From using a support to a free Headstand (Sirsasana)
HEADSTAND requires core and upper body strength. We also need flexible/strong hamstrings and hip flexors to either lift up with bent knees, by kicking up, or by lifting with both straight legs. Spacial awareness will also help!
You would want to feel strong and sturdy in the preparation poses such as Down Dog, Plank on Forearms, Plank variations, Boat, Forearm Balance etc... Mastery of the Shoulderstand (Sarvangasana) and its variations is a prerequisite.
Headstand is not for everyone and they are alternative poses that you can do instead (ask your teacher).
