Very nice analysis. Thanks for letting yourself get roasted Florian :)

Excellent ! Example of how to use the erg to row faster on the water. Efficient body mechanics and why. Well done.

très belle démonstration pour aider à éviter des traumatisme et à améliorer le rendement du coup d'aviron. rappeler les sensations sur les talons est aussi intéressant.

Aram, I have a question regarding the back positions of Florian and Alex. I have the feeling that Alex has a very rounded lower back, while Florian has a straighter lower back. I've always been taught that a rounded lower back is a bad thing to have because it overloads the lower back which leads to injury. Do you have a video about this issue and if not is one in the works or would you be able to quickly give your thoughts on this here in the comments?

I'm curious, when drawing your force vectors, why you don't speak in terms of torques around the joints. Torques could be more accurate, but perhaps not as pragmatically useful. Are the linear vectors that you draw better in your coaching experience for communicating your ideas in a way that rowers can understand, feel and incorporate into their training? I could understand that pedagogically and for coaching cues, torques could mislead - the linear vectors are perhaps easier to feel and easier to teach.

Is there an advantage to having the long-leg'd and short-torso'd structure, and is it the case that those of us with the opposite dimensions simply have some disadvantage in mechanical leverage? If one's structure includes short legs (calves and thighs, femur and tibia) and long torso, is the late hip hinge that you recommend a good way to take advantage of this structure?

Thank you Aram! You always make it so clear and interesting !🙌I can see that Alex does it the right way and perhaps the linear ergo makes it more difficult to a achieve this ? When is the right time for the back movement to aid in generating😅 speed ?

Dear Aram, I really love your videos and I learn a lot with your technical explanations. I have a question regarding the force curve obtained with an indoor rower as shown in this video. You tend to assimilate the force curve to the acceleration of the wheel Then you recommend, if I can say so, a rectangular curve rather than a triangular one (with a premature peak). You say the acceleration is constant during the plateau. However the flywheel is becoming looser while you are pulling the handle (the opposite with a rubber band easy to stretch at the beginning and increasingly resistant while you pull more). I think therefore that with a stable force the wheel will decelerate. I reckon the only way to maintain acceleration would be to increase force all along the propulsion. Torso and arms (with lats also) on the top of legs might do the job. Am I right ? I remember that Valery Kleshnev explained in Rowing Biomechanics Newsletter N°12 that triangular curves (on water) were commonly observed in champions, suggesting this type of curve was preferable to the bell-shaped curves. I imagine a delayed peak is better to prolong acceleration while with a bell curve (plateau) you may waste energy since you decelerate during the plateau. Not a simple question I confess. Thank you in advance for considering it. Jean-Luc from Paris
