First, the closer the gym is to your home, the better. After all, even if you are an avid sports fan, sometimes there is an obsessive desire to sit at home. A fitness club 5 minutes away greatly reduces the likelihood that you will miss a workout. You can also meet neighbors or make friends with those who live nearby, too.
Take a word of mouth advantage. Talk to neighbors, friends, relatives. You can even talk to your movers. Ask them how they maintain a good physique for the job. Google the nearest sports clubs. If you like CrossFit, write "nearest CrossFit gym" that way you'll quickly find a dozen options. The most appropriate one will become your new gym. Mark the locations of possible gyms on the map and visit them one by one.
Once you enter the fitness club, talk to the trainers. Because they are the heart pumping all the people inside the club. You will communicate with them most of the time. Talking is good but it is much better to watch how they work. Observing from the side, you will quickly understand if the trainer suits you or not.
Pay attention to the overall condition of the gym, equipment, showers, and locker rooms. Ask the staff how often the place is cleaned, learn about the availability of training equipment during peak hours, the degree of occupancy of the gym, and so on.
Take personal needs into account. For example, you want to do yoga, in which case the traditional gym will hardly suit you. After all, for yoga classes, you need a relaxed atmosphere, not the bustle of the fitness room and guys in sweaty T-shirts.
Perhaps you need access to a pool or spa. Think about specifics in advance.
Last but not least, the pricing and season ticket system. Find out about payment options, subscriptions, and the ability to visit fitness clubs from the same network as your gym.
