January is a fresh start and the busiest month of the year so if you're not doing so already now might be a great time to start appealing to all of those people who are feeling guilty about their Christmas excesses and ramp-up your memberships.
How these stats are collated
These monthly statistics are generated using an anonymous set of 40 gyms throughout the UK chosen at random. Each month the same gyms are used to keep the results consistent and accurate. to meet print and publication deadlines months are calculated as the 16th of the previous month to the 15th of the current month.
