Bodyweight Squat

Overview

The bodyweight squat is a fundamental movement assessment that evaluates an athlete’s ability to perform a basic squatting motion with proper form and range of motion. This movement is commonly used in athletic assessment and training as it provides valuable information about lower extremity mobility, strength, and movement patterns.
