Inside Your Engine: What Really Happens When You Exercise

In this first episode of our three-part series, “Exercise vs. Training,” we explore the intricate workings of our muscles and the energy systems that power them. Discover how every day, we recycle our body weight in energy molecules, enabling us to perform everyday tasks like lifting grocery bags or sprinting. Our muscles are not merely passive structures; they are dynamic engines made up of around 600 muscles, each composed of fibers that work in pairs to create movement. We delve into the microscopic level, examining myofibrils and sarcomeres, the fundamental units responsible for motion. Learn how signals from the brain initiate muscle contractions and the vital role of ATP, the energy currency of our cells, in fueling these actions. Tune in to understand the fascinating science behind movement and the importance of exercise in our daily lives.Link to my substack: https://drlauriemarbas.substack.com/p/inside-your-engine-what-really-happens?r=4t8jxgA Big Thank You To Our Sponsors: If you want the best supplement to help you on your plant-based journey, you have to try Complement: https://lovecomplement.com/?aff=62If you are over the age of 50 and want to improve your body composition, build lean muscle (combat sarcopenia), build stronger bones (to combat osteoporosis), and you want to feel your best, I highly recommend exploring the life-changing coaching offered at https://www.fitvegancoaching.com/ Their personalized, whole-food, plant-based approach helped me lose 7% body fat, gain lean muscle, and even improve my running time—all while feeling energized and healthy.
