everything that they are doing in that video is exactly what the gym in my signature link is all about, and exactly what i keep on about here regarding function and aesthetics being intertwined with good training.
Long before gyms, dumbells, pec decks, and treadmills, there was hard physical labour - farming, sailing the seas, smithing etc. It was observed that those involved with such endeavours were much stronger and robust than the more genteel classes, for whom hard work consisted of choosing which wig to wear.
Exercise is merely a simulated increase in physical labour.
The other division people seem keen to create, is that 'old school' training can not be done or adapted to fit in with our modern understanding of physiology and kinesiology. Not so. Old school training applied with new school knowledge of the body is not only the way to go for sports performance and functional attributes, but also for those with 'buff' as their prime word of motivation.
