Leave 25% of your food on the plate at every meal, says weight-loss expert James O. Hill, PhD, author of The Step Diet. Save what's remaining as leftovers for a yummy lunch the next day. If you normally eat 2,000 calories or more each day, youâll cut 500 calories.
The muscles on the front of the thighs are called the quadriceps. They consist of the vastus medialis, vastus intermedius, rectus femoris and vastus lateralis. Each of these muscles get built up whenever you extend your knee. During running, this takes place when your lower legs move from a bent to straight position.
For example going for a run on the treadmill for 20 minutes requires the following: 1  Nervous system â memory of running movement patterns, action potentials to skeletal, cardiac and smooth muscle. 2  Muscular system â contraction and force production of leg muscles to run. 3  Respiratory system â inhalation of O2 and exhalation of CO2.
