Two people, same age, very different futures — and the gap between them started decades earlier, in something neither of them had ever measured.

A Cleveland Clinic study followed more than 122,000 people and found this one number predicted who lived, and who didn't, more strongly than smoking, diabetes, or blood pressure. It's called VO2 max, and unlike your age or your genes, it's trainable at any stage of life.

Not sure what to do with your number once you have it? We're happy to point you toward the right next step — your own coach, your gym's programme, or just where to focus first.

Blood pressure, muscle function, hydration. It all comes down to 3 minerals:
Potassium
Magnesium
Sodium

General advice says cut sodium. Training hard says replace it.
Potassium and magnesium are easy to top up through food (magnesium might need supplementation). Sodium is the one that actually needs individual testing, since sweat losses vary so much person to person. Full breakdown is in our current newsletter.

Turns out "she's salty" has a scientific explanation. 🤯

Cramping. Bloating. Heavy legs half way through a longer session. Most people write it off as bad sleep or overtraining.

The usual culprit is sodium -- and how much you lose has nothing to do with how much you sweat! 💦
Tony, our founder, isn't a heavy sweater at all, but his own sodium sweat test came back high, which he was surprised about.
And so are others:
"My number explains the cramping and heavy legs. I'd been guessing, and I was only refuelling about a third of what my number says I should." - Dale W., who took the test with us.

Same test. Three completely different numbers.

Sweating heavily doesn't mean you're losing a lot of sodium -- three people, three surprises.

Cramping, heavy legs, headaches, fatigue: most people don't realize their sweat sodium number is the reason.

As Dale said after he got his results: "My number explains the cramping and heavy legs. I'd been guessing, and I was only refuelling about a third of what I should have been."

If you're like Luise, you've tried the diets, the training blocks, the rhythms that were supposed to fix everything.

Some helped. None gave the full picture.

Luise, our Co-Founder, built her side of Tristar around exactly that gap -- metabolic health, community well-being, and breathwork, grounded in your actual data instead of whatever's trending this month.

If any of this resonates, follow us. We share our own experiences and of course the science behind better performance and overall longevity.

Also, have a chat with us! We are almost normal people. 🤣

Most people never think about how they breathe.

It turns out to be one of the most trainable things about your health -- shaping your sleep, your stress response, and your metabolism.

Luise is an Oxygen Advantage certified Breathwork Instructor. She leads our breathwork and metabolic health work at Tristar, built around your actual physiology, not another trend.

Start with a single session, or go deeper with one of our 6-week programmes: Functional Breathwork or Performance Breathwork, depending on what you're after.
