Why Does Your Genetics Determine Your Best Training Type?
Emma Sullivan and David Park break down how your genetic muscle fiber composition—whether you're naturally slow-twitch or fast-twitch dominant—shapes which types of exercise your body responds to best, and why knowing this matters far beyond gym performance. They explore what the research actually says about the ACTN3 gene, practical ways to identify your own fiber type without a muscle biopsy, and the counterintuitive longevity strategy of training your genetic weaknesses alongside your strengths. By the end, you'll understand why fighting your biology wastes effort, but ignoring it altogether costs you decades of health.Follow The Wellness Rhythm Show: ▶️ YouTube: https://www.youtube.com/@TheWellnessRhythmShow 📖 Newsletter: https://thewellnessrhythmshow.substack.com Powered by VoxCrea.AI
