The facility for callisthenic exercise (using own body weight).
Press-ups on low and high bars can be performed even by beginners, however, they are not easy. When performed in a right manner, they involve an enormous number of upper body muscles. This is definitely much more demanding exercise than regular press-ups. They particularly engage chest muscles, triceps, arms and many other muscles which are responsible for proper body posture, like the trapezius and stomach.
