How to run a workplace movement challenge employees don't hate

You announce a step challenge, build a leaderboard, maybe put up a small prize — and two weeks in, the same six people are at the top, everyone else has quietly stopped logging steps, and the Slack channel has gone silent. If this is the second or third challenge that's fizzled this way, the problem usually isn't your team's interest in moving more. It's the format.

The short answer: challenges that depend on people remembering to log something, every day, forever, lose almost everyone except the people who were already fit. The ones that hold up instead put movement on a schedule — blocked time that happens by default, the same way a meeting does — rather than asking for a daily voluntary act. Fix the format before you fix the prize.

The evidence on step challenges is mixed — and the gap is instructive

A four-week national step-count challenge run across Scottish workplaces is one of the few studies to measure this rigorously. Researchers writing in PMC/NCBI found that of 2,042 employees who initially signed up, only 246 — about 12% — had enough data to analyze by the end. Among that smaller, already-engaged group, step counts, perceived stress, and self-reported productivity all improved. But the study found no measurable change in work engagement, and the authors were candid that the design was weak, calling for better integration of research into real-world rollouts, including an actual baseline period before the challenge starts.

A separate six-week team-based challenge at a German university, described in a 2025 Frontiers in Public Health study, used a gamified app and team structure instead of individual logging. It found a short-term bump in physical activity, particularly among employees in team-leader roles — but the researchers noted that sustaining those gains past the challenge window remained the hard part, and having a leader on a team didn't meaningfully lift the other members' activity on its own.

Read together, the pattern is consistent: challenges move the needle for the subset of people who engage with them, for as long as the challenge runs. The open question both studies leave unanswered is how to get the other 88% to engage at all, and what happens in week seven.

Why most people opt out before the challenge even starts

That "who engages" question has a documented answer. A Cornell ILR / CAHRS survey of roughly 3,000 employees at a Fortune 500 company, led by researchers Brad Bell and Chris Collins, asked people to rate 14 possible barriers to joining workplace exercise and healthy-eating programs. The top barriers weren't medical or motivational — they were logistical: life demands, programs that felt too time-consuming, and a sense of being "overwhelming to engage with." Employees also cited weak social support from colleagues and supervisors as a real obstacle. Notably, remote employees reported significantly higher barriers across the board than people working from an office, and joined at correspondingly lower rates.

SHRM's own survey data on non-participants lines up with this: the most common reasons people gave for skipping a wellness offering were that they felt they could make the same changes on their own (70%), that they lacked time (56%), or that they already considered themselves healthy (53%) — not that they didn't value being active.

None of this is a motivation problem. It's a design problem: challenges that ask for a new daily decision, on top of an already full day, lose to the path of least resistance every time.

What the CDC's own framework recommends instead

The CDC's Workplace Health Resource Center draws a useful distinction between individual-level programs — challenges, apps, portals that ask each person to opt in and keep opting in — and organizational or environmental strategies that change the default for everyone at once: schedules, meeting norms, physical space. Its guidance is direct about the tradeoff: environmental and policy-level changes reach the whole workforce simultaneously and tend to hold up over time, because they don't rely on sustained individual willpower the way a challenge does. The CDC's benchmark for adults is at least 150 minutes of moderate-intensity activity a week — a target far easier to hit through small blocks built into the week than through one high-effort event.

A format that works with this evidence, not against it

• Replace daily logging with scheduled blocks. Instead of "log your steps every day," put a recurring 10-minute walk on the calendar for the whole team at the same time each day, opt-out rather than opt-in. Attendance research on workplace events consistently shows defaulting people in beats asking them to sign up.
• Make the activity concrete, not vague. "Move more" loses to "a 10-minute walk" or "10+ bodyweight squats" — something a tired brain doesn't have to invent on the spot.
• Get a leader to go first, visibly. The German study found leaders moved more during the challenge; make that visible instead of incidental — a manager who blocks their own walk and says so in the team channel does more than any leaderboard.
• Build in the exit ramp for remote staff. Given the documented gap in perceived barriers, make the lowest-effort version — a block on a personal calendar, no app, no group required — count as full participation, not a consolation prize.
• Measure attendance in week six, not signups in week one. Both studies above lost most of their sample well before the finish line; track who's still showing up partway through, and treat that number as the real success metric.

(This same logic — scheduling the thing instead of asking people to remember it — is what our extension, TinyTimeouts, automates for individual breaks: it finds the open slots in someone's own Google Calendar or Outlook and books short movement breaks into them by default.)

A challenge you can run again next quarter, with most of the same people still in it, beats a bigger one that only the already-active third of the company ever joined. Start with the schedule, not the scoreboard.
