Really happy you ask this question it's a good girth exercise:
Do you have the MOS DVD?
If not, It's free to download here on MOS.
All the exercises are in the DVD.
Here is the download link:
MOS DVD;
The link takes you to a MOS post where you can download the MOS DVD.
@Stephano2879, is the one that have uploaded the DVD through Google Drive, to make it easy for all members to get it.
It's okayed by @DLD.
If you do not have a DVD burner? You can watch the DVD internally on your computer, but you have to set up some things first on your computer (Windows). Here is a guide about that:
Run the MOS DVD without a DVD reader.
Otherwise you can burn the DVD with the program:
ImgBurn (The Official ImgBurn Website).
You are downloading a
.iso file.
You will find in the MOS DVD the
Slow Squash Jelq exercise, if you navigate to (from the main menue).
Phase 3 ->
Girth Super-sets ->
ISO.COMP.SQUEEZE (Isolated Compression Squeeze).
I'm sorry if my description to get the MOS DVD was to detailed, I just want to help out.
If you have any problems to view/run the MOS DVD, just ask me and I will help you.
I can provide picures to the guide I linked if you need that.
Keep growing brother...
