The importance of understanding physical principles
In this podcast episode, the speaker discusses the significance of comprehending physical principles when it comes to movement and force production. By acknowledging the foundational rules of physics, such as gravity and torque, individuals can make better decisions in their training and rehabilitation practices. Understanding how these principles apply to the human body allows for a deeper understanding of movement, force distribution, and fluid dynamics.
Gravity and rotational force
The podcast delves into the concept of rotational force and its correlation with gravity. The speaker explains that any rotational movement produces torque, which leads to angular momentum and procession. By grasping this relationship, individuals can better understand how fluid volumes shift, pressure changes occur, and relative motions within the body affect movement. The metaphor of celestial bodies rotating around one another helps to illustrate this complex concept.
The value of reducing relative motions
The podcast highlights the importance of reducing relative motions in certain contexts. The speaker explains that during force production, it is beneficial to decrease the rotation between body segments, allowing for more efficient force transfer. However, it is crucial to recognize that both full relative motions and reduced relative motions serve different purposes depending on the objective of the activity. Understanding the principle of rotational force and relative motions enables individuals to design more effective training programs and make better decisions in movement execution.
The need for context-specific discussions
The podcast emphasizes the significance of having context-specific discussions about movement and force production. While the episode primarily explores concepts and principles in a conceptual manner, the speaker encourages further conversations in specific contexts to apply these ideas practically. Addressing how physical principles relate to specific exercises and activities will allow for a more comprehensive understanding and application of these principles in training and rehabilitation settings.

Bill is known as a problem solver. From his small, private practice, IFAST Physical Therapy in Indianapolis, Indiana, Bill provides relief to patients in pain from all over the United States (and other countries!) who could not be helped elsewhere. His detective skills for locating the source of patients’ true problems are often compared to his favorite nocturnal comic book hero although he wears no cape or cowl (but does often wear a bat on his chest under his work clothes… you never know when a hero will be needed).
Bill is an in-demand speaker and consultant across the country and half way around the world to share his approach in regard to restoring a pain-free lifestyle to other health and fitness professionals. He regularly mentors physical therapy students and interns many of whom have gone on to land positions in professional sport or become successful business owners themselves.
Bill is also the co-owner of Indianapolis Fitness and Sports Training with Mike Robertson where he works with clients ranging from very young athletes to professionals. At the age of 50, he took his own advice and transformed himself from a painful and soft 200+ pounder to a lean and much less painful 170-pounds resulting in him being featured in Men’s Health Magazine where he is also a member of the advisory board.
Bill lives outside of Indianapolis with his wife, The Gorgeous One, along with his dog Paxton, and occasionally his adopted son Zac Cupples. To find out more about Bill and how he can help you, go to www.billhartman.net.
In this podcast, Bill and I discuss the importance of creating a working model to guide you as a professional. Beyond that Bill just drops absolutely incredibly brilliant thoughts on a variety of topics.
