The Claim

Based on systematic review evidence, training to momentary muscle fatigue, equipment type (free weights vs. machines), exercise complexity, set structure, time under tension, blood flow restriction, and periodization do not consistently show additional benefits for strength, hypertrophy, or power outcomes in resistance training for healthy adults.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Supports
26score
Challenges
0score

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Description
1 study reviewed
In plain English

Different ways of lifting weights, like using machines or free weights, or changing how you do your sets, don't always make you stronger or bigger than basic training, according to big reviews of studies.

Training to momentary muscle fatigue, equipment type (free weights vs. machines), exercise complexity, set structure, time under tension, blood flow restriction, and periodization do not consistently show additional benefits for strength, hypertrophy, or power outcomes in resistance training for healthy adults, based on systematic review evidence.

What the research says

1 study
  1. Study: American College of Sports Medicine Position Stand. Resistance Training Prescription for Muscle Function, Hypertrophy, and Physical Performance in Healthy Adults: An Overview of Reviews

    The study looked at the same training methods as the claim and found they don't always help with getting stronger or bigger muscles, just like the claim says.
