The rectus femoris muscle exhibits greater hypertrophic adaptation to isolated knee extension exercises than to compound movements involving hip and knee flexion due to biomechanical limitations in force production during multi-joint movements.
What the Evidence Shows
We analyzed the available evidence and found that 54 studies or assertions support the idea that the rectus femoris muscle grows more in response to isolated knee extension exercises compared to compound movements that involve both hip and knee motion, likely because of how force is produced in...
