Triphasic Training for Sport

You know the name. You’ve seen his work. Longtime coach, academic, and author, Cal Dietz [@Cal.Dietz] joins us this week to talk Triphasic with The Crew. Familiarize yourself with the content by heading to the Calvin Dietz YouTube channel and going full nerd. It won’t surprise you that the efficacy of Triphasic and any power program is hugely dependent on proper nutrition and recovery. How tight is too tight for great power potential and where is the happy median for optimal muscle contractions?

Cal brings a ton of knowledge and case study to the table as he discusses the optimal ranges of motion for sport. What about the quarter squat and knees over toes position primes athletes for power? Additionally, his experience tinkering with loads and percentages may challenge what you thought you knew about working within a certain range for speed work. If you had over $100,000 worth of testing equipment to delve into the individual adaptation of each of your athletes, you might be half as smart as this week’s guest.


Cal Dietz has a ton of content floating around out there. A good place to start is his website: www.XLAthlete.com. There you can find links to his publications including several books based on building Triphasic Training and cycling it appropriately into your program. Cal also has a YouTube Channel that helps illuminate the concepts and mechanics of Triphasic training exercises. You can search the name Calvin Dietz or find the link in our show notes.

    If I’m not mistaken, the “weight on the heels” in the squat comes from multiply powerlifting, where doing so and keeping your shins closer to vertical would get the strongest flex out of the squat suit: i.e. squat more. (not sure anyone really cares, but you can blame Louie Simmons if you reaaaaaaaally want a scapegoat)
