The 2026 ACSM position stand synthesizes 137 systematic reviews representing more than 30,000 participants. Its central practical message is that regular resistance training matters more than chasing unnecessary program complexity, while load, volume and intent should still be matched to the specific outcome.

Title: Resistance Training Prescription for Muscle Function, Hypertrophy, and Physical Performance in Healthy Adults: An Overview of Reviews.

Design & population
This was an overview of reviews used to update ACSM's prior resistance-training guidance. ACSM reports that the synthesis incorporated 137 systematic reviews and data from more than 30,000 participants, covering strength, hypertrophy, power, muscular endurance, contraction velocity and physical function in healthy adults.
Key findings
- Moving from no resistance training to consistent resistance training produces the largest practical gain for most adults.
- Training all major muscle groups at least twice per week is emphasized as a broadly useful target.
- Heavier loads are generally favored when maximizing strength is the priority.
- Higher weekly volume is relevant for hypertrophy; ACSM's public summary highlights approximately 10 sets per muscle group per week as a practical benchmark.
- Many modalities can work, including free weights, machines, elastic resistance, bodyweight and home-based training.
- Advanced methods such as mandatory training to failure, complex periodization or a specific equipment type are not universally required for meaningful outcomes.
What it does not prove
This guidance is aimed primarily at healthy adults and should not be read as a sport-specific prescription for advanced athletes. An umbrella review also inherits limitations from the systematic reviews it includes, including heterogeneity in training status, program design, outcome measurement and study quality.
Coaching application
For general clients, adherence, progressive loading and enough weekly work should take priority over novelty. For advanced physique or strength athletes, specificity still matters: exercise selection, weekly volume distribution, proximity to failure, fatigue management and progression need to be individualized beyond general-population guidance.
