Hey Aram, finally, a really detailed explanation, which shows biomechanical relationships...simple, understandable. Alex, you're doing a great job to visualize this!!! I knew some things in detail until now, but many half-truths and so-called "trainings-guidelines"... Now I understand the importance of the "right time" for opening the upper body and the impact on the muscular "chain". This will help to work at all these little improvements that take a whole rowing-life... Perfect, thank you!!!
Hey Aram In my humble opinion to many rowers have to much pivoting motion. A lot of them lean to much forward at the catch, trying to make their stokes longer. This slows the boat at the catch. It also triggers them to open earlier than they should. If they do so, they will compensate this by leaning to much back at the finish, resulting in doing sit-ups at the finish. It may look good on the curves on the erg but it will slow the boat down also. To solve this problem I ask them to sit up straight at the catch as well at the finish. Almost no rower can achieve this and will pivot slightly in the second half of the stroke. Resulting in a compact stroke which doesn’t disturbe the run of the boat.

@ Aram The mechanics comes down to the law of cosines. If you take the average tibia to femur ratio of .8/1 and calculate the displacement vs. knee angle you see that the displacement of the seat towards the bow becomes smaller per unit change in knee angle as the legs become straight. Since velocity is just dx/dt the velocity of the rower relative to the oar lock becomes slower with corresponding impact on the angular velocity of the oar relative to the oarlock. By swinging early or even breaking the arms a bit early the velocity of the oar can be kept higher for a longer portion of the stroke, with the added benefits of engaging additional large muscle groups (as you pointed out)
I think it is as often underestimated (by masters) as it is overrated by cross fit junkies. For me, it is important to focus on strength over winter, spring and early summer, when peak of season is late summer.
It is a connection problem which sometimes occurs when rapidly changing rowing style. He simply started to early with his right hand and took away resistance from the left.

Thank you for your great comment!
Got it. Great video. Total new rower, but I understand the principles. Not too early, not too late, manage the pivot. Thank you!
To lock on efficiently so as not to slow boat and optimize leg utilization is a technical challenge and significant advantage

Being a 40+ novice rower i appreciate your explanation and advice regarding rowing technique. Thank you.
Thank you very much for your great feedback Denise!

A Locked on leg drive beats body pivot . Stronger muscles.
If blade is buried effectively then leg power maximized
How important do you believe strenght is in rowing?
I think it is as often underestimated (by masters) as it is overrated by cross fit junkies. For me, it is important to focus on strength over winter, spring and early summer, when peak of season is late summer.
Hi Aram,
How do you not disturb the boat on the recovery and into the catch to get the most distance per stroke?
Cheers Tom
Hi Aram,
I'm sorry but I can't see the plateau in the plots. Could you tell me what to look at, which curve?
Hi Anibal, it is the (short) flat part just around the peak. The goal is to have a "wide peak"... not a short one.
Aram, why is the righthand force 70% higher than the lefthand force?
It is a connection problem which sometimes occurs when rapidly changing rowing style. He simply started to early with his right hand and took away resistance from the left.
@@AramTraining And that causes a 70% increase? Just seems too much.
Hey Aram.
Just wondering, What is the price of the Bi Rower? Also, could I invest in any stock for your company?
Hey Wyatt, where are you based? Let us talk further by e mail / phone. info@aramtraining.com
when will the incentivised discount end for biorower?
I'm a fresh graduate, saving up money for the biorower.
In the US: No decision made so far. To original plan was end of Feb 19.
Hey Aram
Is small stroke and high tempo efficient??
Usually not.
Great video! Sub!
Thank you Oscar!
Just pry like a can opener. That's all.
dude i can't hear what you're saying. poor audio.
It's really not hard to hear what he's saying and i'm a guy that's partially deaf
