Hi!
I just completed my 3:d weeks front splits program and I try to do as coach says and keep vastus medialis contracted to keep the leg straight.
It feels like there is thoughts behind everything in these programs so I am curious of why it is so important to keep leg straight. There are so many ideas about stretching out there and some recommendations is that you can get a good stretch with leg not straight and more bending by the hip.
I also can not keep my leg straight (left side) in the vertical shin wall stretch and does that mean that I miss effectiveness ?
