The magic power behind sit ups
How to do squats? Feet slightly wider than shoulder-width Toes rotated out slightly Think about sitting on your hips. In this way, hips will go back first before the knees could bend. And knees will bend less this way. Push hips back first (back will also go back slightly) then go down (and bend the knees). Lower back should not be stretched much, as people usually do while doing squats with bar. Keep your back straight or natural. You shouldn't feel your tail being pushed up. Pushing through the heal, you should feel your weight on your heel. Head and chest should be up. Lowering down, 90 degrees parallel to the ground. src: https://www.youtube.com/watch?v=otzWCWpuW-A&t=454s
