It's not just about weight loss. Having great gut health is linked to good health throughout your body. Scientists in this rapidly growing field are finding connections between gut microbes and the immune system, weight loss, gastrointestinal health, , allergies, asthma, and even cancer.

The external obliques are the V-shaped muscles running diagonally down your sides that, along with the internal obliques underneath them, help you rotate your spine when a Ryan Gosling look-alike walks by. The rectus abdominis, meanwhile, is the straight-down-the-center muscle which, yes, can make you appear to have a six-pack if you have a seemingly single-digit body-fat percentage like Ryan Gosling's. The one remaining ab muscle, which Dr. Herrera's surface EMG won't be picking up, is the transversus abdominis. The deepest-down of all, it does a complete wraparound of your midsection and pulls it in like a corset.
