Yes, that is what I thought for a long time until I came across a piece of research by a Japanese team that suggested that the exercise develops the psoas muscle and hip flexors. 1 piece of research isn’t enough but if you consider that S Francis believes in doing a lot of them there maybe something in it…

I may suspect that it is better as a exercise to train hip extension.

No matter, Im sure we can agree that it is a great exercise, and I like to include it in my routine.
