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.
1 Circuit training will not increase muscle mass and may even break down muscle proteins if you do train for more than an hour. 2  If you do the cardio after circuit training, you will be burning muscle instead of fat. 3  That's why the week schedule was designed, to allow your body to adapt to burning fat instead of muscle. So, lets say you used to do 2 hours per week cardio (4x30 mins), by doing circuit training not only do you save that 2 hours but also another 72 mins per week (4 x 18 mins). 2  That's well over an extra 3 hours per week to paint, write, watch TV, re-acquaint yourself with your significant other, whatever you want.
