What muscles does running work? Running works the quadriceps, hamstrings, gluteals, hip flexors, abs, calves, tibialis anterior and poroneal muscles. Although the exercise does not build these muscles or make them stronger, it does make them capable of greater endurance.
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.
