The rotary hook or rotating hook is a bobbin driver design used in lockstitch sewing machines since the 19th century. It triumphed over competing designs because it can run at higher speeds with less vibration. Rotary hooks and oscillating shuttles are the two most common bobbin drivers in use today.
A kip-up or kick-up (also called a rising handspring, Chinese get up, kick-to-stand, nip-up, [1] flip-up, or carp skip-up) is an acrobatic move in which a person transitions from a supine, and less commonly, a prone position version known as prone get-up, to a standing position.

Alexandre-Achille Souques was one of the first major researchers of camptocormia and created the definition and name used for the condition to this day. Camptocormia comes from two Greek words, meaning "to bend" (κάμπτω, kamptō ) and "trunk" (κόρμος, kormos ), and was coined by Alexandre-Achille Souques and B. Rosanoff-Saloff. [ 3 ]
Aerial techniques, also known as "high-flying moves" are performance techniques used in professional wrestling for simulated assault on opponents. The techniques involve jumping from the ring's posts and ropes, demonstrating the speed and agility of smaller, nimble and acrobatically inclined wrestlers, with many preferring this style instead of throwing or locking the opponent.
The attacking wrestler starts by running and extending his arm like a lariat takedown but instead performs a revolution around the opponent's shoulders. This causes the wrestler to switch to his opposite arm before taking his opponent down to the mat while simultaneously landing in a seated position.
