When Physiology Outpaces Behavior: Coaching Challenges in the Retatrutide Era
In Article 1 of this series, we explored how retatrutide may represent a significant shift in obesity pharmacotherapy rather than simply another iteration of GLP-1 receptor agonism. Through its combined targeting of GLP-1, GIP, and glucagon receptors, retatrutide appears capable of producing weight-loss reductions approaching the outcomes historically associated with bariatric surgery (Knerr et al., […]
The Retatrutide Era: Why Personal Trainers Must Prepare for the Next Evolution of Obesity Pharmacotherapy
Over the past several years, GLP-1 receptor agonists have fundamentally reshaped conversations surrounding obesity management, metabolic disease, and long-term health. Medications such as semaglutide and tirzepatide have introduced levels of weight-loss efficacy that, until recently, were difficult to achieve outside of bariatric surgery. However, retatrutide appears to represent something categorically different. Rather than simply improving […]
Stop Programming Workouts. Start Designing Outcomes: What the New ACSM Guidelines Really Mean for Personal Trainers
In Article 1 of this series, we established a clear hierarchy within the 2026 American College of Sports Medicine (ACSM) Position Stand. Load, volume, frequency, and range of motion emerged as the primary drivers of adaptation, while many other variables, despite their popularity, were shown to have far less consistent impact. In Article 2, we […]
Resistance Training as the Engine of Performance: What the 2026 ACSM Position Stand Means for Strength, Energy, and Real-World Function
In Article 1, we established a clear hierarchy within the 2026 American College of Sports Medicine (ACSM) Position Stand. Load, volume, frequency, and range of motion are the primary drivers of muscular fitness adaptation, while many other variables, despite their popularity, do not hold the same significance. This clarification is valuable in itself, but it […]
Beyond the Guidelines: What the 2026 ACSM Position Stand Gets Right—and What It Changes for Personal Trainers
The 2026 American College of Sports Medicine (ACSM) Position Stand on resistance training marks one of the most significant updates to training prescriptions in over a decade. Based on 137 systematic reviews and involving more than 30,000 participants, this document consolidates the current evidence regarding resistance training variables that influence muscle function, hypertrophy, strength, and […]
Why Nutrition Debates Feel So Personal: Cognitive Bias, Confirmation Bias, and the “Two Camps” Problem
If you’ve been coaching for any length of time, you’ve seen it play out in real time. Two clients read two “credible” sources. They walk in with two different conclusions. Both are certain. Neither is interested in nuance. At that point, you’re not really coaching nutrition behaviors. You’re coaching interpretation, and sometimes you’re coaching identity. That’s […]
Food as Medicine: What Personal Trainers Need to Know About the Movement Reshaping Preventive Healthcare
Every trainer has heard a version of the phrase “Food is medicine.” Sometimes it’s a thoughtful statement. Sometimes it’s a marketing hook. And sometimes it’s a client trying to make sense of conflicting advice after one too many late-night “wellness” rabbit holes. In Article 1 of this series, we focused on why adults often struggle […]
Nutrition Literacy in the Digital Age: Helping Clients Vet Online Health Information
Every trainer has seen it. A client walks in motivated, anxious, and armed with a brand-new nutrition “truth” they found online—something that promises fat loss, better hormones, better gut health, better sleep, better everything… by next Tuesday. At the heart of the matter lies the fact that the internet has absolutely expanded access to health […]
Protein Timing and Thresholds
For those engaged in health and performance, recent shifts in nutrition science reflect a long-awaited move toward more practical and evidence-based recommendations, particularly in the area of protein intake. Current evidence now supports adults aiming for 1.2–1.6 g/kg/day of protein, a meaningful increase from the long-standing benchmark of 0.8 g/kg/day. While this adjustment is certainly […]
New Year, Same Muscle: Why Strength Beats Willpower for Resolutions That Last – A Personal Opinion
Every January, millions of people hit the ground running with lofty health goals. Some chase steps. Others slash calories. Many count days, streaks, or weigh-ins. But what if the real secret to lasting change isn’t willpower at all? What if it’s strength? In my last two NFPT articles—Strength, Not Streaks: Resistance Training as the Real […]
