what parts of the body does running work
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.
Your arms are important for balance as you run. Moving the arms in rhythm with your legs can also control your speed. Keeping your arms bent at a 90-degree angle keeps your biceps contracted, working them throughout your run. The forward and backward motion of the arms helps work your triceps and shoulder muscles.
