I catastrophised every twinge, and learning to separate fact from story is what got me training again. Fact - my knee hurts on stairs today. Story - I am broken and this is permanent. Once I started checking which one I was reacting to, I stopped bracing for pain before it arrived, and that let me train through the recovery, wheelchair to walking stick to lifting, hiking and running, alongside losing 55 kilos.
Addressing sleep disturbance as a mental health concern has unexpectedly led to improved physical performance in my clinical observations. When sleep was restored through sleep hygiene and targeted interventions, patients commonly reported better daytime energy and steadier reaction times. The connection I discovered is that sleep serves active roles in memory consolidation, detoxification, and cellular repair that directly support motor learning and recovery. Without adequate sleep, the brain struggles to regulate mood and process new physical skills, which undermines performance. Improving sleep also sharpened cognitive focus and emotional control, which translated into more consistent results during physical tasks. This experience reinforced that treating sleep is both a psychiatric priority and a practical way to enhance physical capacity and resilience.
The mental health concern that had the clearest connection to my physical performance was chronic stress. For a while, I viewed stress and training as two separate things. I could still get myself to the gym, so I assumed everything was fine.
What I eventually noticed was that I wasn't bringing the same focus into demanding sessions. Heavy weights felt mentally harder, sleep and recovery weren't as consistent, and I was more likely to second-guess a difficult set before I even started it.
What helped was becoming more deliberate about creating separation between work and training. I'll take a short walk, step away from screens, read, or simply give myself some quiet time instead of carrying the entire workday straight into the gym. I also became much more protective of sleep and stopped treating recovery as optional.
The connection became pretty obvious: when my stress was better managed, I trained with more concentration, recovered more consistently, and made better decisions about when to push and when to back off.
That matters even more to me now that I've built my bench from 135 pounds to a 495-pound PR, with a 505-pound squat and 545-pound deadlift. At heavier loads, being physically capable isn't enough—you need to be mentally present, too.
The connection I found was between anxiety and my breathing, and it showed up in the most ordinary place — walking. I come from a kinesiology background and I teach yoga, so I always assumed I understood my own body pretty well. But I used to wake up anxious and scattered most mornings, and I never connected that to how shallow and high my breathing had gotten until I started paying attention to it during a slow morning walk.
Once I addressed the anxiety directly — 10 minutes of walking meditation early, before the day's inputs pile on — my breathing dropped lower and slower, and that changed my physical baseline more than any workout tweak had. I had more usable energy through the day, I recovered faster between hard efforts, and I stopped carrying that low-grade tension in my shoulders and jaw that I'd assumed was just posture. It turned out to be stress living in my body.
That is the part that surprised me: I'd been trying to fix a physical pattern with physical fixes for years, when the lever was my nervous system the whole time. Calm the anxiety first, and the body follows.
Honestly, this one caught me off guard. I went through a stretch a couple years back where my anxiety was running the show - constant low-level dread before meetings, trouble switching off at night, the works. I started doing daily meditation mostly to get my head straight, not because I cared about my workouts. But somewhere around month three, I noticed I was lifting heavier and recovering faster, and it took me a while to connect the dots.
The meditation practice was a lot of nervous system stuff - breathing exercises, noticing when I was bracing for something that hadn't happened yet. Turns out I'd been walking around in a low-grade fight-or-flight state for years without realizing it was a baseline, not just a bad week. My shoulders were tense before I even picked up a weight. My breathing was shallow all day, not just under stress. That's expensive, physiologically. You're burning fuel on vigilance that should be going toward recovery.
I paired the meditation with yoga a few mornings a week, actually using one of the apps we've built ourselves at Breakthrough - I'm on Stretch, running through one of our partner instructors' online classes before I even open my laptop. There's something about moving through it with an actual teacher's voice guiding you, versus just stretching on your own, that keeps me consistent in a way nothing else has.
Once I actually learned to downshift - and I mean really learned it, not just intellectually knew I should relax - my resting heart rate dropped, I started sleeping through the night instead of waking up at 3 a.m. running through tomorrow's problems, and my workouts stopped feeling like I was starting from a deficit every time.
The connection I keep coming back to is that physical performance isn't just muscles and calories, it's whatever your mind is doing in the background too. I used to think of mental health and fitness as two separate projects on two separate to-do lists. Now I think the meditation and yoga were the actual unlock, and the strength gains were just downstream of it. I tell people on my team this a lot - if your training isn't sticking, it might not be a training problem at all.
I am answering as a clinician rather than about my own training, because the pattern I watch in my office is more instructive than anything from my gym history.
The concern is panic and health anxiety. The connection is interoception, meaning the sense of what is happening inside your own body.
People with panic are frightened of a specific short list of sensations: racing heart, breathlessness, chest tightness, lightheadedness. Those are also precisely what hard effort feels like. So without ever consciously deciding to, many of them have built a ceiling into their training. They stop at the exact moment the body starts talking loudly. Ask them why and they will say they were not fit enough or they got tired. What actually happened is that a normal sensation got read as a warning.
Standard treatment for panic includes interoceptive exposure, where we deliberately produce those sensations in session, by overbreathing on purpose or running stairs, until the signals stop being interpreted as evidence of catastrophe. None of that is aimed at fitness. But the performance change is often the first thing the person notices. They tell me they finally finished the set, or ran the hill without turning around, and they are genuinely surprised, because we never trained anything.
The connection I would name is this: a lot of what presents as a physical limit is really a threshold of tolerated sensation. Treating the anxiety does not make the heart stronger. It changes what the person is willing to feel, and that alone releases capacity that was already sitting there.
One caution, and I would not want it cut. If someone's chest or breathing symptoms have not been evaluated medically, exposure is not the answer. A physician comes first, every time.

Addressing chronic stress and anxiety through hormone and peptide optimization unexpectedly became one of the biggest performance unlocks I've seen in our patients at Regenerative Revival. When cortisol stays elevated for too long, it doesn't just affect mood — it actively blocks muscle recovery, disrupts sleep architecture, and blunts strength gains no matter how hard someone trains. We had patients come in purely for mental clarity or anxiety support, and within weeks they were reporting faster recovery times and better workout output as a side effect. The connection makes sense physiologically: the nervous system and the musculoskeletal system are never actually separate systems; they're constantly talking to each other. Once we started treating the stress response directly, the physical gains followed almost automatically. It's completely reframed how we talk to patients about "performance" — sometimes the fastest path to a stronger body is calming an overactive mind first.
