The sacroiliac joints (SIJs) are specialised structures that serve as stable yet slightly flexible connections between the lower limbs and the rest of the body, allowing efficient force transmission. These joints are large, flat, and combine both synovial and fibrous elements. Their highly congruent surfaces offer considerable friction, and strong ligaments further support their function, resulting in effective force transfer with minimal movement (Vleeming et al. , 2012).

Life is healthy feet. Anyone who has suffered from a foot injury can attest to how quality of life is ruined by unhealthy feet. The foot is the only part of the body to regularly contact the ground. Comprised of 26 bones, 33 joints, 19 muscles, 107 ligaments, 10 tendons, the foot is arguably the most mechanically complex part of the body - so much so that Leonardo da Vinci called the foot a work of art. Generally, the properly functioning foot needs 30° of inversion, 20° of e

When it comes to low-back strength and posterior chain development in athletic performance, no exercise has the characteristics of the seated good morning. This exercise has been used for several years by Soviet Union weightlifters in the 70's and 80's and it was an integral part of their training regime. Legendary weightlifting coach Alexei Medvedyev, in his book A System of Multi-Year Training in Weightlifting , wrote that "seated good mornings on a bench and on the floor

For an optimal understanding of how inertial machines work, the first important step to take is to have a clear knowledge of the basic physics principles behind the concept of inertial training. This is fundamental since not having a basic knowledge in physics will lead us to erroneous conclusions as well as doing wrong comparisons between different types of equipments. Inertial (or flywheel ) machines work under the principle of the accelerated Uniform Circular Motion, which
