Spider crunch

The spider crunch is a core exercise that begins in a straight-arm plank position and involves raising one knee toward your same-side elbow to target the obliques. It is similar to a mountain climber, but with the knees out wider. It can be performed for time or reps as bodyweight ab training or conditioning.
