This One Number Reveals If You’re Aging Too Fast

Gday legend!

First off—Happy Mother’s Day to all the incredible women who brought us into the world. One of the toughest parts about trying to make an impact globally is being on the other side of the world from your family. But my mum’s always been incredibly supportive of my mission. During our chat on Sunday she was actually visiting her mum—my Nunna, who is getting close to 90 now, and up until recently, she’s been super active. Whilst in todays age, we are living longer, there are a number of lifestyle choices we are making that are affecting the quality of that life… and it can start even in our 20s. If you want to ensure you are making the right decisions now… read on…

🧠 Why Most People Are Chasing the Wrong Metric

We’ve made huge progress in helping people live longer. But if you look around, most people start losing their edge decades before they lose their health.

That’s the gap between lifespan and healthspan. Living to 85 doesn’t mean much if you’re foggy, inflamed, and rundown for the last 20. The shift often starts in your 30s:

• Afternoon brain fog

• Sluggish mornings, even after sleep

• "Wired but tired" evenings

• Plateaued workouts and slow recovery

• HRV trending down, RHR creeping up

These aren’t just signs of aging. They’re signals your recovery systems are falling behind. Most people ignore them—until it’s too late. But if you’re tracking key trends like sleep quality, stress, and cardiovascular load, you can catch the decline early—and reverse course. This is where the game shifts from reactive health… to proactive healthspan.

🔧 How to Extend Your Healthspan (and Lifespan)

Here are 3 research-backed levers I rely on pretty much every day.

1. Train Consistently—But Cycle Recovery
Overtraining = poor HRV, high cortisol, burnout. Mix in Zone 2, active recovery, and deload weeks. You will notice in my planning, I do not ‘send it every day’ I mix in a variety of intensities, hence why I lay out my plan on Sunday night.

2. Prioritize Deep & REM Sleep
It’s not just about total hours. Deep + REM impact memory, hormone balance, and tissue repair. As I have touched on before, I focus on my restorative sleep and apply my fiction reading instead of screens. I then refer to my data every day to check my trends.

3. Track HRV, RHR & Strain Trends
Speaking of trends, this is a good one to remember. If your HRV drops and RHR rises—you’re under more stress than you realize. That can be any stress eg. work, home etc. and they have an impact on your output and recovery. So refer to these trends when deciding a lot of you training modalities. I found my recovery tanked after flights. Now, I schedule low-intensity days post-travel—and I bounce back faster.

🎯 So… Is the WHOOP 5.0 Really Worth It?

Up until now, I used WHOOP to monitor the essentials like a lot of us have:
-Restorative sleep
-HRV
-Daily strain & recovery

Those tools have helped me train smarter, recover faster, and avoid burnout.
But WHOOP just introduced a new feature that takes things to another level—and I genuinely believe it’s going to motivate more people to make better daily choices.

It’s called WHOOP Age. A real-time metric that tracks your biological age and shows whether your lifestyle is speeding up or slowing down the aging process. That’s the game-changer. You now have a clear end goal—a number you can see, influence, and control. It makes healthspan real.

One of the biggest challenges I’ve had in this space is helping people care about their future health before something breaks. Now, with WHOOP Age, you can see it in real time. Because let’s be honest—no one wants to find out they’re aging twice as fast as they should be, or that their biological age is 5 years older than their actual one. But if you saw that on your wrist? You’d change something—fast.

Quick Notes

🎥 We were in a TVC with Ronaldo: Speaking of the WHOOP 5.0 launch, I was asked to be one of the athletes in the piece… the lesson.. be consistent and keep getting the reps in.

🧑🏻‍💻 I’ll be showing more on how I use WHOOP 5.0 along with other equipment to support my training and healthspan in an upcoming YouTube video — stay tuned!

🏃🏻‍♂️ The week of NYC hyrox is only 2 weeks away and the team and I at Centr are pumped. We will be having events and activations, more to come

Eat Good. Feel Good.
