    The 7 Pillars of Optimal Health: Why Muscle Is an Organ of Longevity

    Send us Fan Mail What if building muscle isn't just about looking better—but about living longer, staying independent, and maintaining your health as you age? In this episode of the Fit Rx Health & Wellness Podcast, Dr. Greg Dennis continues the 7 Pillars of Optimal Health series with Pillar #3: Movement & Strength. Exercise has been a major part of Dr. Dennis's life for more than 30 years, but the reasons for exercising have changed. What may start as a desire to build muscle or improve appearance becomes something much more important as we age: preserving strength, metabolic health, mobility, and the ability to keep doing the things we love. In this episode, Dr. Dennis discusses: Why skeletal muscle can be thought of as an organ of longevityThe powerful relationship between physical fitness and lifespanHow muscle helps regulate blood sugar and improve insulin sensitivityWhy maintaining muscle becomes increasingly important as we ageThe connection between strength training, bone health, mobility, and independenceWhy simply walking is important—but isn't a complete exercise programHow often you should strength trainWhat progressive overload means and why it mattersWhy cardiovascular fitness is just as important as strengthWhat Zone 2 cardio is and how to incorporate itWhat VO₂ max measures and why it's such an important marker of longevityHow high-intensity intervals such as the Norwegian 4x4 can improve aerobic fitnessHow to balance strength training, Zone 2 cardio, and VO₂-max trainingDr. Dennis's own weekly exercise routine and how he approaches training for both muscle and longevityYou don't have to become a bodybuilder or an endurance athlete to benefit from exercise. The goal is to move every day, build and preserve muscle, and develop the cardiovascular fitness necessary to remain capable throughout life. Muscle isn't just about appearance. Muscle is freedom. It helps preserve your ability to work, travel, climb stairs, carry groceries, play with your children or grandchildren, recover from illness, and maintain independence as you age. Don't just exercise to weigh less. Train for the life you want to be capable of living. This is the third episode in the 7 Pillars of Optimal Health series from the Fit Rx Health & Wellness Podcast.

    The 7 Pillars of Optimal Health: Nutrition — Your Diet Doesn't Need a Name

    Send us Fan Mail Keto. Carnivore. Vegan. Mediterranean. Low-carb. Low-fat. With so many competing opinions about nutrition, eating for health and longevity has become unnecessarily complicated. In this episode of the Fit Rx Health & Wellness Podcast, Dr. Greg Dennis continues the 7 Pillars of Optimal Health series with Pillar #2: Nutrition. After years of studying nutrition, longevity, and metabolic health—and seeing what works in clinical practice—Dr. Dennis shares how his own thinking about nutrition has evolved. Rather than following a diet with a particular name, he believes the foundation of good nutrition can be surprisingly simple: prioritize protein, eat mostly real whole foods, maintain a healthy body composition, and individualize carbohydrate and fat intake based on your metabolic health, activity level, and goals. In this episode, you'll learn: Why calories still matterWhy protein becomes increasingly important as we ageThe connection between muscle, metabolic health, and longevityWhether red meat belongs in a healthy dietWhy healthy fats are beneficial—but aren't unlimitedWhy carbohydrates aren't necessarily the enemyThe difference between whole-food carbohydrates and highly processed foodsWhen low-carb and ketogenic diets may be useful therapeutic toolsThe pros and limitations of vegan, vegetarian, and carnivore dietsWhy ultra-processed foods may be a much bigger problem than any single macronutrientWhat Dr. Dennis actually eats and how his own approach to nutrition has changed over the yearsThe takeaway is simple: your diet doesn't need a name. For most people, building meals around quality protein and minimally processed whole foods—while limiting the highly processed foods that dominate the modern diet—is a sustainable foundation for metabolic health, maintaining muscle, healthy aging, and longevity. This is the second episode in the 7 Pillars of Optimal Health series.

    The 7 Pillars of Optimal Health: Why Better Health Starts With Sleep

    Send us Fan Mail What if improving your health isn't about finding the perfect diet, supplement, medication, or exercise program—but about strengthening the foundations that everything else is built upon? In this episode of the Fit Rx Health & Wellness Podcast, Dr. Greg Dennis introduces the 7 Pillars of Optimal Health: Sleep, Nutrition, Movement & Strength, Hormonal Health, Emotional Health, Relational Health, and Spiritual Health. We begin the series with one of the most important—and most overlooked—pillars: sleep. Sleep plays a critical role in hormone balance, metabolism, weight management, muscle recovery, brain function, emotional health, and longevity. Yet many people struggle with poor sleep while focusing on supplements or medications before addressing the fundamentals. In this episode, Dr. Dennis discusses practical ways to improve sleep, including: Creating a consistent sleep scheduleUsing morning sunlight to support your circadian rhythmOptimizing your nighttime routine and sleep environmentHow caffeine and alcohol affect sleep qualityThe relationship between exercise, stress, and sleepSupplements such as magnesium, melatonin, glycine, L-theanine, and apigeninWhen poor sleep may point to an underlying issue such as sleep apnea, hormonal changes, chronic stress, or metabolic problemsYou'll also get a simple approach you can begin using tonight to start improving your sleep. This is the first episode in the 7 Pillars of Optimal Health series from Fit Rx Health & Wellness. Over the coming episodes, we'll explore each pillar and how they work together to improve health, performance, and longevity. Support the show

    Advanced Shockwave Therapy for Sexual Health and Musculoskeletal Pain

    Send us Fan Mail In this episode, we explore the science and evolution of shockwave therapy and why it has become a powerful tool in regenerative medicine. Our guest, Chrislyn Chaloupka, FNP has over a decade of clinical experience as both a seasoned nurse practitioner and the Director of Clinical Services at Omniwave/Gainswave. She has spent years applying shockwave therapy in her own practice, particularly in sexual wellness, and brings a wealth of knowledge on where shockwave delivers the strongest outcomes and specifically the OmniWave® therapy and why this next-generation device represents a major step forward in treatment effectiveness and versatility. We discuss the physiology behind shockwave therapy, including how targeted acoustic soundwaves stimulate blood flow, angiogenesis, cellular repair, and tissue remodeling. You’ll learn why these mechanisms are so effective for men’s sexual wellness, women’s sexual health, and chronic musculoskeletal pain—conditions that often persist due to poor circulation and incomplete healing. This conversation breaks down: How OmniWave differs from earlier shockwave devicesWhy improved blood flow and tissue regeneration matter for sexual healthThe role of shockwave therapy in treating tendon, ligament, and soft-tissue injuriesWhy non-invasive, regenerative therapies are reshaping modern medicineWhether you’re curious about sexual wellness, chronic pain solutions, or the future of regenerative therapies, this episode provides a clear, science-based look at how OmniWave therapy works—and who may benefit from it.  #FitRxHealthAndWellness #WellnessPodcast #RegenerativeMedicine #ShockwaveTherapy #OmniWave #GainsWave #MensHealth #MensSexualHealth #WomensSexualHealth #IntimateWellness #MusculoskeletalHealth #PainRelief #BloodFlowMatters #NonInvasiveTreatment #PhysicianLedCare  Support the show

    A Turning Point for Women’s Hormone Therapy: The Black Box Warning Is Gone

    Send us Fan Mail For decades, women were told that hormone replacement therapy was dangerous — largely due to a deeply flawed study that created fear, confusion, and misinformation around female hormones. In a long-overdue move, the FDA has now removed the black box warning on hormone therapy for women, signaling a shift back toward science. In this episode, Dr. Greg Dennis breaks down why the warning existed in the first place, what went wrong with the original research, and why properly prescribed hormone replacement therapy is one of the most powerful tools for women’s long-term health and quality of life. We discuss the benefits of starting HRT early, why choosing the right provider matters, and the pros and cons of today’s treatment options — including pellets, creams, injections, and patches. This is an honest, science-based conversation about why female hormone replacement therapy deserves a second look — and why it may be one of the best decisions a woman can make for her health.

    Targeting Cancer at the Molecular Level: Repurposed Drugs and Integrative Strategies

    Send us Fan Mail Today, I’m joined by Dr. William LaValley — one of the world’s leading researchers and medical doctors in the field of integrative cancer treatment. Dr. LaValley has spent decades combining the latest discoveries in molecular biology with evidence-based, integrative therapies for cancer. He draws upon the vast database of research available through PubMed to identify the anti-cancer potential of natural compounds and repurposed, or off-label, pharmaceutical drugs. Since earning his M.D. in 1986, Dr. LaValley has developed sophisticated, evidence-driven databases mapping the molecular pathways of cancer. These insights have allowed him to design personalized treatment protocols that complement — rather than replace — conventional chemotherapy and radiation therapy. In this episode, we’ll discuss how understanding molecular biology helps identify new targets for treatment, how repurposed drugs can work synergistically with standard therapies, and what the future of integrative oncology looks like.
