Common mistakes
Feet directly under the bar, forcing a forward knee and heel lift
Move the feet a few inches forward so you stay balanced over mid-foot.
Leaning on the bar instead of bracing
Brace your core as you would on a free squat.
Forgetting to set the safety stops
Set them before every session to just below your lowest point.

From standing to thighs at or below parallel, keeping heels down and spine neutral.
