Great video Prof., I have noticed over the years, using both these variations, when it comes to pushing light to moderate weight, the seated leg curl machine works just fine, but when it comes to going heavy, most of the seated leg curl machines tend to push our lumbar spine away from the back rest, leading to lesser effectiveness overall. On the contrary whenever I have used the lying leg curl machine, the tension I’ve felt in my hams was much much greater, even allowing me to push a little more weight, I do understand the biomechanical difference at the hip, but that has been my experience.

Good point, I've noticed the same thing with heavier loads. Definitely affects the biomechanics...
