The Hounsfield unit (HU) scale is a linear transformation of the original linear attenuation coefficient measurement into one in which the radiodensity of distilled water at standard pressure and temperature (STP) is defined as zero Hounsfield units (HU), while the radiodensity of air at STP is defined as -1000 HU.he Hounsfield scale /ËhaÊnzËfiËld/ or CT numbers, named after Sir Godfrey Newbold Hounsfield, is a quantitative scale for describing radiodensity.
Redefine Cardio â Make traditional strength training your bread and butter and end with cardio. Close out a 40-minute workout session with 5 to 10 minutes of post-workout anaerobic conditioning. For example, consider 30-second sprints on the bike followed by a minute of rest. Repeat three times and youâre done.
This 20-minute routine combines the cardio benefits of this type of training with metabolically active-muscle building moves for a double weight-loss workout whammy!How it works: Do 1 set of each exercise back to back.After you complete the last move in the circuit, rest 2 to 3 minutes before repeating one more time (the full workout should take you 20 minutes or less). For best results, do this routine four nonconsecutive days a weekâno additional cardio needed!ow it works: Do 1 set of each exercise back to back.
