Get six-pack abs with this 15-minute workout

#5. Windshield Wipers

– Lie on an exercise mat, keeping your back flat with no arching of the spine.

– Extend your arms out beside you at shoulder level, with your palms pressed firmly to the floor. Your upper body should form a “T” shape.

– Raise your feet off the floor by bending your hips and knees to 90 degree angles. This is the start position.

– As you exhale, rotate both your thighs to one side until the outer thigh touches the ground or until you feel a stretch in your abs and lower back.

– Pause briefly, then rotate to the other side without pausing in the start position.

– When you have rotated to both sides, that is one repetition.

– From a supine position, lying on your back, the knees are bent and pulled into the chest.

– The arms are wrapped around the knees with the chin tucked in towards the sternum like a turtle going into its shell. The gaze is inward.

– Roll up to a sitting position.

– Roll back, holding your spine round.

#7. Boat/Half boat

– From a seated position the hands are gripped around the back of the legs and the knees are bent in a 90 degree angle. Both legs are pulled in towards the abdomen. The core is engaged to maintain balance on the sits bones (be sure that the back does not round). The front of the torso lengthens between the pubis and top of the sternum as the spine extends in both directions reaching up to the sky and rooting down to the earth.

– From a seated position the feet are lifted up so that the thighs are angled about 45-50 degrees relative to the earth. The tailbone is lengthened into the earth and the pubis pulls toward the navel. The shoulder blades are spread across the back and the hands reach around the back of the calves, with legs pulled towards the body.

– Slowly move from a Boat to a Half Boat.

8. Oblique V-Up

– Lie flat on your right side with legs together and slightly forward.

– Put your right arm on the mat and left hand behind your head.

– Crunch up in a V, getting up on your hip and butt.

– Keep your legs straight.
