This exercise is a variation on the classic kneeling side kick
To do this exercise you will need a mat. Start by kneeling and then lean over to place one hand on the ground. Allow the opposite leg to float up into the air. Inhale into the back of the ribs and then exhale as you bend the floating knee and then straighten it higher into the air. Inhale as you lower it back to hip level and then exhale hip height. Repeat 8-10 times.
Things to think about
Make sure that your hip is right over your bottom knee and the your shoulder is directly above the wrist. This will create the longest possible spine.
If this exercise is too much for the wrist you can make a fist with your hand to protect the wrist
