The Claim

Resistance training performed to volitional interruption, compared to training to muscle failure, results in similar increases in muscle strength, cross-sectional area, and pennation angle in untrained men, with no differential effect observed between high-intensity (80% 1RM) and low-intensity (30% 1RM) loads.

What the research says

Supports is higher

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

Supports

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.

Cause and effect
1 study reviewed
In plain English

For beginners, stopping resistance exercises just before your muscles give out works just as well as pushing to complete failure for building muscle strength and size, whether you're lifting heavy or light weights.

See the scientific wording

Resistance training performed to volitional interruption (stopping before muscle failure) causes similar increases in muscle strength, cross-sectional area, and pennation angle as training to muscle failure in untrained men, regardless of whether high-intensity (80% 1RM) or low-intensity (30% 1RM) loads are used.

What the research says

1 study
  1. Study: Effect of Resistance Training to Muscle Failure vs. Volitional Interruption at High- and Low-Intensities on Muscle Mass and Strength

    The study found that stopping exercise before complete exhaustion gives similar muscle gains as pushing to total failure, whether using heavy or light weights, in beginners.
