NASM FNS study guide
NASM FNS · Work through your exam, one topic at a time.
The NASM Fitness Nutrition Specialist (FNS) is a nutrition-focused credential intended for fitness professionals who want to add evidence-based nutrition coaching to their training practice. Candidates typically come from personal training, group fitness, wellness coaching, or strength and conditioning backgrounds and want to help clients with eating behaviors, body composition goals, and long-term lifestyle change without practicing clinical dietetics. Because NASM's public course catalog lists its nutrition offering as the Certified Nutrition Coach (CNC), candidates researching the FNS should confirm the current product name, exam blueprint, and policies directly with NASM before enrolling or scheduling. Nutrition content in NASM's wellness pathway emphasizes food's impact on health, working through common nutrition myths, flexible eating styles, and evaluating supplementation for long-term health, all delivered through behavior-change coaching rather than rigid meal plans. The NASM FNS study guide has 6 sections and about 1,609 words.
