Know Your Physio Case Study: Colin B.

How data-driven health coaching helped Colin lift his sleep score 35 percent, deepen his recovery, and reverse burnout with breathwork and better sleep timing.

Aug 15, 2026 · 5 min read

“I feel so much better.”

Colin did not have a motivation problem. He had the opposite. A driven 33-year-old running hard on a nervous system that had stopped recovering, he described himself, in his own words, as classic burnout. He leaned on stimulants to push through the day and crashed without them. The drive that made him successful was quietly running his body into the ground, and no amount of effort alone was turning it around.

What changed was not a harder routine. It was data-driven health coaching: recurring check-in calls where Andrés sat down with Colin’s wearable data and read it alongside him, turning an invisible, dysregulated nervous system into numbers they could actually move. Over a span of weeks, the shift showed up first in how Colin felt, then in how he slept, and then in the recovery markers underneath it all.

Day 1: Baseline Assessment

The Challenge

Classic burnout. A high-stress, time-constrained professional describing his own nervous system as dysregulated, leaning on stimulants to push through the day and crashing without them. The drive was never the problem. The recovery underneath it was.

"I'm classic burnout."

For a long time the problem was not knowledge, it was feedback. Colin was doing plenty, but without an objective read on his own physiology he could not tell what was helping and what was quietly draining him. The turn came when the coaching stopped being about pushing harder and started being about reading the data. When the numbers began to move, Colin felt it before he saw it, and he said so plainly:

“My workouts are feeling better. I’m feeling like stronger immediately.”

A Self-Reported Leap

Colin walked into his next session leading with the number himself. The sleep score climbed roughly 35 percent between sessions , the kind of momentum that shows up in how a person feels long before it shows up anywhere else.

The clearest signal came from his sleep. Between two coaching sessions, Colin’s sleep score climbed by roughly 35 percent, a jump he was so aware of that he led with it the moment the next call began. It was the kind of momentum that is hard to fake and harder to ignore.

Just as telling was how it arrived. The gain did not come from a punishing protocol. It came from a handful of small, repeatable habits and a nervous system that was finally allowed to recover. For someone who had been relying on stimulants just to function, sleeping well and waking easily was not a minor win. It was the foundation everything else would be built on.

Sleep Quality & Recovery

As the nervous system settled, the markers underneath began to move in the right direction.

Deep Sleep Percentage

At 28 percent, his deep sleep already sits at the strong end of the range, the restorative stage where the body does its physical repair. With resting heart rate trending down from a 72 baseline toward a record low, the recovery system is doing exactly what a settled nervous system should.

Underneath the sleep score, the recovery markers told the same story. Colin’s deep sleep, the restorative stage where the body does its physical repair, came in at a strong 28 percent, which his coach flagged as genuinely good. His resting heart rate, which started at an elevated 72 beats per minute, began trending steadily downward toward a record low for him, a classic sign of a nervous system shifting out of fight-or-flight and back into recovery.

Andrés noted that Colin was becoming far more resilient in the face of stress, holding those gains even through a demanding week. The man who had been running on empty was now, by the data, building a reserve. Waking up, once a daily battle, had become a non-event:

“I’m getting up earlier, much easier, no issue at all.”

What Moved The Needle

Breathwork in bed, an earlier last meal, and a pre-bed shower. Unglamorous, repeatable, and entirely his own. When Colin was asked what was working, he answered without hesitation: "Breathing, eating before bed, and shower. No doubt, shower. I might fall asleep immediately."

The habits behind the change were almost boring, and that was the point. Colin practiced breathwork in bed, moved his last meal earlier in the evening, and added a pre-sleep shower to wind down. None of it was extreme. All of it was repeatable. When asked what was actually working, his answer was immediate and specific: “Breathing, eating before bed, and shower. No doubt, shower. I might fall asleep immediately.” Small inputs, applied consistently, were exactly what his nervous system rewarded.

Foundations of Success

A nervous-system-first approach built on data, breathwork, and consistent habits.

Wearable Data

Daily HRV, resting heart rate, deep sleep, and sleep-score tracking turned an invisible nervous system into numbers Colin and his coach could read together, week over week.

Professional Oversight

Recurring check-in calls where Andres reviewed the dashboard alongside Colin and translated the data into specific next actions, dosed to what a recovering nervous system could actually absorb.

Nervous-System Regulation

Breathwork in bed and a pre-sleep wind-down replaced the stimulant-fueled push-and-crash pattern, helping a dysregulated system shift back into a recovery-ready state.

Consistent Habits

An earlier last meal, a pre-bed shower, and a steady wind-down. Nothing extreme, all of it repeatable, so the foundation keeps paying off night after night.

The Strategy

"He was never asked to follow advice on faith, he could watch, week over week, exactly how his body was responding."

Colin’s story is still being written, and that is part of what makes it credible. This is not a finished before-and-after. It is a recovery in motion: a dysregulated nervous system settling, sleep deepening, resting heart rate trending down, and resilience building week by week from honest numbers rather than wishful thinking. The plan was never the hard part. Seeing it work, in his own data, is what made it stick.
