Dodgers' Yoshinobu Yamamoto's Relentless Training Routine Detailed

"In December, January, he pushes himself to the point of complete exhaustion. Despite the heavy workload that Yada put on the pitcher, manager Dave Roberts is not concerned with his approach. It's from the day we signed him, how intentional he is about his work and his body care."

"In the spring the plant sprouts, in the summer the flowers bloom and in the fall the fruit appears. The same thing happens here. After a number of years, you start to understand how the [season develops]. For Yada and Yamamoto, the winter preparation is the match that lights the fire for the season."

"Yada has insisted on a program full of unconventional workouts, never making Yamamoto lift weights, instead going through an unorthodox routine. Yamamoto's trainer, Osamu Yada, known as Sensei Yada around the clubhouse, has worked with the pitcher since he was a teenager, breaking into the Japanese league."

Yoshinobu Yamamoto, the Los Angeles Dodgers' ace, won World Series MVP in his second season after leading the team in innings pitched and providing consistent performance throughout 2025. His trainer Osamu Yada has worked with Yamamoto since his teenage years in Japan, implementing an unconventional training program that avoids weight lifting. During the offseason, Yamamoto undergoes rigorous preparation, training six times weekly for six hours daily in December and January, pushing himself to complete exhaustion. Manager Dave Roberts supports this approach, noting Yamamoto's intentionality about his work and body care since signing with the team. Yada views winter training as foundational, using a seasonal metaphor where winter preparation plants seeds that grow throughout the year.
