Why can two people put in a similar amount of effort and experience very different results?

For many people living with Long COVID and other post-infection conditions, this question can feel deeply personal. It may even feel like a question that haunts you, or hangs with you as you go about your day. 

You may be doing everything you can think of to support your recovery. You may be resting, pacing, eating well, trying different therapies, following medical advice, and carefully managing your energy. Yet - at best - progress can still feel slow, unpredictable, or inconsistent.

At the same time, someone else may appear to improve more quickly or tolerate more activity with fewer consequences.

This can be frustrating and confusing.

One reason for this difference is that effort is only part of the equation.

We often assume that if two people do the same thing, they should experience similar results. Yet we see every day that this isn't how human systems work.

The same exercise session can leave one person feeling energized and another needing days to recover. The same stressful event can feel manageable for one person and overwhelming for another. The same treatment, strategy, or recovery plan can produce very different outcomes.

This happens because our bodies are not machines operating from a single input. They are complex systems made up of many interconnected parts that constantly communicate and influence one another.

Everything we see, hear, feel, think, eat, experience, and do is processed through the brain and nervous system. Based on that information, the body responds, adapts, protects, recovers, or conserves energy.

The quality of those responses depends on how well the underlying systems function and the conditions within which those systems operate.

For people with Long COVID and post-infection conditions, many of these systems can be affected and not work as well as they could. Research has highlighted potential contributors, including nervous system dysregulation, immune dysfunction, inflammation, metabolic changes, altered stress responses, microbiome disruptions, and changes in how the body produces and uses energy.

While these factors may result in symptoms that look different from person to person, they all influence how much capacity is available on any given day. This helps explain why recovery is rarely a straight line and why two people can respond so differently to the same actions, or the same rehabilitation protocol.

At ThriveNinety, we respect that complexity.

Rather than focusing on a single symptom, diagnosis, or quick fix, we work to strengthen and restore high-impact brain-body systems that influence how people function, recover, and adapt.

Frameworks can be helpful because they provide structure without oversimplifying complexity. They offer practical anchor points that can guide daily decisions while still respecting that every person and every recovery journey has its little tweaks that make the difference.

This led us to develop the PEDAL™ approach, a framework designed to help people take safe and gentler actions that support the systems that help determine energy, capacity, adaptability, and resilience.

The principle is simple: When brain-body systems function better, people often function better.

Many of these systems are not fixed, but interact with other systems as part of a dynamic and interconnected whole. While we cannot control every factor that influences recovery, we can influence the conditions our systems experience each day. Those conditions affect how well our systems are primed and prepared to function, communicate, recover, and adapt over time.

PEDAL™ focuses on five areas that influence multiple systems throughout the body.

Pacing

Pacing helps us manage available capacity.

Every day, demands are placed on the body and brain. These demands can be physical, cognitive, emotional, social, sensory, or environmental.

Learning how to balance demands with available energy and mental and cognitive bandwidth can help reduce unnecessary setbacks and create conditions that better support recovery.

Exercise

Exercise offers an opportunity to stimulate, and accelerate, the body’s ability to adapt. This adaptation helps nudge body systems into being more flexible and resilient again.

Importantly, for people with Long COVID, this does not necessarily mean doing more. It does mean including specific exercises that support the body - and the body systems - to work more effectively, without overtaxing. In practical terms, this means doing exercises that support the nervous system,  improve movement control, and more. To help deploy these for the greatest positive impact at each stage of recovery, it also means dialing in the quantity and level of intensity and identifying the exercises that each person’s system responds to the most. The goal is to create conditions for positive adaptation for the system while respecting the body's available capacity.

Diet

Diet and nutrition helps create conditions that allow cells, tissues, and systems to do their jobs more effectively. Every system depends on access to energy, nutrients, hydration, and the raw materials required to function. Also, there are well documented links between our gut, brain and nervous system. Eating foods that support the gut is a wonderful way to positively impact other systems in the body and help reduce symptoms.  

What we eat matters. So do factors such as meal timing, the variety of foods eaten, and creating eating patterns that support the body's needs. Knowledge is power in this space - the more someone knows, the more they can make informed decisions that go beyond what people think of as "healthy eating” to experiencing delicious foods and simple eating habits that support the body more effectively. 

Aligning the Nervous System

The nervous system influences nearly everything we do. There is constant two way communication between our body and brain via the nervous system. Much of this happens automatically, like the communication between our organs and brain and back to our organs that can impact things like organ function and heart rate. 

It affects how we process information, respond to stress, coordinate movement, regulate energy, recover from activity, and allocate resources throughout the body.

When the nervous system is not functioning well or is not getting the right signals it can have negative implications for the rest of the body. When nervous system function improves, many other systems benefit as well. Because the nervous system influences so many processes throughout the body, it also plays a major role in creating the internal conditions under which recovery occurs. For example, if you can spend more time out of your nervous system's “fight or flight” response and more time in “rest and repair” mode, your body has more opportunity to heal. It is also less likely to send “distress” signals that can show up as Long COVID symptoms.  

Loosening Tension

Tension is often part of the body's protective response. When someone gets an injury the muscles around that spot on their body may tense up to compensate for the weakness and protect the area. The same is true when the nervous system is in flight-or-flight - people hold tension throughout their body,  

Mobility work, fascia-focused approaches, stretching, relaxation practices, and other strategies can help improve movement quality, comfort, circulation, and overall system function. It also sends signals of safety to the nervous system to help nudge it out of fight-or-flight and into “rest and repair” mode. Opening and loosening parts of the body in a deliberate way can also help other movements through the day take less effort, which can be very valuable when energy levels are low.  

Each of these PEDAL elements has value on its own to help the body function better and support symptom management and functional improvement. The real impact comes from how they work together. When they are used in combination the benefits accumulate and complement each other, this accelerates the recovery process and helps people develop a strong foundation for further improvement.   

Better pacing can support recovery. Better recovery can improve tolerance for movement. Movement can influence nervous system function. Nutrition can support adaptation and reduce inflammation. Loosening tension can reduce physical and neurological stress that may interfere with how systems communicate.

Together, these areas help create conditions that support energy, capacity, adaptability, and resilience. 

Symptom management and recovery are rarely about finding a single missing piece or chasing down every symptom on its own.

More often, it is about consistently creating conditions that allow multiple systems to function a little better. Over time, those small improvements can accumulate, helping the body do what it is designed to do: adapt, recover, and move forward.

This lets people be more confident that when they put energy into something they will feel the benefit. And over time, these elements will take less energy and effort to do, as they help build back better body function.

Warmly,
