Side Crunches (abs)

Side Crunches isolate the obliques, which helps with the rotational power used in sports like football as well as a tighter side-cut look.

Lie on your back or side with knees bent and let them fall to one side. Curl your ribcage toward your hip on that side, focusing the movement in your obliques rather than your hip flexors, then switch sides after completing your reps.
