Take a wide stand with your feet. Hips and shoulder square, back neutral.
Squat to one side, by flexing that knee and hinging at the hips.
The heel stays down, keep your torso upright, and assisting leg straight.
Descend as low as you feel comfortable, staying tight, and not going into posterior pelvic tilt (Don’t let your pelvis tuck at the bottom)
Drive through the heel, extending the knee and hip to return to the start.
Hips fully extending at the top, squeezing the glutes, and switch sides.
Repeat for repetitions.
