Tainui Kaihau
Hi guys, I'm Tainui. I’m a plumber by trade and a business owner who believes discipline beats motivation every time.
I run my own plumbing business, work long, physical days on the tools, and train consistently because I take my health seriously — not for aesthetics, but for capacity. I want to be strong enough to handle long days, build a solid business, and still show up properly at home.
When I was 17, I was diagnosed with leukemia. That experience changed my outlook early. Health stopped being something I assumed I’d always have and became something I actively protect. Since then, I’ve built my lifestyle around strength, structure, and consistency: training hard, eating well, recovering properly, managing stress, and staying fit.
I value optimal health, hard work, and building a life you’re proud of. My relationships matter. My business matters. My performance matters. And none of that works properly if your health suffers.
I’m not into quick fixes or shortcuts. I focus on foundations: whole foods, proper training, good sleep, and simple supplementation that supports what I’m already doing.
That’s why I use Switch. It fits into my day-to-day without overcomplicating anything. It supports the standard I hold myself to — in business, in training, and in life.
