This video popped up on YouTube today, and I thought you guys might find it interesting. She actually references a couple studies about the effectiveness of stomach vacuums as an exercise and breaks down the way it works. I don’t know if her results are truly valid, but there might be something to doing stomach vacuums as a part of a daily ab routine.
