Your Wrist Knows Best!
How Wearable Tech is Revolutionizing Personalized Fitness
We all know regular physical activity is vital for health, yet globally, movement levels remain stubbornly low, contributing to chronic diseases like type 2 diabetes and cardiovascular issues. But what if we could shift our perspective, viewing activity not just as a healthy choice but as a genuinely rewarding one?
Enter the exciting intersection of wearable technology and smart incentives.
Public health innovators and researchers are increasingly exploring financial rewards, facilitated by wearable devices, as a powerful strategy to encourage physical activity. These tools offer a dynamic advantage: they track our movement in real time and can deliver tailored encouragement or rewards based on our unique daily patterns.
A compelling new study by Gregory Ang, Chuen Seng Tan, Nicole Lim, Jeremy Tan, Falk Müller-Riemenschneider, Alex R. Cook, and Cynthia Chen from Singapore's National Steps Challenge™ Season 3 (NSC3) delves into this very approach. By meticulously analysing high-resolution step data from thousands of participants, researchers aimed to answer a surprisingly underexplored question: How do individuals accumulate their steps throughout the day in response to incentives—and how can this understanding lead to more effective health interventions?
Let's explore the study's key findings and their implications for the future of wearable technology, personalised health strategies, and public policy.

Decoding Movement: When and Why We Step
The study uncovered distinct patterns in participants' daily movement:
Weekdays: Showed consistent peaks in step counts during typical commute times (7–9 AM), lunchtime (12–2 PM), and early evenings (6–8 PM).
Weekends: Exhibited a later shift with generally fewer steps overall, indicating a more relaxed daily routine.

Older Adults (60+): Surprisingly recorded higher step counts than younger age groups until 6 PM on weekdays—potentially due to greater availability of leisure time or established activity routines.
Crucially, the data revealed noticeable surges in step counts around the incentive thresholds of 5,000, 7,500, and 10,000 steps. These sharp increases strongly suggest that participants were consciously pacing or increasing their activity to reach these predefined rewards.
And here's a key insight: The researchers discovered that reaching 7,000 steps by 7 PM was strongly linked to achieving the 10,000-step goal by the end of the day. This finding presents actionable opportunities—timely prompts or reminders around early evening could significantly improve the likelihood of hitting daily targets.
Personalized Step Guidance: Hourly Benchmarks for Better Outcomes
A significant contribution of this study was the development of hourly step recommendations—a practical guide for individuals to monitor their progress and adjust their activity throughout the day. These recommendations were tailored based on demographic factors, particularly age and work routine, to reflect the diverse realities of different lifestyles.
Hourly Step Recommendations to Achieve Daily Goals (Working and Older Adults):
These benchmarks serve as both motivational targets and practical planning tools for individuals, health coaches, and digital platforms aiming to optimise movement patterns.
The Significance: Timing + Technology for Impact
What are the broader implications of this study for the effort to combat physical inactivity?
It highlights that we are only beginning to understand the potential of wearable technology and smart incentives. Instead of broad recommendations like “Walk 10,000 steps a day,” we can now consider more nuanced questions:
What time of day are you most likely to be active?
What is your current progress toward your daily goal?
How can we provide timely encouragement to help you stay on track?
This study lays the groundwork for designing timely, personalised interventions—such as push notifications reminding users to take a walk at 6:30 PM if they are falling behind. These small, strategically timed nudges, informed by behavioural science and real-world data, could lead to significant improvements in population health outcomes.
⚠️ Important Considerations
It's important to acknowledge the study's limitations:
Selection Bias: Voluntary participation in NSC3 might have resulted in a sample skewed towards more health-conscious individuals.
Lack of Control Group: The absence of a randomised control group limits the ability to establish causal relationships.
Contextual Specificity: Singapore’s unique geographic characteristics, safe walking infrastructure, and tropical climate might not be representative of other countries.
Nevertheless, the rich dataset and thoughtful analysis provide valuable insights that can be adapted to various contexts with appropriate modifications.
Final Thoughts from ResearchBunny
This study bridges a crucial gap between public health goals and individual behaviour. It shows that the “how” and “when” of movement matters just as much as the “how much”. By harnessing wearable tech, financial incentives, and behavioural insights, we can create smarter, more responsive strategies to get people moving—not just more, but better.
As we look ahead, future research should explore how real-time interventions based on these insights can further boost outcomes—and whether similar patterns hold true across cultures and lifestyles.
In the meantime, one thing is clear: with the right mix of motivation, timing, and tech, every step counts—especially the ones you take before dinner.
