Stomach Vacuum Training Works...I have proof. (time stamps in description)

I added stomach vacuum training to my abdominal workouts a couple of years ago, not expecting much change in my waistline. A week ago, I learned that they do, in fact, work. I demonstrate 2 separate techniques that target the transverse abdominus muscle in 2 slightly different ways, to help you see maximum benefits for toning and strengthening the transverse abdominus. Generally a great exercise to improve the look of your abs in general with many health benefits.
