Janet Matthies  Head shotJANET MATTHIES

is a Boston-based an Integrative Bodyworker, specializing in strength and flexibility. Since 2002, she has worked with highly-disciplined adults, teens and children who depend upon physical dexterity for their work or their chosen lifestyle, but who may be struggling with injury, pain or lack of strength and flexibility. People call her the ‘Crazy Stretching Lady’ because of her unique, unconventional way of combining Asian yoga with western resistance training. Janet started on this path when she saw young children getting injured in school sport programs due to insufficient knowledge about stretch training. Over the years, she’s helped many athletes and other active people improve their performance, gain confidence and eliminate injury issues from their lives. Her personal mission is to educate her clients so they can become independent, rather than dependent, upon doctors, chiropractors and other physical therapists – including herself.

Janet is:

  • CPR Certified
  • Nationally Certified in the West Coast Pilates Method (
  • Nationally Certified in Resistance Flexibility and Strength training (
  • A fully Licensed Massage Therapist utilizing Swedish Relaxation Massage, Shaitsu, Zen BodyTherapy, Cupping.
  • Engaged in ongoing training in Shamanic guidance with John Myerson owner of Life Arts Center for Healing and Shamanic Study, (

Infinity Resistance Training is inspired by the Resistance Flexibility and Strength Training (RFST), Resistance Stretching, and Meridian Flexibility System (MFS) systems created by Bob Cooley. Along with Training with Bob, Janet also trained with Elite trainers Anne Tierney and Steve Sierra, with Innovative Body Solutions ( Anne and Steve were Elite trainers for Bob Cooley and have since founded the Ki-Hara Method and their own company. Meridian Training is a mind body combination of Hatha Yoga, Traditional Chinese Medicine, Resistance Training and Shamanic Healing. The effect on the body is similar to that of Acupuncture; blocked meridians become clear and unstuck resulting in increased movement of chi energy which leads to improved health and wellbeing and all kinds of other wonderful concomitant improvements.
