[J-Range Training]

The two training methods that IBBAdmin was talking about does not include quarter or half reps. They are solely at the very top of the lift, like the top two inches of a bench press. That's the other problem when using DC Massey with his study is that he measured a partial range that is rarely ever used or promoted by believers in partial reps.

I do still hold the position that his research was not equally done, with the bias towards full range of motion. To me, since he noticed equal results, yet allowed 4 seconds or more less time under tension each repetition for the partial reps, that the partials actually showed more efficiency than full range. Basically, the participants doing only partial range (once again only top couple of inches) would have contracted their muscles 1 hour less after the entire 10 week program than the participants using full range. Since they both increased the same amount, that's more efficiency for the partials if you ask me.

It may also be important to note that only lifting at the very top of each movement is not the best partial range someone could use. So imagine how much more efficient the partial repetitions would be when actually comparing it along with the absolute hardest range for the muscles (which differs for everyone, and never is full range).
