As discussed, the continuum does involve aerobic muscle fibers even in primarily anaerobic activities. They simply don't contribute much to the overall effort. Again see the chart here. The aerobic component is well less than 5% for activities well past the low rep high weight range. Even if it were 20% aerobic component, that would still qualify as primarily anaerobic. Do you have some reliable sources for this idea of yours that low rep high weight trainging provides an important aerobic training component? EPOC doesn't count, that is simply the body recovering from the anaerobic work. It uses oxygen, but is not aerobic in the same sense. -  16:50, Mar 23,
