Fitness tracker manufacturer Fitbit has published its first ever Fitbit Activity Index, using the logged activities of over 1m users to create a picture of emerging fitness trends in a variety of areas around the world.

The anonymised data covers the US, Australia, UK and Canada, and can be broken down by location, age and gender, providing fascinating insights into health and exercise habits. Walking was the most common exercise across all demographics, with 70 per cent of surveyed users walking for fitness, so Fitbit decided to eliminate it from the results and dig down deeper into other activities.

Beyond walking, running, biking and swimming were the top three most popular activities in the UK, with running taking the top spot for both millennials and Generation X, while biking proving the most popular activity for Baby Boomers.

UK users proved receptive to the latest trends in fitness, with activities like Cross Fit and Insanity appearing on the list for both men and women aged 18-55. Meanwhile, the British weather appears to have had an impact on UK habits, with indoor activities like aerobics and indoor cycling more popular here than in the US, Australia or Canada.

“The new data from the Fitbit Activity Index is really exciting for us, as it provides some brand new insights into how Brits are keeping fit,” said Gareth Jones, vice president and general manager of Fitbit EMEA. “Its great to see the power-trio of running, swimming and cycling topping the list of most popular activities, but its also nice to see some of the more everyday activities, such as gardening, making the list.”
