The Claim
In the lower body, the hypertrophic response to range of motion is muscle-specific, with the adductors and gluteus maximus exhibiting greater muscle growth under full range of motion compared to limited range of motion, while the vastus lateralis and rectus femoris show no significant difference in growth between full and limited range of motion conditions, indicating that muscle hypertrophy does not respond uniformly to range of motion manipulation.
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.
When you do full-range exercises like deep squats, some leg muscles like your inner thighs and butt grow more than others, but your front thigh muscles don’t seem to care whether you go deep or not — not all muscles react the same way to how far you move.
See the scientific wording
The hypertrophic response to range of motion is muscle-specific in the lower body, with adductors and gluteus maximus showing greater growth with full ROM, while vastus lateralis and rectus femoris show no significant difference, indicating that not all muscles respond uniformly to ROM manipulation.
What the research says
1 studyThis study looked at whether doing exercises through a full range of motion makes muscles grow more than doing them through a partial range — and found that in the legs, some muscles might grow better with full movement, while others don’t change much. That matches the claim.
