Evidence Standards
Our Evidence
Standards
Every plan draws from the same peer-reviewed literature used by professional sports teams, research hospitals, and university athletics programs.
💪
NSCA
National Strength and Conditioning Association. The gold standard for resistance training prescription, periodization models, and athlete testing protocols. All programming aligns with NSCA’s evidence-based guidelines.
🏥
ACSM
American College of Sports Medicine. The leading authority on exercise prescription for clinical populations. We follow ACSM guidelines for all medical athlete adaptations and cardiovascular exercise parameters.
🥗
ISSN
International Society of Sports Nutrition. Sets the evidence standard for supplement recommendations. Our Tier 1/Tier 2 classification system follows ISSN’s framework directly.
🩸
ADA
American Diabetes Association. All T2 Diabetes, blood sugar management, and insulin-related exercise adaptations follow ADA clinical practice standards, including medication interactions.
❤️
AHA
American Heart Association. Exercise intensity guidelines, blood pressure management, and cardiovascular risk stratification for all clients with hypertension or cardiac history.
🧪
Peer-Reviewed Literature
Beyond certifying bodies, we draw from published research in journals including Medicine & Science in Sports & Exercise, Journal of Strength and Conditioning Research, and the British Journal of Sports Medicine.
Supplement Classification
How We Classify Supplements
Modeled after the ISSN evidence classification. We only recommend Tier 1 and Tier 2.
✅ Tier 1 — We Recommend
Strong, consistent evidence from multiple RCTs. Safe and effective across diverse populations.
Examples: Creatine monohydrate, caffeine, beta-alanine, vitamin D, protein
✅ Tier 2 — We Recommend
Limited but promising evidence. Generally safe with some populations showing benefit.
Examples: Omega-3s, magnesium, zinc, ashwagandha, citrulline malate
✗ Tier 3+ — We Don’t
Little to no reliable evidence, or primarily industry-funded research. Not included regardless of popularity.
