That idea sounds interesting. I've heard a similar idea of doing reps in the 3-5 range with multiple sets and little rest.
I remember your journal mentioning this, so how have the results been? What type of exercises would you use this on? If your form wasn't really suffering, wouldn't this method only really have speed of movement going for it?
It'd be like: 4 reps 15 s 4 reps 15s 4 reps 15s 4 reps 15s instead of
8 reps 1-2 minutes 8 reps
I guess that'd also work endurance then like you said? But what about TUT?
