What stretches should I do to do a Malasana? My heels won’t touch the ground.

The key here is building enough core strength to keep your spine upright while squatting. Think of your belly button pulling back to your spine, and the crown of your head reaching up to the ceiling. This upward imagery and alignment will help you get down into this low position with control.

Also, use props under your seat to gradually make your way closer to the floor each week.
