Lower Ab Workout
Once you get more experienced with your lower ab workout, you'll probably want to move on beyond basic exercises to do some more advanced ones. I think you'll find the exercises listed here quite a bit more challenging, but they're also more effective for focusing your lower ab workout.
Keep in mind that your abs are some of the strongest muscles in your body. To have the most impact on them you will want to work them almost to the point of fatigue.
V-Sit: Lie flat on your back with your hands facing down. Simultaneously raise your knees and your torso off the floor until your hips and knees are flexed and your thighs are close to or touching your chest. Hold this position for about a second, then gradually lower your torso and legs back to the ground where you started. For added difficulty in this lower abs workout you can try to not rest your torso and legs on the floor in between repetitions. Instead you would keep your torso and legs about an inch above the ground at all times.
Alternating Leg Walks: Begin your lower abs workout by lying on your back, placing your hands under your butt, and take a few deep breaths. Then, contract the lower ab muscles and lift your right leg up slowly, until it is 90 degrees to your body. The, equally slowly, lower it back down, until it is a few inches off the floor, while simultaneously raising your left leg. Keep lifting your legs alternatively about 8-10 times to begin with. Later, as your abs become stronger, you can increase the count to 15-20 reps and lift your head and shoulders off the floor while performing the exercise.
Double Leg Reverse Crunches: Lie down on your back, with your hands under your butt. Lift both your legs up until they are in a vertical position. Now bend your legs at the knees, so that the lower part is parallel to the floor. Then, contracting your lower abs, and maintaining your bent knees, gradually lower your legs until the soles of your feet are just a couple of inches off the floor. Keep your abs contracted and hold this position for a few seconds. Then increasing the contraction in your abs, lift your knees up again, bringing them towards your chest. This is a somewhat challenging exercise, so begin your lower back workout by doing just 3-5 reps. Later, as you feel yourself getting stronger, increase the reps gradually, until you can do 15-20 reps.
It is essential to do these exercises slowly. If you do them too fast, momentum kicks in, and the exercises become ineffective. And please note that some of these exercises require you to place your hands under your butt. This is important for avoiding lower back stress. Nothing ruins a lower ab workout faster than developing lower back pain.
