Plank is often done as part of the sun salutation sequence, or as part of a vinyasa in a yoga flow sequence. There are two variations of plank pose: kumbhakasana (full plank) and vasisthasana (side plank). You can do either as a stand-alone exercise to build core, arm, and back strength as well as improve your posture.
Megapascal is the mega unit used to measure the intensity of pressure which means force per unit area. The term pascal has been derived from the Blaise Pascal. One unit of megapascal is equal to 1,000,000 pascal units. Megapascal is generally used to measure the pressure of heavy machines such as hydraulic system.
Pascal (unit) Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa) which is equal to one millibar, and the kilopascal (1 kPa = 1000 Pa) which is equal to one centibar. The unit of measurement called standard atmosphere (atm) is defined as 101 325 Pa. Meteorological reports typically state atmospheric pressure in millibars.
