Wearables Provide Useful Data but Accuracy Still Varies
Wearable fitness technology has expanded rapidly, giving consumers access to real-time data about steps, sleep, heart rate and activity levels. While these tools can support motivation and awareness, researchers caution…
Exercise Timing May Influence Metabolic Health
Researchers are increasingly exploring how the timing of exercise interacts with circadian rhythms. Some evidence suggests physical activity performed later in the day may improve blood glucose regulation and metabolic…
Exercise May Shape the Gut Microbiome
Emerging research suggests regular physical activity may influence the composition and function of the gut microbiome. Studies comparing athletes with sedentary individuals have found differences in microbial diversity and metabolic…
Muscle Quality May Be as Important as Muscle Size
Researchers are increasingly examining muscle quality; the strength and function of muscle relative to its size, as a key factor in physical performance and healthy aging. Studies suggest muscle quality…
Cardiorespiratory Fitness Remains One of the Strongest Health Predictors
Cardiorespiratory fitness, often measured through VO₂ max, continues to emerge as one of the most powerful indicators of long-term health. Numerous studies show that individuals with higher aerobic fitness levels…
Hybrid Work May Be Reducing Daily Movement
The shift toward hybrid and remote work is reshaping how people accumulate daily physical activity. Recent research suggests individuals take significantly fewer steps on days they work from home compared…
Sitting Too Long May Still Harm Health – Even if You Exercise
Meeting recommended exercise guidelines does not fully offset the health risks of prolonged sedentary behavior. A growing body of research indicates that extended periods of sitting can independently increase the…
Exercise “Snacks” Continue to Gain Scientific Support
Short bouts of movement spread throughout the day are gaining credibility as a practical way to improve health. Researchers are increasingly studying “exercise snacks” – brief bursts of activity lasting…
Smarter Carbs: The Shift to Low-Glycemic, High-Fiber Choices
Carbohydrates are no longer the enemy—but the type of carbs you choose matters more than ever. A growing nutrition trend is the shift toward low-glycemic, high-fiber carbohydrate sources like lentils,…
Recipe of the Month: Lemon Herb Chicken & Quinoa Spring Power Bowls
This Lemon Herb Chicken & Quinoa Spring Power Bowl is designed for sustained energy and convenience; two priorities for anyone balancing fitness, work, and nutrition. Built around low-glycemic carbohydrates like…
Fit Tech in 2026: What Works, What Doesn’t, and Who It Serves
Technology is no longer an emerging trend in fitness. It is infrastructure. Most clients already use some form of fitness technology—smart watches, sleep trackers, training apps, virtual platforms. Many arrive…
Scope of Fuel: Coaching Nutrition Without Crossing the Line
In the age of Ozempic and Influencers, the most valuable tool in your kit isn’t a meal plan—it’s your scope of practice. Mike Fantigrassi, Head of Product, NASM It usually…
Fueling for Participation
Fitness professionals frequently encounter a familiar pattern. A client begins an exercise program with enthusiasm, trains consistently for several weeks, then gradually reports fatigue, persistent soreness, irritability, or declining motivation….
Protein Distribution vs. Total Intake
Debate continues regarding whether evenly distributing protein across meals improves muscle protein synthesis compared to consuming the majority at one sitting. Recent controlled trials indicate that while total daily protein…
Ultra-Processed Foods and Mental Health Associations
Emerging nutritional epidemiology continues to explore the relationship between ultra-processed food intake and mental health outcomes. Recent systematic reviews report associations between higher consumption of ultra-processed foods and increased risk…
Creatine in Women: Expanding the Evidence Base
Once viewed primarily as a strength supplement for male athletes, creatine is now being studied more extensively in women across the lifespan. Recent trials suggest potential benefits beyond muscle performance,…
Energy Availability Beyond Elite Athletes
Low energy availability has long been studied in elite endurance athletes, but recent research suggests the concept extends well beyond high-performance sport. Recreational exercisers, particularly women balancing training, work, and…
Ultra-Processed Foods: Dose, Context, and Pattern
Ultra-processed food consumption continues to be associated with elevated cardiometabolic risk in large population studies. However, emerging analyses highlight dose-response relationships rather than binary categorization. Moderate inclusion within otherwise nutrient-dense…
Creatine Beyond Muscle Performance
Creatine supplementation research has expanded beyond strength and power metrics. Recent studies suggest potential roles in cognitive performance under sleep deprivation, bone mineral density support when paired with resistance training,…
Sodium Intake in Active Populations
General sodium reduction guidance remains appropriate for sedentary and hypertensive populations. However, emerging research suggests highly active individuals—particularly endurance athletes in hot environments—may require individualized sodium strategies to maintain hydration…
