The Claim
Can leg presses make you stronger and build muscle in trained men?
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.
If you do leg presses for 9 weeks, your legs will get stronger and bigger—even if you do it once or three times a week.
See the scientific wording
In trained men, resistance training using unilateral leg press 45° for 9 weeks significantly increases maximal strength (1RM) and quadriceps cross-sectional area (CSA), regardless of training frequency, indicating that the exercise and duration are sufficient to drive adaptation.
What the research says
1 studyThe study found that doing the leg press once or three times a week for 9 weeks both made trained men stronger and built more quad muscle — so how often you do it doesn’t matter as long as you do the exercise long enough.
