If you google X4 labs the quad support head attachment is on their site.
I perform manual stretches but with a lengthmaster and resistant band set up. I do this so I don’t have to use my hands at all and the stretch is stronger. My entire PE career was a decon break up until the end of last summer when I got serious about it. Since then no breaks.
Yes it is capable of the same hours. I wore mine from 9am to 10:30pm today. Removed it for no more the 5 minutes at a time if I had to use the bathroom. I don’t usually get in this many hours but the farthest I went today was the balcony lol. Just a day of hanging in for me and getting some work done.
