A flexibility program should be based on what primary principle?

A flexibility program should be based on consistent training because flexibility improvements require regular and ongoing practice of stretching exercises. Consistency helps in progressively increasing the range of motion and reducing muscle tightness over time. Unlike strength training that may focus on overloading or resistance, flexibility gains are largely achieved through repeated, purposeful stretching sessions. This ongoing commitment to flexibility routines can help in preventing injuries, increasing overall mobility, and enhancing sports performance.

The other concepts, such as overloading the muscles, variability of stretches, and progressive resistance, play significant roles in strength training but are not the primary focus for flexibility programs. Flexibility training does not centralize around progressively increasing resistance; rather, it emphasizes the regularity and quality of stretching to achieve desired outcomes. These principles are more applicable to strength workouts rather than flexibility enhancement.
