A better way to think about easy aerobic work: what you are building, what is limiting you, and why a watch zone is not a lab zone. Zone 2 has become a personality. People defend it the way they defend a political party or a drivetrain. That is a compliment to how useful the idea is, and a problem, because the zone was never the point. Peter Attia put the correction cleanly in a 2026 note: Zone 2 is a means to an end. The end is cardiorespiratory capacity — a wide ability to

Every so often a paper arrives that feels personally targeted. In 2024, researchers at the University Medical Center Groningen published an observational study of 95,210 former international athletes across 44 sports and 183 countries. They asked a simple, rude question: compared with people of the same sex, in the same country, dying in the same year, did the sport you lived inside change how long you lasted? For male athletes, pole vaulting came first: about 8.4 extra years

Phosphodiesterase type 5 inhibitors were designed as heart drugs. They became famous for an entirely different organ. That origin story is not trivia. It is the reason a class of medications most people associate with a late-night commercial is now being discussed, with a straight face, in longevity clinics, cardiology journals, and podcasts that treat 5 mg of tadalafil like a morning vitamin. The question is not whether sildenafil (Viagra) and tadalafil (Cialis) do something

A practical, evidence-based guide to fueling long rides, races, and training days. If you have ever finished a long ride with nothing left in the tank, you already know the problem carbohydrate is meant to solve. Muscle glycogen is finite. Fat oxidation is powerful but too slow when intensity rises. The athletes who stay sharp in hour four are rarely the ones who “just drink when they are thirsty.” They have a plan for how many grams of carbohydrate they will take in each

At Project Blue, we work with athletes who push their physical limits: endurance runners, strength athletes, and high-performance individuals seeking to optimize health and performance. Recently, we cared for a long-distance runner who presented with a mild case of exertional rhabdomyolysis. While not severe enough to require hospitalization, the episode served as an important reminder: even well-conditioned athletes can experience significant muscle breakdown, and without pr

In the world of cycling, running, and triathlon, power meters have revolutionized training. No longer do athletes rely solely on feel, heart rate, or speed—objective wattage data provides a precise window into performance. At the heart of this data-driven approach lies Functional Threshold Power (FTP), a cornerstone metric for setting training zones, structuring sessions, and tracking progress. This article explores what FTP truly means, how to determine it accurately, its

Breast cancer remains one of the most common cancers affecting women and a leading cause of cancer death. In the United States, roughly 1 in 8 women will develop invasive breast cancer in their lifetime, and approximately 42,000 women die from the disease each year. Yet screening is highly effective: women who screen regularly are 25–42% less likely to die from breast cancer than those who do not. Cancers detected through screening are typically smaller, diagnosed at earlier

Imagine training your body to thrive in low-oxygen environments, not by moving to the mountains, but through carefully calibrated sessions that harness hypoxia as a therapeutic and performance tool. Intermittent hypoxia (IH), or hypoxia conditioning, is gaining traction as a non-pharmacological intervention for health optimization and athletic enhancement. Unlike the chronic, uncontrolled hypoxia of obstructive sleep apnea, which often leads to maladaptation, controlled moder

Week 4 of Inflammation Month Throughout this series, we’ve explored inflammation’s mechanisms, its impact on athletes, and its systemic effects. In this final installment, we focus on actionable, evidence-based strategies to manage inflammation through diet, supplements, and daily habits. These approaches not only support recovery and performance but also promote metabolic health, hormonal balance, and longevity. Foundations of an Anti-Inflammatory Diet The most robust evid

Week 3 of Inflammation Month While many endurance athletes first notice inflammation through sore muscles or joint issues, its effects extend far beyond the musculoskeletal system. Chronic or dysregulated inflammation can quietly disrupt hormones, metabolism, blood glucose control, gut health, and brain function, factors that influence not only performance but also long-term health and longevity. This article explores these systemic impacts, supported by research, and emphasi

Week 2 of Inflammation Month Endurance athletes push their bodies to remarkable limits through high-volume training and competition. While this delivers impressive adaptations, it also creates a complex relationship with inflammation, particularly in the musculoskeletal system. This article examines whether endurance athletes face heightened inflammation risks, how it influences training and performance, the concept of “good” inflammation, and targeted strategies for manageme

Week 1 of Inflammation Month Inflammation is one of the most fundamental processes in human physiology—essential for survival yet potentially harmful when dysregulated. For the average person navigating daily life, understanding inflammation is key to managing minor aches, supporting long-term health, and preventing chronic conditions. This article explores what inflammation is, its underlying mechanisms, the differences between acute/local and chronic/systemic forms, its imp

In the world of endurance sports, athletes and coaches are constantly searching for legal, evidence-based edges to improve performance, accelerate recovery, and support consistent training. While synthetic supplements often dominate discussions, whole-food-derived options like beetroot (beets), tart cherries, and broccoli sprouts have gained significant traction. These “super veggies” provide bioactive compounds, nitrates, polyphenols/anthocyanins, and isothiocyanates/sulfora

Knee osteoarthritis (OA) is one of the most common joint conditions affecting active adults, often impacting runners, cyclists, and other endurance athletes who rely on consistent training. While there is no cure, a multifaceted approach combining lifestyle strategies, conventional symptom relief, and targeted herbal supplements like Curcuma longa (turmeric/curcumin) and Boswellia serrata can help manage pain, stiffness, and function effectively. A recent 2025 systematic revi

Endurance athletes live in a world where pain is a constant companion. From the burning sensation in your quads during a hard interval session to the deep fatigue that settles in during the latter stages of a marathon or Ironman, discomfort is woven into the fabric of training and racing. Yet not all pain is created equal. Distinguishing "good" pain, the kind that signals adaptation and growth, from "bad" pain, which may indicate injury or overtraining, is one of the most cri

Lactate threshold (LT) testing has gained significant popularity among endurance athletes, from recreational runners and cyclists to elite competitors. By providing objective insights into metabolic responses, it enables more precise training zone prescription, helping busy athletes train efficiently without wasting time on suboptimal efforts. This article explores the science of lactate, debunks common myths, outlines testing methods, and details practical applications for i

In the world of endurance training, whether you're logging miles on the road as a runner, pushing watts on the bike, or grinding through triathlon sessions, pre-workout nutrition is often the difference between a strong, sustainable effort and hitting the wall prematurely. While many athletes obsess over intra-workout fueling or recovery shakes, the meal (or snack) you eat before training plays a critical role in performance, adaptation, and long-term gains. Recent research

In the world of endurance sports, data can be both a powerful ally and a potential distraction. Wearable technology provides an unprecedented stream of insights, but success lies in focusing on the metrics that truly drive adaptation, recovery, and performance. At Project Blue, we emphasize evidence-based monitoring to help athletes and active individuals train smarter, recover better, and minimize injury risk while pursuing their goals. Whether you are a competitive runner

Cardiovascular disease remains the #1 killer of adults in the United States. For endurance athletes who train hard and live long, the risk of atherosclerotic cardiovascular disease (ASCVD) is real — even if you feel invincible on the bike or run. The good news? We now have clearer, earlier guidance on how to lower that risk. In March 2026, major new cardiovascular guidelines were released by the American College of Cardiology, American Heart Association, and nearly a dozen ot

Endurance exercise is one of the most powerful tools for cardiovascular health. It improves fitness, reduces traditional risk factors, and enhances longevity. Yet emerging research reveals a nuanced reality: extreme volumes of endurance training can induce cardiac remodeling that, while often adaptive, may carry potential long-term risks, particularly in master athletes (typically age 40+). This “Cardiac Paradox” sits at the heart of modern sports cardiology. At Project Blu
