Complexes are some super potent medicine. I think Rutman used these as warm-ups to pack in some low-ish intensity skill work before he won the National Masters OL championship.
I see these as being VERY similar to the demands of a gymnastics routine. Coordinated movement flowing from one element to another. Javoric used these to add muscle to his athletes apparently. Good shite.
