Unlocking the Power of Sleep: Fitness, Brain Health & Weight Management Insights

The NASM-CPT Podcast With Rick Richey

In this episode of the “NASM CPT Podcast,” host Rick Richey takes a deep dive into the critical role of sleep in overall health, wellness, and fitness performance. Inspired by his recent study of the Certified Wellness Coach certification and a lively text exchange with his family, Rick uncovers why sleep might be the most underrated element in reaching fitness goals. He debunks the myth that functioning on little sleep is a badge of honor and shares National Sleep Foundation guidelines for optimal sleep across age groups.

Rick explores how sleep impacts vital processes such as brain cleaning through the glymphatic system, memory consolidation (both declarative and procedural), weight management, and muscle growth. Backed by research, he details how lack of sleep can lead to weight gain by disrupting hormones like leptin and ghrelin, increase hunger, reduce insulin sensitivity, and even hinder muscle recovery due to lower testosterone, growth hormone, and IGF-1 levels.

Listeners will also get practical sleep hygiene strategies—from limiting caffeine and minimizing nighttime light exposure to implementing effective bedtime routines. Rick even explores the power of napping and when it can boost memory or aid in recovery after a rough night’s sleep.
