Lunge to Squat Form Cue
For this exercise, you aren’t rising in between switching – keep your body LOW and knees bent the entire time. Torso stays upright, step back into your lunge, then keep the front knee bent as you step out to the side to squat. Step the opposite foot behind and lunge. Watch the front knees to make sure they don’t extend past the toes.
