The .fitness extension is a generic top-level zone, so it is not tied to any country. The word fitness refers to physical training and an active way of life, and it is used for gyms, trainers, sports clubs, exercise classes and apps that help people train. A name in .fitness tells visitors at once what the site is about. Use the availability form just below this text to see whether your name in .fitness is still free.

A short history
The .fitness zone was added to the domain namespace during the wider expansion that brought many subject words into use as generic endings. Typical users include gyms, personal trainers, studios, sports clubs and publishers of training guides, as well as developers of applications for planning workouts. Because the subject is widely understood, the ending needs little explanation, although many visitors still know .com better.
Who runs it
The zone is run by a registry operator under a contract with ICANN, the organisation that coordinates the global domain name system. The operator sets the registration policies and works with accredited registrars, who sell names to customers and send the orders to the registry. Policies can change over time, so the terms shown when you order are the ones to read. Registration terms cover the name and its holder, so check them separately from any rules that apply to the content you publish.
Rules in practice
- Open use: generic zones are usually open to any applicant, although the operator may set rules on acceptable content.
- Contact data: the holder's details must be accurate, and the registrar may ask you to confirm them.
- Characters: names use letters, digits and hyphens, within the general length limits of the domain system.
- Renewal: enable auto-renewal and keep the contact address active, so that the name does not lapse during a busy season.
Who uses .fitness
- Gyms, studios and training centres that present their classes and opening times.
- Personal trainers and coaches who share their programmes and booking details.
- Sports clubs, running groups and cycling teams that gather members around an activity.
- Developers and publishers of workout apps, training guides and equipment reviews.
Strengths
- The word states the subject of the site at once, which helps people who are looking for training or classes.
- The name is short and easy to say, which helps when you tell someone about a class or a club.
- The zone is not tied to a country, so an online programme can reach people in several places.
Things to keep in mind
- A name is only an ending, and it does not make any claim about results true. Wording about health and results should be cautious and accurate.
- Advertising rules in many countries limit statements about health and outcomes, so check the local rules before you publish promises about a programme.
- Reviews and before-and-after stories need care. They should be genuine and should not suggest a guaranteed result.
- Many good names are already registered, so prepare alternatives that describe your activity.
Tips before you register
- Check the same name in .com and in the social networks you plan to use for classes and news.
- Publish your opening times, location and contact details as plain text, so visitors can find you without searching elsewhere.
- Describe your programme honestly, including the level of experience it suits and any safety notes that apply to your activity.
- Set SPF, DKIM and DMARC records before you send booking confirmations or newsletters from the domain.
- Enable auto-renewal and protect the registrar account with two-factor login.
Frequently asked questions
Can I promise results on a .fitness site? The ending does not change the rules that apply to your claims. Promises about results and health are often regulated, so keep statements modest, accurate and supported by evidence you can show.
Is .fitness only for gyms? No. Trainers, clubs, apps, training guides, equipment shops and online programmes can all use the ending.
Does .fitness help a site appear in search results? No ending can promise a ranking. Clear content, accurate details and genuine links matter far more.
