all these comments about 'feels like bludger is training for rowing'; do people realise that the power in rowing comes from the legs?
Most of what bludger is doing is going to train core strength. Upper body work would include a lot of standing rows, cable machine work, curls; I don't see any of that. He's training trunk muscles.
Not convinced that low numbers of reps are good for endurance strength training though. I do pyramids; 10 or 15 reps x 3, increase the weight between each set. Very limited time so I only do single-arm rows, crossovers, lat pull-downs and sometimes fit in curls. Really should be doing deadlifts, but gym is always super crowded.
