Do Wellness Challenges Work? The Science Behind Employee Engagement
Wellness challenges are everywhere – but do wellness challenges work, or are they just a fun distraction? The research gives a clear answer: challenges that are built on a few proven behavior-change principles do increase activity and engagement. Challenges that ignore them tend to fade quickly. Here is what the science says and how to apply it.

The Short Answer
Large workplace wellness programs have mixed evidence when it comes to medical costs (we cover that honestly in how to measure wellness ROI). But the evidence for well-designed physical activity challenges is much stronger: tracking, goals and social features consistently help people move more. The key is design.
5 Science-Backed Ingredients of a Wellness Challenge That Works
1. Self-Monitoring With a Tracker
Seeing your own numbers changes behavior. A review in JAMA found that pedometer users increased their physical activity by about 27%, or roughly 2,000 steps a day. A more recent umbrella review in The Lancet Digital Health found that activity trackers increase walking by about 1,800 steps a day. Read more about the benefits of a fitness tracker.
2. Clear Goals
The same JAMA review found that having a step goal was one of the most important factors behind the increase in activity. Specific, achievable targets – a daily step goal or a goal reached on a set number of days – turn good intentions into action.
3. Social Connection and Friendly Competition
People move more together. In the STEP UP trial by Penn Medicine, about 600 Deloitte employees used wearables with different game designs. Compared with the control group, the competition group walked about 920 more steps a day, the support group 689 and the collaboration group 637. Three months after the game ended, the competition group was still walking about 569 more steps a day than the control group. Read more in the challenge effect.
4. Autonomy and Choice
People stick with exercise longer when they do it because they want to, not because they have to. A systematic review based on self-determination theory found that this kind of autonomous motivation predicts long-term exercise adherence. In practice: keep challenges voluntary and offer different types so people can choose what suits them.
5. Time and Repetition
Habits need time. In a University College London study, it took 66 days on average for a new behavior to become automatic. A series of challenges across the year builds habits that a single one-month event cannot. See why an annual wellness plan beats a one-time challenge.
What About Rewards?
Rewards can boost sign-ups and give a challenge a fun finish, but they are not what keeps people moving long term – enjoyment, social connection and a sense of progress are. Use rewards to recognize effort and participation rather than to pay people to exercise. For practical ideas, see employee wellness incentives: what works and what backfires and what employees say about prizes.
How YuMuuv Puts the Science Into Practice
- Self-monitoring: activity syncs automatically from Apple Health, Health Connect, Garmin, Fitbit, Polar and other devices, and everyone sees their progress daily.
- Clear goals: total, consistency and collective goals – see YuMuuv challenge types explained.
- Social connection: teams, leaderboards and a challenge chat for friendly competition and support.
- Choice: steps, distance, cycling, running, sleep, mindfulness, yoga, custom challenges and more – see the complete list.
- Repetition: run challenges back to back across the year, using templates such as the 2026 wellness challenge calendar.

Frequently Asked Questions
1. Do wellness challenges actually work?
Yes, when they combine tracking, clear goals and social features. Trials show meaningful increases in daily steps, and well-designed competition can keep part of the effect even after the challenge ends.
2. Is competition or collaboration better?
In the STEP UP trial, competition had the largest and longest-lasting effect, but all social designs helped. A mix of team competition and shared goals reaches the most people.
3. How long should a wellness challenge last?
Four to six weeks per challenge works well, repeated through the year to turn short-term changes into habits.
