JAI Stretching Works?

Hey guys, I have been around PE for over a decade but I always lacked consistency due to life getting in the way. I started again about two weeks ago, in a good head space this time and I have been looking to go for mainly length. I remember a while back that Johann had introduced his JAI stretches.

Has anyone besides Johann been successful with gains sole from JAI stretches? If so could you relate your routine and gains?

Me, try it, do it for the next three months, ;)

I love this stretches :)

What routine did you use the JAI stretches in?
