Occasionally, you will hear "experts" ask people to not do squats, because it compromises the knee, the lumbar spine and is generally considered a very risky exercise. Horror stories of debilitating injuries are often attached to such statements. Frankly, I think such statements are over-simplified and taken out-of-context, as most health-related info are nowadays, and in this case, misinformation with exercise tips are definitely not out of occlusion. The truth is squatting (with or without added weights) is essential to lower body health and is even a great tool to rehabilitate the injured body. However, it is not to say that everyone will instantly benefit from the exercise and that preventative measures need not be taken to avoid injuries. There are always exceptions to the rule. Rather, my purpose for this entry is to approach the topic of squat safety objectively and to present my interpretation of the risks and benefits of the barbell squat.
It would be convenient to picture the intra-abdomen cavity as a barrel-shaped container with nothing but air, but of course the abdomen is filled with vital organs and tissues leaving very little space for anything else. Nonetheless, and for the sake of biomechanics, let's imagine the intra-abdomen with just the skeletal frame, muscular sheaths and an air-tight skin layer.
