Fab Abs

Circle Crunch

Works upper and lower abs and obliques.

These ab crunches work your muscles from every direction, and the continuous motion forces you to hold your core tight, adding and extra punch to this exercise.
Lie face up with your knees bent and feet flat on the floor, hands behind your head. Lift your shoulders off the floor until you feel a tight contraction now curl your torso around in a small clockwise direction (start from 6 to 9 to 12 to 3 and back to 6). For the next rep, repeat in the opposite counter clockwise direction.

Double side jacknife

Works obliques (whittle that waist)

Lie on your left side, your legs stacked and straight. Wrap your left arm in front of your torso, placing it on your right hip, and put your right hand behind your head. Simultaneously raise your torso and legs, bringing your head towards your hips. Return to start in a controlled motion and repeat for all reps, then switch sides and repeat reps to complete one set. If this is too difficult, begin by lifting only your legs, and gradually build up your strength.
