What Is General Strength?
General strength refers to exercises, movements, and muscle groups that are not specific to the running motion or that don’t contribute directly to propelling you forward as quickly and efficiently as possible. These types of exercises are called “running specific” training, which you often find in running-specific core work, form drills, and plyometric routines.
However, general strength exercises can still help prevent injury and improve your performance. They serve as the backbone to helping you become a stronger overall athlete, which allows you to handle a greater workload (i.e. more intensity and/or greater mileage).
