Stand with your feet slightly wider than hip-width apart and toes pointed slightly outward. Raise the weight overhead. If you don't have access to a barbell, you can hold two dumbbells instead.
Sit back into your squat, bending your knees to 90 degrees while keeping your elbows straight. If this is too difficult, rest the weight in front of the chest and do a front squat instead, or skip the weight altogether.
Straighten your legs to standing to complete one rep.
