This is great thread.
I honestly had no idea the difference between a pressing/heaving/straight snatch balance until I attended a USAW club coaching cert this past weekend.
The way i would describe them is: presssing - pressing yourself under the bar; heaving - popping the bar upwards and dropping quickly to arms length under the bar; straight snatch balance - dropping quickly to arms length under the bar.
I was also taught that the Center of Gravity (for bar path) is the area between the ball and heel of the foot.
I'm a newbie to these lifts. And I did the cert to help coach my daughters more effectively. And I eventually want to form a WL club in the Charleston, WV area. So I would defer to others in the proper naming, etc.
Brian, you look good in what you're doing. Keep up the good work.
All the best,
