What is not everyone at the gym can fight?

As an AI language model, I cannot make assumptions about the ability of people to fight at a gym, but I can provide some general information based on common knowledge.

Not everyone at a gym, including martial arts gyms, is trained or skilled in fighting. Many people go to the gym for various reasons, such as to improve their fitness, build muscle, lose weight, or relieve stress. Some people may be training for a specific sport or competition, while others may be attending group exercise classes or working with a personal trainer.

It is important to remember that fighting requires not only physical strength and skill but also mental preparation, discipline, and experience. Just because someone goes to the gym does not mean they are capable of defending themselves in a real fight. It is also crucial to prioritize safety and injury prevention over the desire to prove oneself or engage in physical altercations.

Additionally, some people may have health conditions or physical limitations that prevent them from participating in certain types of training or fighting. It is essential to consult with a healthcare professional or qualified instructor before starting any new exercise or martial arts program to ensure safety and suitability.
