Planet Fitness gym growth
Chartr's bar chart drew 2.1K views on X: 1.0x its typical post and #13 of 23 Chartr charts we track by views. Read Oct 10, 2026.
After a new round of New Year's resolutions, Planet Fitness now has nearly 20 million members
Why it spread
It spread mainly because it hit a hot topic that week and had polished design, though the measured numbers show only 3 likes, 1 repost, 0 quotes, 0 saves, and 2,097 views, which is 0.4 times the account's normal performance and below its typical 7 likes.
What worked
- The post tied into a timely New Year's resolutions theme, which was a hot topic that week.
- The chart had polished design and medium self labelling, making it visually clear.
- It used a simple bar chart to show Planet Fitness gym count increasing annually, with a source line included.
What to borrow
We could use a simple bar chart with a clear source line to frame our own data around a timely topic, while keeping design polish medium and self labelling medium.
Careful
Do not over read the spread as strong engagement, since the measured numbers are low: 3 likes, 1 repost, 0 quotes, 0 saves, and 2,097 views, which is 0.4 times the account's normal and below its typical 7 likes.
