Circuit Three: Butterfly Crunch
- Lie on your back with your knees open and the soles of your feet together (in a butterfly position). Lengthen your arms overhead so they are resting on the floor.
- Exhale and bring your hands and knees toward each other performing a full-body crunch. Your shoulder blades should be off the mat as your perform a small reverse crunch lifting your pelvis a bit off the mat. Hold this position for a moment and really feel your abs squeezing.
- Slowly lower your arms and feet back to starting position to complete one rep.
- Do 15 reps to complete a set.
Don't let the sweet name fool you, this move works the abs quite thoroughly.
