Lower ab exercises are a vital part of any workout program especially for athletes. This area helps in firming up the stability of the spine. A strong abdomen likewise helps in the prevention of back injuries. There are two muscle groups- the rectus abdominus which is lined up along the abdomen and works by pulling the pelvis towards the belly button, and the transverse abdominus located across the abdomen and pulls the belly button towards the spine.
