About Us

For Yoga Teachers and Practitioners

The twin goals of Yoga Injury Prevention (YIP) are:
  1. To help people with physical or medical conditions to maintain a full and safe yoga practice
  2. To utilize the beneficial aspects of yoga to improve those conditions

YIP has been created for therapists, teachers and students, but anyone can use it. For example, it is valuable for physicians who advise their patients on the yoga they should not and should do.

  • By listing poses and giving specific conditions for which those poses are unsafe, YIP offers valuable guidance for teachers: You can state the contraindicated conditions while giving the pose to the class.
  • Yoga students can easily access the safe and unsafe poses for themselves.
  • The same goes for beneficial poses: List one or seven conditions: YIP will give you the beneficial poses that are safe for someone with all of them, and let you know which condition is benefited by each pose it lists.
Teachers and students can click on contraindicated conditions and see:
  • An explanation of why that pose is considered unsafe to practice for people with that condition.
  • For each contraindication for each pose you can see work-around poses (modifications and alternative poses) that are safe for that contraindication. To find these work-arounds, click on the contraindications. The pose variations and suggested prop use make otherwise inaccessible poses available to those with a variety of conditions.
Teachers and students can click on contraindicated conditions and see:
  • An explanation of how the that pose works to benefit practitioners, with references from the literature. There are also videos where words themselves are inadequate.
We are planning future additions to YIP
  • We are building a stand-alone smart phone and tablet app usable without an internet connection.
  • We are designing a class-planning component for teachers and yoga therapists so they can input all the contraindications of one or more people and construct and save an appropriate and safe sequence of poses for them.

The Team

Loren Fishman

Loren Fishman


After graduating from Christ Church, Oxford, Loren Fishman, MD, B.Phil. (oxon) went to India for three years. There, he studied daily with BKS Iyengar for almost a year, until Mr. Iyengar said, “Now you can teach my yoga.” Dr. Fishman returned to the USA, went to Rush Medical School in Chicago, joined the New England Medical Center-Harvard Residency program and became Chief Resident at the Albert Einstein College of Medicine. His specialty is physical medicine and rehabilitation.

Since his student days, Dr. Fishman has integrated yoga into his medical practice, working with both patients and health professionals. He himself has been practicing yoga daily since the year he spent with Mr. Iyengar, has written and edited more than 97 academic articles and chapters, and 11 books. Six of these books are about yoga and medical conditions.

Among his writings is a peer-reviewed article about yoga injuries based on e-interview of 33,000 yoga teachers and therapists. Dr. Fishman has also published peer-reviewed research on osteoporosis, piriformis syndrome, scoliosis, and prize-winning research on yoga for shoulder pain, which he is now studying under an NIH grant.

  He has published articles in the journals Spine, Muscle and Nerve, Archives of Physical Medicine and Rehabilitation, Topics in Geriatric Rehabilitation and a number of international periodicals. He is past president of the New York Society of Physical Medicine and Rehabilitation, currently Associate Editor of Topics in Geriatric Rehabilitation, on the staff at Columbia College of Physicians and Surgeons, and Treasurer of the National Zoster Foundation.

Dr. Fishman has been a keynote speaker at the International Association of Yoga Therapists’ meetings, and at the Smithsonian Institute in Washington, D.C. He has been extensively interviewed in the media, including The New York Times, the Wall Street Journal, CNN, and CBS World News Tonight.

The two principal founders of YIP have their roots in the work of Mr. BKS Iyengar.* The impetus for the site was to let others have the advantage of his direct teaching, and close to 100 years of combined teaching, further learning, and clinical application of his anatomically sophisticated and therapeutically oriented, surpassingly strong and beautiful yoga.

Victor Oppenheimer traveled to India every other year for more than twenty years to attend intensive three week long workshops with Mr. Iyengar. He has been certified directly by Mr. Iyengar to teach his style of yoga.

Victor was instrumental in the formation of the Iyengar Yoga National Association of the United States. He founded the yoga.com website. He co-chaired the Boston 1987 B.K.S Iyengar Yoga Convention. He has certified Iyengar teachers, conducted many teacher training workshops, and taught extensively both in the USA and abroad.

Victor has been a devoted practitioner and teacher of the Iyengar style of yoga for more than forty years.

Along with Taliesin Oppenheimer, Carrie Owerko, Carol Ardman, Jennifer Elsner and James Anderson, they have created YIP in order to open up to everyone their combined experience in avoiding yoga injuries and healing a fair number of conditions. For some, such as low back pain, osteoporosis, scoliosis, restless leg syndrome, insomnia and certain shoulder injuries, yoga has been shown as good or better than the currently mainstream medical options.

Who was Mr. Iyengar?

BKS Iyengar (1918 – 2014) was a world acclaimed master yoga practitioner, inspirational teacher, and prolific author who devoted his life to exploring and teaching yoga. He is widely acknowledged as being responsible for bringing the awareness and practice of physical yoga from India to the West. Countless people throughout the world have had their lives changed for the better from his teaching.

Mr. Iyengar was particularly interested in yoga therapy and he devoted many years to helping people with a variety of physical ailments and problems through yoga. The techniques he evolved have proven highly effective and are now in widespread use throughout the globe.

The founders of Yip feel privileged to have received extensive personal training from BKS Iyengar. We have created YIP to integrate knowledge from this training with advances in contemporary medical science. We hope the power of modern information technology will enable an even larger audience to safely experience the benefits of the practice of yoga.
