Stand with feet close together (hip-width or slightly narrower) and toes pointing forward. Brace your core, push your hips back slightly, and bend your knees to lower your body into a squat while keeping your torso upright. Go as deep as comfortable, then push through your feet to stand back up, maintaining balance and control throughout.
Log your bodyweight narrow stance squat sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
