At Domain Fitness we aren't training for 'the gym'.

We're training for life.
This is the reasoning behind our 'Complete Training' track & approach.

It's easy to get caught up in PBs, leaderboards, and workout times.
But we take a step back and ask: why do 95% of our new members actually walk through the door?

They want to feel well and live well NOW.
They want to age well.
They want energy.
They want to feel capable.

That's what Complete Training is built for.
The movements are functional and transferable — squats, hinges, presses, carries, loaded locomotion.
Things the human body is designed to do.
Things that make real life easier.

At Domain Fitness you won't see high-skill gymnastics under fatigue.
You won't see movements that take months to learn before they're useful.
Every exercise is chosen because it works for most people, most of the time, and when modified, is still extremely effective across every fitness level.

When looking for a gym ask yourself "What is it I want to be able to do?"
We will show you the training method, deliver expert coaching and a supportive community that will get you there.

Zone 2 has had a massive moment, but a new narrative review confirms something I’ve been saying for years: Zone 2 is not the magic metabolic solution it’s been sold as.

Yes, Zone 2 (easy, steady, conversational pace) has its place. It’s enjoyable, it’s accessible, and if it gets you moving then great! But the idea that it’s the best way to build mitochondria, burn more fat, or improve metabolic health for the average person? That just doesn’t hold up in the data.

This latest review highlights how most of the Zone 2 hype came from watching elite endurance athletes—athletes who train for HOURS a day and do enormous amounts of Zone 2 work. Of course they have incredible mitochondrial and fat-oxidation capacity. But using that as the model for everyday active women? It just doesn’t translate.

The new review makes this crystal clear: Higher-intensity exercise (above Zone 2) creates bigger, more meaningful improvements in mitochondrial function and cardiometabolic health, especially when your training volume looks like a normal human’s, not a pro athlete’s (think ~5hrs a week, not 15-20+).

This is why I’ve never advocated Zone 2 for women. Yes, it’s one tool. It can absolutely live in your training week. But it’s not THE tool—and it’s certainly not the key driver of the adaptations most women actually need.

If you want stronger mitochondria, better metabolic health, and real performance gains? Use all your gears and don't be afraid to rev your engine and push into higher-intensity zones 1-2 times a week.
