In this conversation, Mike Piekarski discusses his experience with implementing an ecological approach to teaching Jiu-Jitsu. He explains that he was inspired by his background in physical therapy and his exposure to scientific literature on motor learning. Mike shares his observations and challenges in teaching and learning Jiu-Jitsu using this approach, including the importance of live training, the need for clear objectives, and the value of playfulness and problem-solving. He also discusses the role of time in structuring training sessions and the benefits of reducing complexity and focusing on fundamental concepts. The conversation focuses on training methods and considerations for implementing live training in Brazilian Jiu-Jitsu (BJJ). The speakers discuss the use of specific games and drills to encourage desired behaviors and improve skills. They also touch on the importance of warm-ups and injury prevention in training. Stand-up techniques and takedowns are highlighted as areas that should be incorporated into training to prepare students for real-life situations. In this conversation, Kabir and Mike discuss different approaches to warming up and gradually increasing the intensity of training. They also talk about the importance of sequencing techniques and adding and removing submissions in training. Mike shares his thoughts on designing classes and incorporating constraints to encourage playfulness and reduce the fear of getting submitted. They also discuss the concept of a 'fit test' to ensure proper grip maintenance in submissions. Overall, they emphasize the importance of experimentation and finding what works best for individual students.
