Exercise creates physical stresses in the body that trigger the adaptive response that changes us physically. The pathway through which this change happens requires hormone signals that activate specific cellular mechanisms. The gut is home to a host of bacteria that form our microbiome. The activities of the gut microbiome affect our physical capabilities including speed, explosiveness, endurance and even VO2 Max (a.k.a. aerobic capacity). The microbiome also responds to hormone signals that help good bacteria thrive and bad bacteria die out. That means that exercise also helps us maintain good gut health. The Gut is a workout that sets you down the path to help your gut bacteria help you get fitter, stronger and healthier.
