National Fitness Day takes place on Wednesday 24th September 2025 – a nationwide celebration of the role that physical activity plays in our health and wellbeing.
It’s the perfect opportunity to inspire your team to move more, connect with each other, and discover new ways to stay active.
If you’re looking for ideas on how to mark the day at your company, here are some tried-and-tested ways to get started.
1. Host a Fitness Class in the Office
Bringing movement into the workplace is one of the most effective ways to engage your team. That Day can deliver a wide range of sessions on-site or online, including:

2. Take on a Fitness Challenge
Challenges are a great way to get everyone involved, no matter their fitness level. Here are some ideas you can roll out on the day:
- Step count challenge – encourage staff to track their steps and compare totals.
- Desk stretch breaks – set alarms every hour for a quick posture reset.
- 10-minute workout bursts – try mini circuits that can be done at desks or in meeting rooms.
For inspiration, try our Beginner’s Fitness Challenge: The 3x2 Method – a simple weekly routine of strength, cardio, and stretching.
3. Start Small With Bands and Bodyweight
Not everyone has access to a gym, but with a resistance band or just bodyweight, you can achieve an incredible workout.

4. Launch a Workplace Running Club
Running is one of the most accessible ways to move more – and doing it as a group makes it fun and social.
We’ve put together tips on How to Start a Running Club at Work, plus That Day can provide expert-led running sessions to get your colleagues started.
5. Make It Stick Beyond National Fitness Day
The most important part? Keep the momentum going.
Use the day as a launchpad for weekly wellbeing initiatives:
- A regular lunchtime or after work running group
- A yoga or Pilates class once a week
- Monthly mobility and posture workshops
- Workplace fitness challenges with small prizes
- Subsidised gym scheme
- On-site gym or wellness space.
