S4E06. Experiment to Excel: How High Performers Optimise Their Habits
Stay at the Top
What Is A/B Testing for Health?
Jess defines A/B testing and explains applying it from business to personal health to avoid guessing.
In this episode of Stay at the Top, I introduce a powerful mindset shift that high performers know well in business but rarely apply to their health: A/B testing.
In marketing and business, A/B testing is second nature. You compare two strategies side by side, measure the results, and double down on what works. But when it comes to health and performance, most people take a “set and forget” approach. They hear a new strategy, protocol, or trend, adopt it, and stick with it without ever testing whether it is truly working for them in both the short and long term.
I share how bringing an experimental mindset to your health can help you stop guessing and start leading yourself like the high performer you are. From nutrition and training to sleep and recovery, this episode will show you how to build your own personal playbook instead of relying on one-size-fits-all advice.
In this episode, I cover:
- Why high performers need to apply A/B testing principles to health, not just business
- The risks of blindly following trends without testing whether they work for you
- A client case study on fasting: why short-term gains sometimes hide long-term costs
- How objective measures like DEXA scans and wearables can give you visibility under the hood
- Practical examples of what to test, from pre-training fuelling to sleep routines and hydration
- How to combine subjective data (energy, mood, focus) with objective data (body composition, HRV, recovery scores)
Key Quotes:
“If you are not testing and measuring your health strategies, you are guessing.”
“What works in the short term does not always translate to long-term success.”
“High performance starts with personalisation.”
“This is how you stop guessing and start leading yourself like the high performer you are.”
