Check my previous post. Do you think Ed Coan could row strictly with 500lbs?
...yes I'd say Ed Coan could Pendlay row with 500 lbs as it seems the Pendlay row is simply a flat-backed version of what I do. Except that your video showed you pulling the bar
straight to your upper stomach. When I say pull to the lower stomach I mean just that. I touch the bar to my upper thighs and that means pulling in an arc, which is much more difficult and requires keeping the elbows at your side.
So using your 250 lb rows as an example, Van Bilderass:
-start using an Ez-bar as this will help you clear your knees during the lift
-start using an arched back throughout the movement (that'll cost you about 75 lbs off the bar)
-start pulling to your lower stomach/upper thighs (that'll cost you another 50 lbs off the bar)
-don't let the bar rest on the ground (with an arched back your hang position will put the twenty plates about 6 inches or less off the ground)
..however, that strict movement with 125ish lbs will build significant muscle. More importantly, you will be able to "feel" your lats the same way that you feel your pecs while doing a bench press.
Just to show off my encyclopedic knowledge of all things iron... I'd hazard a guess that my projected 125 lb working row weight for Van_Bilderass is (as it should be) 40% of his current working deadlift weight, and approx 60% of your current working bench weight (assuming no imbalances).
Am I right??
