Still buzzing from NZ Champs 2026 ❤️‍🔥

So proud of every 312 athlete who stepped onto that competition floor and did hard things.

Extra special seeing Stacey, Barnsie and Vili take on the big stage for the first time — putting themselves out there, backing themselves and getting it done. 💪

And huge love to Coaches Tish and Lucas for walking the talk. They spend so much time pushing, encouraging and supporting our members, so it was pretty cool seeing them out there competing and doing the hard stuff too. 🫶

Then there’s everyone behind the athletes — our coaches, support crew, family and friends who showed up across the weekend, cheered loudly and made sure our people knew they weren’t doing it alone.

Big shoutout to NZ Champs for putting on such a professional, well-run weekend and giving athletes an awesome stage to compete on.

Very proud of our athletes. Even more proud of the community around them. 💜

What a weekend, 312.

Happy end of Tongan Language Week 🇹🇴❤️

Today’s WOD was inspired by Mark Latu, Andi’s old coach from the CrossFit 275 days, who’s now doing work around introducing CrossFit in Tonga 🇹🇴

Mark reckons Tongans don’t like gymnastics… so naturally, barbell only 😂
He also said anything over 20 reps and Tongans are apparently prone to not finishing — so we kept everything at 20 😭

Andi changed the workout a little… and somehow we ended up with 6 rounds.

Oua Pelu — Don’t Fold 🇹🇴

Mālō ‘aupito to everyone who came through this morning ❤️

Such a good morning at 312 today 🌈🔥

We had some of the Rainbow Games crew join us for a little taste of the Functional Fitness event coming up on 31 October.

Today’s WOD was a mash-up of Workout 1 Pink Pony Club and Workout 3 Bad Romance — with a few extra spicy bits thrown in for good measure 😂

Safe to say it was a hot one… but the good news is, today’s version was actually harder than what you’ll see at Rainbow Games 😮‍💨

Huge thanks to everyone who came along, got stuck in and made our guests feel welcome. The vibes were unreal from start to finish — including the Zumba cool-down to finish things off 💃😂

This is what we love about 312 — good people, good energy and a little bit of suffering together. 💜🌈

If your gym friends aren’t your biggest supporters and your biggest bullies at the same time… are they even your gym friends? 😂💀

It’s all love at 312. 💜
Mostly.

Find your people who hype you up, call you out, make you go heavier and somehow convince you to come back and do it all again tomorrow. 😂

Kia kaha, shut the waha. 🤝💜

“Everyone point at Kesa on 3…”

1… 2… 3… 👀👉😂

Meanwhile Kesa: completely clueless.

A huge congratulations to our July Member of the Month — Kesa! 🏆💜

After starting the year dealing with an injury, Kesa has come back STRONG. She’s been showing up, lifting some seriously heavy weights, pushing herself outside her comfort zone, and constantly putting work into the things that don’t come easily — especially those gymnastics 👀😂

What we love most is the grit behind it all. She doesn’t shy away from her weaknesses. She works on them.

Heavy lifts. Hard work. No shortcuts. 💪

Congratulations Kesa! Very well deserved. Thanks for being such an awesome part of the 312 whānau. 💜
