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.
Same here i too can wear my size doctor extender any amount of hours. Drive my car, do my work, sit in office. It just take 10 to 12 seconds to wear my extender. The vaccum head is inbuilt in my extender.
