Once you have purchased a program and entered all your personal details, you will be redirected to the members area and emailed instructions on how to download the app. From there you will have your program ready to access.

Yes. You have the option of a 4 weekly based program or annual. You will receive new training programs, masterclasses and content each month in addition to monthly coaching calls and support from the Onyx Performance team.  You are not locked into a contract and can cancel anytime.

Yes of course. We have clients all over the world.

No, each month offers something new. This includes increasing the weights you lift, introducing new exercise variations, and adjusting your diet as your body evolves. It’s important to continually challenge your body to ensure progress.

No. Please DO NOT purchase if you are seeking dietary advice for non-meat eaters. Go to find a specialist in that area. 

No, you’ve tried diet culture.

You’ve tried calorie-counting apps, “balance” in life, bootcamps, quick fixes and restrictive nonsense that only works short term.

ONYX isn’t that.

We don’t do diets. We don’t do counting grains of rice into plastic pots. We don’t do punishment.

We rewire your identity, build your body with progressive strength training, and lock in high-performance habits that actually last.

If you’ve tried everything - good. That means you already know what doesn’t work. Now it’s time for what does.

Neither.

We don’t spoon-feed our clients, and we don’t cheerlead our clients. If the only way you can stay motivated is if someone is chasing you, then ONYX is not for you.

We don’t tailor what we do to your “preferences.” That’s exactly what got you stuck in the first place, you trying to shoehorn your “preferences.” into a plan and because you are intelligent and pull the wool over the eyes of most people, you got away with it - that does not happen here. 

We teach you to achieve emotional freedom around food so you build your diet around what’s optimal for your goals not your cravings or compulsions.

So yes, it’s our way or the highway. Our system works for time-poor, high-achieving women over 35. Not for protein pancake addicts or boutique cardio junkies.

But you’re not left alone. 

You’ll have:

• Weekly group coaching calls (submit your questions in advance, we coach you directly)
• A community of high-achievers who raise your standards and have your back.

If you’re too busy to take care of the one body you’ve got… then when, exactly, do you plan to make time?

You don’t need more time. You need better systems, decisions, discipline and standards.

ONYX was built for busy entrepreneurs, execs, and professionals who run households, teams, and businesses. 

If you can’t make ONYX fit, you won’t make anything fit.

Delaying is just another form of self-sabotage.

Absolutely not.

Counting calories is the hamster wheel you’ve been stuck on for years. We’re not here to feed your obsession. It’s boring and completely unnecessary. 

Instead, we use a baseline nutrition framework: 30–50g protein, 3 meals a day, real food, repeat. 

This works for fat loss, performance, hormones and cravings and frees you from the diet app prison.

No. ONYX is for high-achieving women. 

Period.

Whether you’re an entrepreneur, founder, exec, lawyer, doctor or professional, what matters is that you’re ambitious, driven and done with mediocrity.

The only non-negotiable? You must have standards. 

That’s old thinking. 

There is no wagon. It’s a unicorn and hens teeth idea you made up about how you will only do something when its “perfect”. 

That’s a low standard and shaming yourself for not being a “good girl” is also fruitless and boring. 

With ONYX, you don’t need to start over every Monday. You learn to navigate real life - stress, business travel, social events - without sabotage. 

We teach you how to reset, reframe and keep momentum without spiraling.

Falling off isn’t the problem. Staying stuck is. ONYX ensures you don’t.

Yes. In fact, ONYX was built for you.

We know your physiology is different. We know stress, perimenopause and hormones change the rules. 

We’ve built ONYX around what works for women 35+ - protein, strength, recovery and identity calibration.

No BS.  No calorie obsession. Just the elite foundations that keep you hot, lean, and magnetic for decades to come.

Then ONYX isn’t your only option.

If you want VIP, one-to-one, all-in coaching, you can apply for Private Consulting with Rachel and David. A five figure investment for a minimum 4 months of deep, bespoke work.

ONYX, at $129/month, is for women who want the proven system, the structure, the identity tools and the A-player community. 

If you need hand-holding and someone to chase you to tick boxes, you’re not ready for ONYX.

Meal plans can help for ideas but they trap you in dependency. You are not a 2 yr old who needs to be fed by mum. 

At ONYX, we teach principles first, so you can adapt anywhere: on the go, traveling, or at dinner with colleagues.

Protein pancakes…

Low fat Greek yogurt with protein powder mixed in…

Breakfast “smoothies”...

There’s nothing “bad” or “wrong” with these foods…

Except that the satiety, satiation, and nutrient density is through the floor compared to a meal designed for grown ups who don’t need to be entertained by meal times!

Appetite regulation is critical for people who have struggled with their weight for years, because they don’t just have emotional hunger, they have elevated physical hunger signals too.

Hence the success and popularity of GLP-1 inhibitors.

But what if we could regulate your appetite without drugs…?

That’s what happens when you learn to optimise your diet for the thermic effect of food, satiety, and satiation AND combine this with emotional and behavioral change. 

The NUMBER 1 reason why people struggle in weight loss:

It's all of the “fuck it!” moments!

• “It’s a bad day so I might as well write it off and start again tomorrow”
•  “You know you’re going to binge eventually so you might as well do it now”
•  “Work is simply too crazy right now, I’ll get back on track after this deadline”
•  “I’ll just feel so much better if I have a taste”
•  “I promise this is the last time”
•  “Just this once”
•  “I don’t want to justify my diet choices to my mum/friends/colleagues so I’ll just do what they’re doing”
•  “I can’t be bothered to shop/cook/train tonight, I’m too tired, I deserve a break, I’ve been working really hard”

None of these “fuck it” moments have anything to do with nutritional strategy or fitness programs.

Yes, there are definitely diets and nutrition advice which will make these “fuck it” moments even worse…

Yes, we need to make sure that your nutritional approach is smart, simple and sustainable…

 … but stop thinking that the solution to your problems is to find the dieting holy grail that will magically eliminate all of your “fuck it!” moments!

If you don’t address your subconscious programming, you will struggle forever.

Fat loss is first and foremost an emotional problem.

Which is why we give you what you want… AND what you need…

We give you the easiest, simplest, and most powerful nutrition and training approach for busy female high achievers over 35…

AND we give you deep transformation in identity, self worth, and emotional fitness, so that you can stick to the nutrition and training year round, without rebound, without FOMO, without “fuck it!” moments, and without sacrificing your business, career, or hard earned reputation.

Because they don’t tell the full story - not even close.

What matters is the emotional resilience, confidence, self-worth, and identity shifts that completely change how a woman lives. 

Before-and-afters can’t show the woman who finally stopped binge-eating, the one who got promoted because she stopped hiding, or the one who rebuilt her marriage after healing her relationship with herself.

And, truth be told, many of our clients are high-profile professionals. Women leading teams, running firms, and managing multi-million-dollar portfolios. Frankly, they don’t need to be paraded around the internet in their underwear.
