The muscles of respiration are the muscles that contribute to inhalation and exhalation, by aiding in the expansion and contraction of the thoracic cavity. The diaphragm and, to a lesser extent, the intercostal muscles drive respiration during quiet breathing. The elasticity of these muscles is crucial to the health of the respiratory system ...
Abdominal muscles have many important functions, including breathing, coughing, and sneezing, and maintaining posture and speech in a number of species. [4] Other abdominal functions are that it helps "in the function of support, containment of viscera, and help in the process of expiration, defecation, urination, vomiting, and also at the time of childbirth."
The lungs are not capable of inflating themselves, and will expand only when there is an increase in the volume of the thoracic cavity. [6] [7] In humans, as in the other mammals, this is achieved primarily through the contraction of the diaphragm, but also by the contraction of the intercostal muscles which pull the rib cage upwards and outwards as shown in the diagrams on the right.

Kipping pull-ups are considered high risk for injury and are a major cause of shoulder injury in CrossFit athletes. [15] Muscle-up: A pull-up that transitions to a dip; it is more difficult than a pull-up and requires significant strength and technique to execute. Originating in gymnastics, it is also popular in CrossFit where it may be ...
The muscle fibres of the diaphragm radiate outward from the central tendon. While the diaphragm is one muscle, it is composed of two distinct muscle regions: the costal, which serves as the driver in the work of breathing, and crural diaphragm, which serves as an "anchor;" attaching the muscle to the lower ribs and lumbar vertebrae.
Achieving the level of excellent pull-up performance means your back, biceps, forearms, and core are all firing on all cylinders. So, if you can hit 15+ pull-ups, you’ve earned the "excellent ...
Exercises focusing on the legs and abdomen such as squats, lunges, and step ups are recommended to increase leg and core strength, in doing so, reduce the risk of falling. [9] Bodyweight exercises provide multi-directional movement that mimics daily activities, and as such can be preferable to using weight machines.
Olson shares that “negative pull-ups” are also a great starting point. “Use a chair or bench. Hang from a pull-up bar in the flexed (ending/up) position,” she explains of the exercise.
