Do you guys utilize the same technique barbell squatting as SLED hack squatting? The reason I ask is because hack squatting is basically barbell squatting turned 45 degrees.
Usually, on the eccentric portion of the hack squat, I just shove my knees out during the whole downward movement until my hips reach bottom. But when this happens, as Rippetoe puts it, "the lifter lets his knees move forward at the bottom of the squat.....he has relaxed his hamstrings, because they pull the knee back."
And since the hamstring should act as dynamic stabilizers, am I short-circuting my hamstring out of the movement?
Rippetoe recommends to move the knee forward in the first 1/3- 1/2 of descent and the rest of the movement consist of hips moving back during barbell squats. So would you guys recommend applying the same barbell squat technique on sled hack squats?
