Tripod Headstand

When practicing for the first few times you may want to do this against a wall for support, or in the corner of 2 walls for extra support. Do this on a yoga mat or folded blanket, but not too much padding. You'll need to remain centered on your head and not tip to the side. Make sure to tuck your shirt in if needed, to prevent it from falling in your face and restricting your breathing.
Begin on your hands and knees, keeping your hands at shoulder distance apart. Place the top of your head on the floor. You will essentially form a triangle from your hands to your head at the apex. Keep arms bent at 90 degree angle with palms flat on the floor, elbows over wrists and in line with your shoulders. Keep your neck long. Do not allow your shoulders to sag to your ears. Engage your core (abs).
Lift your hips and knees so you are on your toes, carefully walk your feet towards your hands until your knees can be placed on your triceps. Lift your feet to match the illustration above, then press your big toes together. Remain here as long as is comfortable.
To exit: bring your feet down, then bring your head up. Remain in child's pose for a few moments to allow your blood to circulate properly (preventing headrush).
Full extension of the above pose: From the above (as shown in the illustration), bring your heels towards your glutes, activate your core, activate your legs and extend them upwards. Keeping your core activated will stabilize your balance. Push down through your arms to take pressure off your neck, and prevent your shoulders from sagging to your ears.
To exit: bend your hips and knees, place knees back on triceps then bring your feet to the floor. Remain in child's pose for a few moments to allow your blood to circulate properly (preventing headrush).
Benefits: helps with cores strength, increases coordination, builds confidence simply by learning an inversion.
A good tip for learning headstands: Sit and/or walk with a heavy book balancing on your head. This will train your neck to be long, instead of tucking your chin or arching your neck; and you become used to the feeling of having pressure on your head.
