Working the External Obliques and Internal Obliques
Oblique muscles fibers are diagonal muscle fibers. The muscle fibers of the external obliques run in the opposite direction of the internal obliques. X marks the spot on your love handles! The internal obliques, as you might have guessed, lay deep beneath the superficial external obliques. Both the internal and external obliques are best strengthened with core exercises that involve a diagonal movement.
