Hold two dumbbells or kettlebells in the “rack position” (chest height under the chin). Take a slightly wider-than-shoulder-width foot position with your toes pointed out a bit. Upon descent, keep your chest up, abs braced, and push your butt back as you think about “opening your knees.” Keep your head in a neutral position (eyes looking forward) throughout the movement. Squat down as low as you can without creating excessive lumbar flexion, then return to the starting position by driving your hips through into extension and standing up tall. Keep the weights tight to the body while performing the exercise.
