A handstand is the act of supporting the body in a stable, inverted vertical position by balancing on the hands. In a basic handstand the body is held straight with arms and legs fully extended, with hands placed approximately shoulder-width apart. There are many variations of the basic handstand, but in all cases a handstand performer must have good upper body strength and balance.
Handstands are performed in many athletic activities, including [freerunning], breakdance, acro dance, fitness competitions, circus acrobatics, cheerleading and Capoeira. In yoga, the handstand is known as Adho Mukha Vrksasana (downward-facing tree pose). Handstand dives are one of the main categories found in competitive platform diving. Some variation of the handstand is performed on every gymnastic apparatus, and many tumbling skills pass through a handstand position during their execution.
A standard straight-back style handstand consists of five key points of posture.
Some handstand variations, or handstands utilizing apparatus, will require a break from these standard points of posture in order to maintain balance. The handstand is maintained by subtly shifting the body's weight towards the fingers or the heel of the hand.
Popular variations of the handstand include positions with the legs extended in a side or front split, legs in a front split with knees bent ("stag split"), with back extremely arched, legs slightly bent and toes touching back of head, and one-handed. Dancers in the breakdance community employ many handstand variations as freezes or one-handed kicks.
Handstand pushups, in which one raises and lowers the body while holding a handstand, are a test of both balance and upper-body strength.
Swimmers sometimes do handstands underwater, by rolling forward, placing the hands on the bottom of the pool, and raising the legs and feet out of the water. Underwater handstands may be a game or contest between swimmers to see who can maintain the handstand the longest.
While learning the handstand, it is most common to hold the pose against a wall or other surface for support and balance. While doing a handstand, the performer always uses the base of the fingers for support, because shifting his weight back and forth across the hand is the only way to maintain balance.
When falling backwards, the performer tucks his chin to the chest and smoothly rolls down. Once this is mastered, there is very little risk involved.
The most common side effect when doing the headstand or the handstand is getting temporary bloodshot eyes.
Transitioning from a headstand to a handstand can be dangerous.
