Which types of credit cards are accepted at Planet Fitness?

The correct choice specifies that Planet Fitness accepts Visa, American Express, and MasterCard. This confirms the gym's commitment to providing convenient payment options to its members, allowing them to use widely recognized credit cards for their memberships and services. Visa and MasterCard are two of the most commonly used credit card types globally, making it easier for members to manage their payments. By also accepting American Express, Planet Fitness caters to a broader customer base, including those who prefer to use this particular card for its benefits, such as travel rewards or fraud protection.

The other options reflect limitations that do not align with Planet Fitness’s actual credit card acceptance policy. For instance, while it’s common for many businesses to accept only major credit cards, limiting to Discover or only to cash payments would unnecessarily hinder members' flexibility in payment methods. Understanding the accepted payment methods is crucial for ensuring a seamless experience for members.
