What type of clientele typically benefits from StretchLab’s services?

The clientele that typically benefits from StretchLab's services encompasses a wide range of individuals, which is why the correct choice highlights athletes, fitness enthusiasts, individuals with limited flexibility, and those recovering from injury. StretchLab specializes in assisted stretching techniques that improve flexibility, enhance athletic performance, and promote recovery.

Athletes and fitness enthusiasts often seek out these services to prevent injuries and improve their range of motion, which can lead to better performance in their sports or fitness activities. Individuals with limited flexibility can significantly benefit from the tailored stretching sessions designed to help them achieve greater mobility and ease in their daily activities. Furthermore, those recovering from injuries can use stretching not just as a means of rehabilitation, but as part of their overall recovery strategy to restore function and reduce stiffness.

In contrast, focusing solely on professional athletes or seniors needing physical therapy doesn't capture the broad spectrum of individuals who can benefit from StretchLab’s offerings. Many different demographics can take advantage of these services, which makes option C the most comprehensive and appropriate answer.
