Exercise Industry Firsts, Paradigms Shifts, and Myths Exposés

The following are © copyright Tom Purvis in manuals, video, and ppt. While most people using these concepts today think they either created them or are common knowledge, all were created by Tom. And unlike those that just use them as sound bites, he can support each in exhaustive detail, and has done so in monthly classes for decades.

In accordance with the former legal doctrine known as “flash of genius” he can tell you the exact moment and precipitating scenario in which each was developed, as well as the evolution from original terminology or concept to the current. (The flash of genius doctrine stated that an inventive act had to come into the mind of an inventor in a “flash of genius” and not as a result of tinkering/happenstance).

Many people have assimilated these concepts (or their partial understanding of them) as their own information without source. Tom fought over and was ridiculed for these concepts for too many decades and with too many people who were and are limited by historical continuity (ego and ignorance) for credit to not be given where it is fully warranted and due. While many professors and self-proclaimed “experts” have learned from Tom, they not only do not reference him, but they more often than not present each concept inaccurately. If you want to really know what these things mean and how they apply and to whom, there is only one person to ask.

Myth and misconceptions exposes – NASM presentations beginning 1990 (video 1994)

• Inner/outer pec
• External rotation at top of flies
• Turning feet in/out on calves
• Turning “feet” in/out on leg extensions
• Wide grip = wide lats
• Narrow grip = thick lats
• Behind the neck press: goal? Shoulder mechanics!
• Behind the neck pulldown: goal? Shoulder mechanics!
• Bench press to chest vs shoulder range, goal, and shoulder mechanics!
• Pulldown bar to chest vs shoulder range
• Upright Row
• Carrying Angle vs shoulder width grips barbell curls
• Shoulder width grips vs. narrow grip pushdowns
• Control defined eccentric range limits
• Knee over toe
• Squat misinformation “90°” is not magic, it is load, individual, goal dependent
• Knee over toe is not a knee issue, it’s a patellar-femoral issue
• Knee shear is not the problem in controlled resistance training and (has never occurred in a leg extension)
