Will squatting past parallel increase muscle size more than squatting to 90 degrees? Relationship between hypertrophy (increase in muscle size) and range of motion.
You've been in the gym where the person next to you is completing half reps of a bicep curl or squat and you wonder, is that helping or hurting? First and fore-most I typically recommend working through a full and available range of motion for every movement. Personally I want to be strong through the entire range, regardless of how little or large of that range I'm using. However, when it comes to hypertrophy, or increase in muscle size, is there an optimal range of motion for each muscle group that favors enhancing muscle size? For example, will squatting past parallel produce a more favorable environment for muscle growth compared to squatting to 90 degrees? As we break down this article, we will see what the research has to say about specific muscle groups working through specific ranges of motion and how that may produce more or less enhancement in muscle size. Very interesting data to interpret with my final take on what to focus on as far as working through specific ranges of motion with your training.
