There are some great books on foam rolling. “foam Roller Workbook” by Dr Karl Knopf is pretty good. If you mean putting together a package by showing your clients how to foam roll, first learn how to do it yourself with all the correct body positions and contraindications. I see so many people foam rolling without holding the core, backs are bowed or shoulders overextended. You could get someone to take pictures of you in each position then write good step by step directions and use it as a hand-out to give your clients. Include Piriformis, IT Band, Quads turning the toes 3 directions to get all angles of the Quads, Adductors, Calf, Thoracic Spine, Lats, Rotator Cuff. Your clients will really appreciate it in the long run.
Myo-release is something that I teach clients and students slowly. I try not to give them too many options purposely. Even experienced fitness professionals can have difficulties properly performing self-myofascial release. And I have found it is best to allow clients and students to become proficient with one technique and/or piece of equipment for a specific area at a time. After gaining some experience, progress in learning will become more efficient. But it is important to be conservative when moving on to more intense or more difficult forms of any practice.
It is better to progress a bit slower than may be possible than it is to exceed one’s abilities and cause an injury. Learning how to do this efficiently takes time and experience. I feel that as experienced fitness professionals it is our duty to assist new fitness instructors in gaining this experience for the good of the consumer and the industry.
