In Episode #3 of Training Chats with Israel and Mladen, we discuss the the concept of  phase potentiation in periodization. That is, does sequencing periods that place greater emphasis on certain qualities (strength, speed, etc) in a particular order lead to better performance compared with different sequences and/or without a specific emphasis on a particular quality. This is an important topic as the core of periodization models lays within this concept. We also touched the problems with simplistic reasoning attempting to explain the positive effects commonly observed with resistance training.
