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.

Daily Foundation

Purest Creatine: Creatine is a daily staple for me and a long-term foundation for strength and performance. With the amount of training I do, it helps support power, endurance, and recovery by replenishing ATP. Over time, it also supports lean muscle and mental focus, making it a simple, proven supplement I rely on for both performance and longevity.

On-Site Long Working Days

Hydrate: A non-negotiable - replenishing key electrolytes to support optimal hydration. Supporting energy levels and focus through training and day-to-day life.

Training & Endurance

Amino: Supports muscle recovery, reduces fatigue, and helps preserve lean muscle during training.

WPI Protein: Fast-absorbing protein to support muscle recovery and growth. It gives my muscles the immediate fuel they need after tough sessions, helping repair tissue and maintain lean muscle mass.

Recovery

Adrenal: Supports stress management, recovery, and nervous system balance. It helps my body switch out of go-mode, wind down properly, and recover more effectively after busy days or intense training sessions.
