Just read this this morning. I wasn't a huge fan or follower of his material over the past many years, but he was a staple for me during the 90's and early 2000's. He had a huge influence for many years, and he helped lift the training discussion greatly years back in the 90's with his columns and Q&A in MM2K and later with Tnet. May he RIP.
Very sad day. Poliquin didn't invent concepts like German Volume Training or antagonistic supersets, but he popularized them and brought them to whole new audiences. I started reading his work back in the old Muscle Media 2000 in the 90's, and have followed him ever since.
I don't agree with him on everything, but I appreciated his work and he had much to offer to others. A tragedy for the strength and conditioning community.
