Yoga Strap to help you improve and relax in poses. It is a great help in downward facing dog pose where your pelvis needs to stretch upwards while your upper body stretches forward.
Complete set to be used on door or fixed bar. Totally safe, does not damage doors. It does not require any mounting, just place it between the door and doorframe and ensure the door is well shut. You can also use it on a fixed bar.
I use it as a replacement of the traditional iyengar yoga rope in many postures such as adho mukha svanasana or uttanasana. It works wonders!
