Things that make use of your lower abs, as highlighted by a recent C-section:

• going up and down stairs
• washing your hair in the shower, and other activities that involve reaching over your head
• closing your car door, and other activities that involve twisting
• getting up out of chairs, out of bed, and off the floor
• coughing, laughing, or sneezing
• supporting the weight of a 2 and a half year old girl, as she decides to use your arms as a vine, while demonstrating how she is exactly like a giant monkey

But luckily, sitting on the couch is a-okay.
