A New Study: Squats vs Leg Extension
(For Quad Growth)
Zabaleta-Korta (2021), The role of exercise selection in regional Muscle Hypertrophy: A randomized controlled trial, J Sports Sci.
The quadriceps is one of the biggest muscles in your body. It is one of your most important muscles in sports, and you cannot build a strong and impressive physique without them.
In a new 2021 study, 21 young men with strength training experience trained their respective exercise three times per week, doing four sets of twelve reps to muscular failure each workout.
Before and after the five weeks of training, the researchers used ultrasound to measure the cross-sectional area of the participants’ rectus femoris and vastus lateralis.
The study showed that the leg extension lead to significant more gains in the quads especially in the Rectus Femoris.
