AD #186 - Fueling Peak Performance w/ Erik Grohmann
from Iron Sights · host Iron Sights
Welcome back to another After Dark episode here on the Iron Sights Podcast. Tonight, I’m hanging out with Erik Grohmann, a former U.S. Marine infantryman who found his passion for fitness and nutrition while serving and then went on to earn a master’s in nutrition and dietetics. These days Erik is the nutrition coach over at Modern Athlete Strength Systems, where he works with law enforcement, firefighters, EMS, military members—and really anyone who wants to perform at a higher level.We get into the fundamentals of human performance: the common nutrition mistakes people keep making, what actually works versus the trendy quick fixes, and the practical steps you can take to start seeing results right now. Eric also talks about how his Marine Corps background shaped his no-nonsense approach and why he launched Grunt Grubb to help clients cut through the noise. If you’re tired of diet confusion and ready for straight talk that actually delivers, you’ll want to stick around for this one.Timestamps:00:00 Intro05:59 Marines to Nutrition11:25 Dietetics Career15:14 Launching Modern Athlete19:15 Coaching Hurdles36:28 Common Issues51:38 Fitness Goals53:48 Calories & Macros56:42 Fiber & Micros58:43 Long-Term Habits01:04:41 Carbs & Performance01:25:32 Field Tips01:38:23 Meal Planning01:43:00 Personalized Coaching02:03:45 Modern Athlete ServicesRed Dot Fitness Training Programs:rdfprograms.comOnline Membership (Full Access To All Programs & Virtual Coaching):https://www.reddotfitness.net/online-membershipVirtual Coaching:https://www.reddotfitness.net/virtual-coachingSelf-Guided Programs:https://www.reddotfitness.net/Self-Guided-Programs1Connect With Us:Website - https://ironsightspodcast.com/Instagram - https://www.instagram.com/ironsightspodcast/Facebook - https://www.facebook.com/
