Everyone wants to get a sexy flat 6 pack abs, yet it seems to be the most difficult part of the body to lose weight and gain muscle. Your abdominal area consists of three muscle groups, the upper abs, lower abs and the oblique muscles.

Lower abs muscles are the hardest to train primarily because not many exercises specifically target your lower abdominal muscles. Here are some lower abdominal exercises you can try at home.

Double leg lifts. Lie on your back, hands under your buttocks, palm facing the floor. Then lift your legs up vertically 90 degrees. Lower them after a few seconds. Slowly, reduce the angle of your legs against the floor until they are only a few inches off the floor. Repeat this 5 to 8 times.
