Also, don't sit. You should lower yourself supported by muscle, don't relax and sit. It is very hard to push yourself back up once you have relaxed into "sit". Use muscle and keep them active for support.. Keep your weight centred, spine straight and don't lean forward in an attempt to pull yourself back up. Only go as low as you can maintain good technique. be patient and you will get there, provided you don't have any knee issues that prevent you from doing level changes.

Squats are very useful to strengthen but the best training for level changes has been in my experience to practice level changes. ;) Hope this helps!
