The Claim

Progressively increasing weekly resistance training volume beyond 22 sets per muscle group enhances strength gains without significantly increasing muscle hypertrophy.

What the research says

Supports is higher

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

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
2 studies reviewed
In plain English

When weekly resistance training exceeds 22 sets per muscle group, strength increases further without a meaningful increase in muscle size.

See the scientific wording

Progressively increasing weekly resistance training volume beyond 22 sets per muscle group enhances strength gains without significantly increasing muscle hypertrophy.

Why this might work

When muscles are trained with very high volumes, the nervous system gets better at recruiting more muscle fibers and firing them faster, which makes the person stronger without needing the muscles to grow bigger.

What the research says

2 studies
  1. Study: Effects of Different Weekly Set Progressions on Muscular Adaptations in Trained Males: Is There a Dose–Response Effect?

    This study found that doing more sets of squats each week made people stronger, but didn’t make their thighs noticeably bigger — just like the claim says. More work = more strength, but not much more muscle size.

  2. Study: Does increasing the resistance-training volume lead to greater gains? The effects of weekly set progressions on muscular adaptations in females

    When people did more than 22 sets of leg exercises per week, they got stronger without their muscles getting noticeably bigger overall — just a little bigger in one spot. So more sets help strength without making you bulk up much.
