The promise was flexibility. More time, less commuting and better work–life balance. And in many ways, the promise has been delivered. Gallup now reports that six-in-10 employees with remote-capable jobs prefer a hybrid work arrangement, while fewer than one-in-10 prefer to work on-site, making it clear that for many organizations hybrid work is here to stay.

But something else has happened at the same time. As organizations embraced hybrid work, many of the invisible systems that quietly supported our health, energy and performance disappeared. I see the consequences in conversations with leaders, executives and high performers every week.

The shift happened fast and the focus went on policies, technology and office redesign. What got left behind were the daily rhythms that had quietly supported health, energy and performance all along. The office, as it turns out, was doing far more heavy lifting for our health and performance than most of us realized. The focus now needs to become helping people stay healthy and perform well within it.

The invisible operating system of the office

Before hybrid work became the standard for many businesses, much of the structure that supported performance happened automatically. The commute created a transition. You left home, you arrived at work and, at the end of the day, you came home again.

Each of those moments signaled that one part of the day had ended and another had begun. Our bodies and brains thrive on that kind of consistent, predictable rhythm.

Lunch away from your desk provided a natural brain break. Walking between meetings, taking the stairs or getting up to speak to a colleague created moments of movement and connection that were built into the day without much thought.

Research shows that people working from home are less physically active and spend more time sitting than those working on-site. Movement dropped incidentally as a by-product of the environment shifting and most people simply never built a replacement.

What actually breaks down at home

When I work with leaders and high-performing teams struggling to maintain their energy and health when working from home, the breakdown almost always follows a predictable pattern. Habits and structure shift by a few degrees, and across months and years the cumulative effect is significant.

Nutrition is often the first thing to shift. Working with a senior executive recently, we realized that his working-from-home days had gradually disrupted his entire nutrition rhythm without him noticing. Breakfast became inconsistent. Some days he ate it, other days he didn’t.

Because of this, lunch was inconsistent and, as a result, his afternoons had become less productive. None of this was intentional or obvious at first, but the cumulative effect was lower energy, poorer decision-making and a greater reliance on caffeine and convenience.

Movement is often next to shift. More than half of Australians do not meet basic movement recommendations, and this was before hybrid work stripped out much of the incidental movement built into the office day. Even brief movement breaks, which I like to call exercise snacks, can meaningfully improve focus, mood and metabolic function, but unlike the office, they now require deliberate planning rather than happening more organically.

In a traditional office environment, leaving the building created a clear transition between work and recovery. At home, that transition is far less distinct.

Research has shown the boundary between work and recovery becomes blurred, and without deliberately creating that transition yourself, it becomes harder to separate work and home, hindering recovery from work-related stress.

The fix is structured flexibility and rhythm

Over the past 15 years working across elite sport, Special Forces and executive leadership teams, I’ve noticed something remarkably consistent. The leaders and teams who sustain high performance don’t rely on motivation. They create enough structure to make the right behaviors easier, and they’re clear on the handful of non-negotiables that protect their health, energy and performance.

They’re not following complicated morning routines and making health another thing on their already full to-do lists. They’ve intentionally rebuilt the structure the office once provided, while maintaining the flexibility that hybrid work offers, which includes:

• They protect a consistent start time and finish time

• They schedule movement the way they would an important meeting

• They protect time to eat lunch away from their desk

• They deliberately create pauses between periods of cognitive demand

• They finish the day with a deliberate transition that signals work is over

Working from home is not going away for many organizations, and neither are the demands placed on leaders and their teams as they navigate change and uncertainty.

The organizations that thrive won’t simply offer flexibility. They’ll recognize that hybrid work changed the operating environment and intentionally rebuild the systems that support health, leadership capacity and sustainable performance.

Staying healthy isn’t separate from performing well. It is one of the systems that makes high performance possible. The office once provided much of that structure by default. In a hybrid world, we have to be aware of this and build it intentionally.
