Sumo squat progression

From easiest to hardest. Move to the next step when you can do the current one with good form.

1. Sumo squat · Beginner · reps
   A wide-stance squat with the toes turned out: the hips sit straight down between the feet with the knees pushed out over the toes until the thighs are parallel to the floor, torso upright, then you stand back up.
2. Side lunge · Intermediate · reps
   From standing, one foot takes a wide step out to the side and the hips sit back and down over that bent leg while the other leg stays straight with its foot planted; then push off to bring the feet back together.
