I stumbled on Robert Frederic by accident, probably through Facebook. I was reading his article on Exertion Load and then I figured out that many moons ago I tried few of his apps, the last one being Strongur (which I highly suggest you try out). Robert is very interesting person: he lives in Thailand, trains Muay Thai, but he is also a developer as well as strength and conditioning coach and a lifter. Definitely someone with a broad view of things. So, after exchanging few messages with him, I decided to do a video interview and a Q&A regarding the “exertion load” metric, as well as his app. We have also touched a bit on Velocity Based Training concepts.
