Proper Technique in the Execution of a Barbell Back Squat: A review.

Jeremy G Carter, Kelly A Brooks


The barbell back squat can increase muscular strength, power, and endurance for the lower body depending on how the intensity, repetition scheme, rest periods, and execution of the movement is modified. The BBS is one of the most popular and studied exercises in the health and fitness world. Though this is one of the most popular and utilized exercise, there are arguments on the proper technique, depth, and internal/ external forces for the BBS. Exercises that employ the squatting motion are often employed for the strength and conditioning of athletes. However, the benefits of squatting are not limited to the competitive athlete, but can be used in the general population, as well as rehabilitation settings. The purpose of this review of literature is to increase the reader’s knowledge on this popular exercise. By reading this review of literature, the reader will learn how to efficiently and safely execute the squat.
