Which of the following is an example of readily achievable barrier removal for fitness facilities to improve accessibility?

Selecting "All of these" is appropriate because each option listed represents a specific action that can be taken to improve accessibility in fitness facilities.

Implementing curb cuts is critical for allowing individuals using wheelchairs or mobility devices to navigate easily from sidewalks to entrances, creating a seamless transition that enhances accessibility. Lowering soap dispensers in restrooms ensures that individuals of shorter stature or those using wheelchairs can reach hygiene facilities comfortably, which is essential for both usability and dignity. Additionally, lowering door pressures means that doors can be opened with less force, making them more accessible for individuals with weak grip strength or limited upper body mobility.

All of these actions are considered readily achievable because they often require minimal alterations or modifications that can be executed without significant financial burden or extensive construction work, therefore facilitating an inclusive environment in fitness facilities.
