To identify what a specific activity stretches, it would be helpful to know the details of the activity itself. However, generally speaking:
-
Hamstrings: Stretched by activities like forward bends, seated toe touches, or standing leg stretches.
-
Deltoids: Stretched by arm cross-over stretches or overhead arm stretches.
-
Quadriceps: Stretched by standing quad stretches or lunges.
-
Abdominals: Stretched by backbends or cobra stretches.
If you have a specific activity in mind, please provide the details and I can give you a more precise answer!
