Rest a ball between your back and a wall, and then squat until your knees get as close to 90 degrees as you can get, and then hold, working your way up to one minutes.
The more flexible you are, the more you will be able to get to 90 degrees. Overall, it is not as easy as it may look. Start out slow. This exercise is also a good way to help support your back, as you can lean back against the ball while doing this.
