In discussing deep squatting compared to half and quarter squats the literature advises technique be acquired with expert supervision for it to be an effective training tool. When this occurs the risk of degenerative changes due to an increased motion and possible deterioration due to mechanical influences is unfounded.
The Pendulum Squat Pro requires little supervision, has range limiters and assures the athlete is using a technique based upon his or her limb lengths and body biomechanics that with a barbell even the most expert coach could not acquire. With the floating shoulder yoke the athlete can apply maximum musculature force at any depth not needing to worry about joint discomfort or adjusting form.
