• Diabetes and Exercise: How Exactly Muscle Movement Manages Blood Sugar

  Dynamic Aging Retreat Oct 3-5 2025This Episode's Show NotesJoin Our Newsletter: Movement Colored GlassesIn this episode, Katy Bowman and Jeannette Loram dive into the fascinating relationship between blood sugar, diet, and movement. They unpack how the body regulates blood sugar, what happens when this process breaks down in Type I and Type II diabetes, and why different kinds of activity play such a big role in prevention and management.Katy and Jeannette explain how contracting muscles can pull glucose directly into working cells during exercise—a powerful but site-specific effect—and how long-term training reshapes muscle to take up glucose more efficiently.They also compare the blood sugar benefits of endurance exercise, resistance training, HIIT, stretching, and even light daily movement. Along the way, they highlight two key scenarios: insulin resistance linked to excess weight and inflammation, versus insulin resistance driven by low muscle mass in people with normal weight. For the latter, they stress why resistance training—or “big body work”—is especially essential.CHAPTERS 0:06:00 - Definitions 0:16:00 - The Dynamic Collective 0:17:00 - You Can’t Exercise Off Diabetes 0:20:00 - Muscle is the Key Tissue (and the Liver)0:36:30 - Stretching & Light Activity 0:47:00 - Exercise Modality for Blood Sugar Regulation0:54:25 - Listener Question on Lupus brought to you by Peluva 1:09:09 - Blood Sugar Spikes During Exercise BOOKS & RESEARCH PAPERS My Perfect Movement Plan by Katy BowmanI know I should Exercise, But... by Diana Hill & Katy BowmanExercise and GLUT4 by Flores-Opazo et al (2020) Mechanisms of endurance and resistance exercise in type 2 diabetes by Zhao et al (2025)  Sedentary behaviour as a mediator of type 2 diabetes by Hamilton et al (2015) Impact of reduced sitting time or increasing sit-to-stand transitions on blood pressure and glucose regulation in Postmenopausal women by Hartman et al (2025) The impact of standing desks on cardiometabolic and vascular health by Bodker et al (2021) MADE POSSIBLE BY OUR WONDERFUL SPONSORS:Sweet Skins, organic hemp and cotton clothing that is stylish, flexible and designed to move with you, take 20% off with code Movement20Peluva, Five-toe minimalist sports shoes ideal for walking and higher impact activities.

• Can Exercise Fix Aging Eyes?

  Dynamic Aging Retreat Oct 3-5 2025This Episode's Show NotesJoin Our Newsletter: Movement Colored GlassesIn this episode, Katy Bowman and Jeannette Loram have a fascinating and wide-ranging conversation with neuro-optometrist Dr. Bryce Appelbaum.Dr. Appelbaum breaks down the crucial difference between eyesight—what you can see—and vision—how your brain interprets what you see and turns it into action. Together, they explore the striking parallels between physical and visual health, highlighting how prolonged screen time and visual inactivity can stiffen our eye muscles just like sedentary habits stiffen our joints. Focusing on screens all day is like clenching your fist nonstop—leading to eye strain, headaches, and long-term issues like poor eye coordination, which can affect depth perception, balance, and even increase the risk of falls.The conversation covers everything from visual tics and dry eyes to how vision is connected to musculoskeletal alignment and behavior—and even offers a glimpse into the future of eye health in our tech-heavy world. Dr. Appelbaum also shares how anyone can improve visual stamina and flexibility, and Katy and Jeannette reflect on their personal experience with his online program ScreenFit—a movement program for your eyes!

• What to Do When Rucking Or Carrying Heavy Loads Hurts

  Dynamic Aging Retreat Oct 3-5 2025This Episode's Show NotesJoin Our Newsletter: Movement Colored GlassesBiomechanist Katy Bowman and biologist Jeannette Loram talk about rucking—walking with weight on your back—and other modes of carrying. They touch on the evolutionary history of carrying, carrying in modern Hunter Gatherer populations, rucking in the military and the benefits of fitness rucking. Jeannette and Katy focus on the challenges associated with rucking particularly pain and discomfort. They explain how different body adjustments—like leaning forward, arching the back, or shifting the hips forward—are responses to offset the backward-pulling force of a heavy load. These shifts help accommodate the extra mass, but if a single adjustment is done repetitively or without muscular support through the core, pain can be the result. Listen in to discover a more varied and mindful approach to managing your ruck; your low back will thank you!CHAPTERS  00:06:00 - The Dynamic Collective 00:07:00 -  Are Humans Born to Carry? 00:13:00 - Phases of Life and Issues with Fitness Rucking and Carrying in General  00:26:00 - What's Holding You Up?

• Dynamic Wardrobes: How Clothes Can Restrict, Encourage or Stabilize Movement

  Dynamic Aging Retreat Oct 3-5 2025This Episode's Show NotesJoin Our Newsletter: Movement Colored GlassesBiomechanist Katy Bowman and biologist Jeannette Loram get into a nuanced discussion about clothing, specifically the idea that how you get dressed might be impacting the way that you move or the movement choices you are able to make. Katy and Jeannette highlight how stiff or excessively baggy clothing might be ‘casting’ movement. On the flip side ‘stabilizing’ wear like well-designed bras and compressive garments can make movement more comfortable for certain activities. Katy offers advice on how to dress for multiple scenarios: the movement that you plan to do, the spontaneous movements that you might want to do, as well as all the other things you need to do in a day.Also in this episode Katy speaks with Mira Fannin of Sweet Skins. Sweet Skins produce beautiful hemp-cotton organic clothing. Katy and Mira talk about the origin of Sweet Skins and how Mira’s goal to make cute and liveable clothes for busy women has created the perfect movement-friendly clothing line. They also talk about the famous Bike Time pants and the new Sweet Skins styles coming out very soon.
