The Claim

Does training with full range of motion help all muscles grow better?

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

Whether you're working your quads, calves, or biceps, stretching them fully during exercises helps them grow bigger — this works for many different muscles, not just one.

See the scientific wording

Resistance training performed at longer muscle lengths enhances hypertrophy across multiple muscle groups including the vastus lateralis, rectus femoris, vastus medialis, vastus intermedius, gastrocnemius, and biceps brachii, indicating that the effect is not isolated to a single muscle but is a generalizable phenomenon.

What the research says

1 study

  1. Study: Muscle hypertrophy from partial repetition at long vs. short muscle length: A systematic review and meta-analysis

    This study found that lifting weights when your muscles are stretched out (longer length) makes them grow bigger across many different muscles—not just one—so the idea that this works for lots of muscles is backed up.
