From standing still position dive down to be able to push your body up using your hands.
Using strength of your back and core, move your legs up to get your body completely straight and in vertical position with your head pointing to the ground.
With a slow and controlled movement, start moving your body down to the ground while still holding it on arms. You should move yourself down till you are parallel to the ground.
You shouldn't be touching the ground with your feet - just holding on your arms.
Then move back to the starting position.
