If you can’t do barbell squats, or squats
with a bar across your back, you can do dumbbell squats to get similar results.
Just remember to come down as deep as you can or until you touch the
dumbbells to the floor. Make sure you keep your head up, and you want to focus
on bending your knees more. You want to get your butt down as low as you
can, and you only want to bend your back slightly.
