What does your weight actually tell you?

BMI is quick and free, but it has one major limitation:

It can't tell the difference between muscle and body fat.

A recent study *following more than 4,200 adults for around 15 years found that higher body fat percentage was significantly associated with both all-cause and heart-disease mortality.

Interestingly, BMI and body-fat percentage agreed on whether people fell into the study's healthy/unhealthy categories only about 60% of the time.

That's why body composition matters.

Two people can weigh exactly the same but have very different amounts of muscle, body fat and visceral fat. And if you're training, you can lose fat and gain muscle without seeing much change on the scales.

I've delivered over 40,000 body composition scans across the North Island over the past 13 years, and I see this all the time.

The maths is simple: gain 1kg of muscle and lose 1kg of fat, and the scales haven't moved at all. Yet your body composition has changed significantly.

An InBody 570 scan looks beyond your weight, measuring things like:

Skeletal Muscle Mass
Body Fat Percentage
Visceral Fat Level
Lean Mass vs Fat Mass
Segmental Muscle and Fat Distribution - see in black and white exactly where you're gaining or losing!

And importantly, we can track those changes over time, which keeps you on track and accountable.

Stop obsessing over the bathroom scales. Your weight is just a number; what that weight is made of is far more useful.

An InBody 570 Body Composition Scan using Hawke's Bay's only medical-grade BIA analyser: is just $30.

This is something I’m incredibly proud to be part of.

As the Hawke’s Bay Special Olympics Powerlifting Coach, I have the privilege of working with some pretty amazing athletes, and I’m particularly excited because Powerlifting is a new Special Olympics sport for our region (making a return after many years), alongside the other fantastic sports already well established here.

On Wednesday 23 September, I’ll be running the Powerlifting demonstration at the Regional "Have a Go Day". To be confirmed, but likely before lunch. Although... I’ll mostly be doing the talking… the athletes will be doing the actual heavy lifting!

The best part is seeing the athletes getting stronger, growing in confidence, enjoying themselves, and finding something they’re good at and can really excel in. Honestly, you just can’t beat the smile when they nail a lift they weren’t sure they could do! 100% in the feels! ❤️💪

Just down at Bay City Gym Napier today, completing the final InBody scans for their “Feel Great in 28” Challenge!

One of the things I really enjoy about working alongside other gyms, facilities and trainers is getting to connect with like-minded people who are just as passionate about helping others achieve their goals.

It also means I get to take what I do beyond my own studio, work with more people, and help them get a clear picture of the progress they’ve made.

There’s nothing quite like those final scans after four weeks of hard work; now it’s time to see what everyone has achieved!

Good luck to everyone finishing the challenge!

Proud is an understatement.

Daniel absolutely smashed his powerlifting competition today.

Living with dyspraxia and a developmental learning disability has never stopped him turning up, putting in the work, and giving everything he's got.

WCPA Mid-year Classic at 316 Fitness, Paraparaumu.

Squat: 145kg (+15kg PB)
Bench: 65kg (+10Kg PB)
Deadlift: 190kg (+15kg PB)

Watching his confidence and strength grow over the past while has been one of the most rewarding parts of volunteering with him. Days like today are proof that hard work, determination and the right attitude can achieve incredible things.

A huge thank you to Brendan and Aimee for their support.

Bring on the next one! 💪

Today was the first time I've donated plasma.

Up until now, if you lived in Hawke's Bay, the closest place to donate was Palmerston North. So this morning I headed over to the new centre in Toi Toi, Hastings.

Because of my size, they took the maximum donation of 880ml of plasma. The whole process took about an hour and a half, so I caught up on a few episodes of Prime while being looked after with juice, cheese and crackers!

A pretty easy way to help others and definitely something I'll do again. If you've ever thought about donating, now that it's available here in Hawke's Bay, I'd encourage you to give it a go. I was surprised that they're able to keep it for 2 years.
