The American College of Sports Medicine just updated its resistance training guidance for the first time since 2009 — and after reviewing more evidence than ever before, its central finding is refreshingly unglamorous.
The most comprehensive review of its kind
The 2026 ACSM position stand synthesized 137 systematic reviews covering more than 30,000 participants, led by Currier and colleagues at McMaster University. It's the largest evidence base ever assembled on resistance training prescription, and the first major update to ACSM's guidance in 17 years (Currier et al., 2026).
The biggest predictor of results isn’t the plan — it’s showing up
The headline finding is that the single largest jump in outcomes comes from moving from no resistance training to any resistance training at all — not from optimizing an already-good program. That matters because an estimated 60% of adults currently do no structured strength work, well below the twice-weekly minimum the guidelines recommend (Currier et al., 2026; ACSM, 2026).
You don’t need to train to failure
The updated evidence base found that training to absolute momentary failure isn't necessary for most healthy adults to see results. Stopping a set two to three reps short of failure produces comparable strength and hypertrophy outcomes with meaningfully less fatigue (Currier et al., 2026).
Different goals call for different prescriptions
The guidelines break recommendations out by goal. For strength, they point to loads around 80% or more of one-rep max, 2–3 sets per exercise performed early in a session, at least twice weekly, through a full range of motion. For hypertrophy, total weekly volume is the main driver — at least 10 sets per muscle group per week — and loads anywhere from 30–100% of max work as long as sets are taken close to effort. For power, lighter loads (30–70% of max) moved as fast as good form allows are recommended (Currier et al., 2026).
Equipment matters less than people think
The update explicitly validates resistance bands, bodyweight training, and home-based programs as legitimate ways to produce the strength and functional gains described in the guidelines — a meaningful shift from more gym-centric guidance of the past (Currier et al., 2026).
A quick note
This article is educational, not medical advice. Finish Line Personal Training is a strength & conditioning coaching company, not a medical provider. If you have an existing injury or health condition, talk to your doctor before starting or changing a resistance training program. If you're medically cleared to exercise, we're glad to help you apply these guidelines to your own program.
