Twist Crunchies. This one is similar to the Bicycle Crunch Pump but you'll keep both feet on the floor. Instead, your alternate one corner of your upper torso toward the opposite knee without lifting the knees. This is great for the upper abs and obliques. Do three sets of 15-25 reps. Some pointers, don't pull your head too far forward or lift the lower back.
