EPISODE DESCRIPTION How many hard sets does muscle actually need, and does the weight on the bar matter? In part two of the training series, Dr. Altamash Raja and Dr. Darsh Shah work through the 2026 ACSM position stand: strength and size as two goals with two prescriptions, why effort matters more than load for growth, and how little it takes to maintain what you've built. They audit their own programs live, then make the case for building a training floor around your real constraints before adding anything. TOPICS COVERED Strength vs. hypertrophy: two goals, two prescriptions, and why you need to know which one you're chasing What the 2026 ACSM position stand asks for: heavy loads for strength, at least 10 hard sets per muscle per week for size, effort over load Progressive overload, momentary failure vs. 2–3 reps in reserve, and correcting the "80% = RPE 8" slip from part one A live audit of both hosts' programs with fractional set counting, plus the Nordic hamstring evidence debate The maintenance dose: keeping strength and size on as little as one session a week, and what older adults need Allostatic load, rest intervals, full-body vs. split training, and why you build the floor first, then add RESOURCES & LINKS MENTIONED Studies Currier et al., ACSM Position Stand on Resistance Training Prescription, Med Sci Sports Exerc (2026) (https://doi.org/10.1249/MSS.0000000000003897) Pelland et al., The Resistance Training Dose Response, Sports Medicine (2026) (https://link.springer.com/article/10.1007/s40279-025-02344-w) van Dyk et al., Nordic hamstring exercise halves the rate of hamstring injuries, BJSM (2019) (https://www.mendeley.com/catalogue/3a292a92-fca1-3d9b-9fb2-654d278d38b9/) Impellizzeri et al., Reappraisal: Nordic hamstring effect inconclusive, J Clin Epidemiol (2021) (https://www.semanticscholar.org/paper/8938af53d1760cb9d5aa328dc663059bdd9f7ff5) Spiering et al., The minimal dose of exercise to preserve endurance and strength, J Strength Cond Res (2021) (https://pubmed.ncbi.nlm.nih.gov/33629972/) Singer et al., Inter-set rest intervals and muscle hypertrophy, Front Sports Act Living (2024) (https://www.frontiersin.org/journals/sports-and-active-living/articles/10.3389/fspor.2024.1429789/full) Zhang et al., Resistance training volume and mortality, BJSM (2026) (https://doi.org/10.1136/bjsports-2025-110503) McEwen and Stellar, Stress and the individual, Arch Intern Med (1993) (https://pubmed.ncbi.nlm.nih.gov/8379800/) Concepts & tools Progressive overload (https://en.wikipedia.org/wiki/Progressive_overload) · One-repetition maximum (https://en.wikipedia.org/wiki/One-repetition_maximum) · RPE (https://en.wikipedia.org/wiki/Rating_of_perceived_exertion) Allostatic load (https://en.wikipedia.org/wiki/Allostatic_load) · DOMS (https://en.wikipedia.org/wiki/Delayed_onset_muscle_soreness) · Nordic hamstring curl (https://www.physio-pedia.com/Nordic_Hamstring_Training) On-air corrections Allostatic load was coined by McEwen and Stellar in 1993, not the 1930s or 40s. In Zhang 2026, the lowest mortality was in people combining resistance training with aerobic activity. These are observational cohort data.
