A gym membership is a subscription that allows individuals to access fitness facilities and services. Members typically pay a monthly or annual fee, which grants them entry to workout equipment, group classes, and sometimes additional amenities like swimming pools or saunas. Many gyms offer different membership plans, catering to various needs and budgets. Some may include perks such as personal training sessions or discounts on fitness products. It's important for potential members to compare options and read the terms before committing to a specific gym or fitness center.
