercise and Long COVID / ME / Chronic Fatigue / EBV often leans too far into the “don’t do anything” camp. While I fully acknowledge post-exertional malaise (PEM) is real, I also know that not moving at all leads to a lower overall capacity to handle daily life. The key is smart, intentional movement—not just pushing through exhaustion.

Here’s what I recommend based on both personal and professional experience:

1. Start with Breathwork & Nervous System Regulation
