Body by Science

Body by Science is a book written by Dr Doug McGuff (an American emergency medicine physician who also owns a strength training fitness facility) and John Little (who also owns a gym, and is an authorised Bruce Lee biographer). Body by Science is a form of high-intensity exercise with the specific goal of increasing fitness & strength in the most efficient way possible. The book explains in detail the science of this form of exercise.

ME/CFS
There is no evidence that Body by Science is beneficial for ME/CFS patients. In fact like any form of exercise it risks causing an exacerbation of symptoms so must be approached with care.

Dr Sarah Myhill recommends ME/CFS patients consider a bodyweight form of Body by Science when they feel well enough.
