Boxing, kickboxing and Muay Thai are taught in very different rooms — some are fight gyms with a ring and a competition team, others run fitness-style classes where nobody spars. These gyms list boxing or striking classes, so you can pick by what you actually want to do: learn to fight, get in shape, or both.

Good to know
Do I need experience to join a boxing gym?
No. Most gyms run beginner classes that start with stance, footwork and pad work. You will need hand wraps and gloves after the first trial session; many gyms lend gloves at first.
What is the difference between boxing and kickboxing classes?
Boxing uses punches only; kickboxing and Muay Thai add kicks, and Muay Thai adds knees, elbows and clinch work. Fitness kickboxing classes often skip partner drills entirely.
Are boxing classes good for kids?
Many gyms run youth programs focused on conditioning and technique with no head contact. Ask about age groups and whether youth sparring is supervised and optional.

How to drain fluid from ear?
Draining fluid from an ear—often caused by trauma such as cauliflower ear in grappling—requires sterile medical aspiration using a syringe followed by a compression wrap. Performing this procedure at home without medical expertise carries a severe risk of infection and permanent cartilage deformity. Practicing martial artists in Colorado should consult qualified medical professionals or ask coaches at one of the 207 listed local academies for proper sports health protocols.
