Great Lower ab workout..

Lay down, and lift your legs up. make sure you're using your abs and not momentum though!
alternatively you can bend your legs like that and lift your tushie up with your abs

You can do Mountain Climbers,
You position your self in the downward dog position same as in yoga and bring your knees into your chest one at a time

flutter kicks are good lay down on a bench if you have one and alertane your legs one up one down ten times then hold your feet together for 3 secs. thats one rep. try 60... or you can do the p90x scissors one leg off the ground and one in the air count to three and switch, and there are heels to the heavens too lay flat on your back legs as straight as you can get them and plus your butt up you will feel the burn....;)

I was looking for suggestions as well...thanks that is one I can defiantly do at home.

Is it controversial on MFP to say there's no such thing as lower abs? If you your lower abdomen is protruding it's probably excess fat. The muscles that connect your torso run continuously from top to bottom--one on each side, so there is no lower ab muscle. Planks have always worked for me to reduce protrusion, as well as any exercise (kickboxing, tae bo, capoeira) that involves kicking above the waist. Leg raises, etc...are all good exercises, but their really just different ways of working the exact same muscles you work for "upper abs."

Actually, you have four major abdominal muscles. Transversus abdominis, rectus abdominis, and the internal and external obliques.

The transverse abdominis has the effect of pulling in what would otherwise be a protruding abdomen (hence its nickname, the “corset muscle"). This is the main muscle being worked in most of the workout recommendations in this thread.

Other more traditional ab workouts (such as crunches) target the rectus abdominis, while engaging the other muscles as secondary.

Don't get me wrong, you still need to lose the fat to make the pooch go away completely, but it does actually play a role in having a flat tummy.
