While in this forward bend, I like to do a few variations to bring myself deeper in to the pose. You can try taking a yogi toe lock with your fingers hooked around your big toes to deepen your forward fold. If that's easy, try slipping your upturned palms under your feet. Another good one is to bend the knees and bring the palms flat next to your feet. Then work on straightening the legs while keeping the palms flat. Make sure you are bringing weight into the balls of your feet so that your hips stay directly over your ankles. When you do this pose at home, you can take as much time as you want to hang out, a chance you don't often get in a class.
Complete the half sun salutation by coming back through raised arms into mountain pose. Do five or more half sun salutations.
