This updated American College of Sports Medicine position stand analyzed 137 systematic reviews (30,000+ participants) to determine what actually matters in resistance training.
The big takeaway: resistance training works—really well—no matter how you do it (as long as you do it).
It significantly improves strength, muscle size, power, endurance, and overall physical function like balance and gait speed.
A few key principles actually move the needle:
* Strength gains: heavier loads (≥80% 1RM), full range of motion, 2–3 sets, ≥2x/week
* Hypertrophy: higher total volume (≈10+ sets/week), eccentric loading
* Power: moderate loads (30–70% 1RM), fast intent, explosive lifts
* Consistency > complexity: almost any program beats doing nothing
TLDR:
Lift heavy sometimes. Move fast sometimes. Get enough volume. And do it consistently.
Stop chasing perfect. Start chasing progress.
Save this if you needed the reminder—and send it to someone stuck in program-hopping mode.
