Hey Don,
I think what your friend is referring to is REGULAR LOW SPM ROWING. yes, that is crap. Why? it’s just slow rowing for the sake of rowing - there really isn’t an emphasis on POWER.
What I am referring to is a whole different animal.
Basically, we can debate the physiology all we want on this forum, but I recommend you try it out for yourself.
For example, if your erg goal is 6:38 you should be stroking in the 1:52-1:53 range at 24 spm for your steady state work. 1:57 is what you should be stroking for 20 spm given that erg goal.
What you are doing is trading rate for pace - you are overstroking in order to go faster. The problem is that you will eventually run out of rate - to the detriment of speed. i.e. since you never developed your power to the fullest, you will never have that fifth gear in which to really lay down the hammer in those final 250 of an erg race.
Using this new training I was able to maintain the same 2k splits (my last 2k was 6:21.4 my all time PB is 6:12.4) at 4 spm lower - i.e. I rowed the 6:21 at 32 spm and did my all time PB and all my previous tests (prior to this season) at 36-38 spm. As you can see, once the spring season rolls around and all the speed work fitness kicks in I will literally have 2 more gears that I can crank. Therefore, given the results I have gotten from this training, I fully expected to be sub 6:10 come May.
Your friend can debate that all he wants.
I would ask you this: Imagine how much faster Waddell could have been if he trained this way. He could have probably broken 5:35
About strapless rowing: you should definitely try it. It cleans up your technique big time. It forces you to use 100% of the leg drive and it turns your hamstrings into iron. You can’t cheat on the recovery by pulling on the straps to bring you up.
Low DF rowing forces you to be really quick at the catch and at the finish,(which more than raw power is the real secret to speed on the erg and in the boat ) because you can’t cheat by using the momentum the flywheel generates at the higher DF settings - it really cuts down on your leverage thus forcing you to work harder.
The beauty is that once you ratchet the DF back to 130-140 for your erg tests - ZOOOOOM!! It’s like going from a Honda to a Ferrari.
Like I said, give it try, I think you’ll like.
