I was first introduced to complexes by my crew crew coach last winter. He wasn't a big fan of focusing on powerlifting focused strength routines, because he feels they don't have much carryover to the boat.
However, I felt that his weight circuits weren't heavy enough to elicit much growth or increase in strength. We would generally do 9-10 sets of 6 exercises with 10 reps, but just use the bar. It wouldnt be until the last set or two that you'd feel anything, because of the low weight. I just kind of assumed they weren't too useful. However, now I've been doing some reading up on complexes (mostly the T-Nation articles by Alywn Cosgrove). They actually look pretty effective for getting a good dose of cardio and building strength.
Does anyone have experience implementing these into the training??
