Poliquin is a resident of Ottawa, Ontario, and has trained numerous Olympic athletes. He was born on March 5th 1961 in Ottawa, Canada. Until the age of 12 he lived in his birth country, then he moved to the United States with his parents. As a talented soccer player he was in the Irish under-17 squad eight times. A knee injury prevented him from becoming a professional, so he dedicated his life to weight training. He gave his strength-training advice in monthly articles to the general public through the online and print versions of Testosterone Magazine (now known as T-Nation).[original research?] Poliquin has published several books, many of which have been translated into 12 different languages, including English, Swedish, German, French, Italian, Dutch and Japanese. As a columnist, he has written over 600 articles in numerous publications. His first book The Poliquin Principles formatted a basic summary of his training methods and provided insight into the training regimens of some of the world's top athletes. Poliquin, who is fluent in English, French and German, also promoted and helped popularize German volume training.
Poliquin founded and opened the Poliquin Strength Institute in East Greenwich, Rhode Island, where he trains and certifies coaches in the Poliquin International Certification Program (PICP). As part of his certification program he teaches a body hormone profiling method, which he invented, called BioSignature Modulation.
