I'm looking to loosen up my shoulders and hips. I was told about a type of yoga that uses a 6 foot belt or strap but I don't know the name of it. I want to find poses for that type of yoga but without the name I don't know what to search for. Any ideas?

I think you are looking for Iyengar Yoga. They do lots of work with suspension and straps. I went to an Iyengar studio once that had straps and hooks coming out of the walls and ceilings to hold students in poses!

Iyengar yoga or Suspension Yoga. There are suspension setups with straps that people hang in their homes to do yoga with. They are like little mini yoga home gyms that are used to bind people into postures more comfortably and with less resistance from gravity.
