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. 💜

Matching songs to our members: AM class edition 🎶😂

Some were obvious. Some were questionable. Some were way too accurate.

Part 1… because the whole crew has far too many characters for one reel 👀

Part 2 of investigating what coaches actually do during a running WOD 😂

Today’s workout had a 3 km run buy-in, and my coaches absolutely understood the assignment.

The athletes ran. The coaches danced, napped, played with the dog, and disappeared to the toilet.

Elite support from a safe distance 💃🏽🐶😴
