I just wanted to note a new fundamental technical principle I've come to understand while reading "Power Trip" by Dan McCauley:
Basically, the triple-extension that I read about, and that is often still taught to many lifters, is incorrect. According to McCauley, the extension of the ankle and knee creates unwanted forward momentum, causing both the bar and the lifter to be in inefficient positions by the 3rd pull (getting under the bar).
The emphasize should be on the hip extension and strengthening it (which would be the "3rd" extension in the triple extension). It should be the core, quite literally, of both the technique and focused strength training to maximize lifting potential.
...Learning, lifting, loving.
