Belt Squat Isometrics

Here is a common question we hear all the time about using the Triphasic Training methods: "What if you don't have spotters?" Cal's answer was really good, and it kind of flips the whole conversation on its head. The old thinking was: no spotters = no super maximal eccentrics = you're missing out. But Cal's take? The belt squat isometric might actually be the better option — not the backup plan. Here's Why The Belt Squat First, the safety piece. No spinal loading. No fear of getting buried...

The Magic Isn't in the Plan - It's in the Execution We are back and soooo apologize for the long radio silence. It has been super busy for both of us, but we are committed to sending you a ton of great info coming up. First off, a huge congrats to Coach Cal and the Women’s Olympic Hockey team for taking Gold just the other day! Cal is still in Italy with the team. Huge congrats!! One of the most common questions we get is: "If I only have 6-8 weeks, how do I set up a simple Triphasic...

Have you ever watched an athlete who looks explosive in warm-ups... but can't seem to fire their glutes when it matters? We see it all the time. The athlete who can squat 400+ pounds but their glutes shut off the moment they sprint or jump. In Triphasic Training II, we call this the "firing pattern disaster"—and it's probably costing your athletes more performance than you think. Here's the thing: Most glute activation drills are garbage. Clamshells? Please. Glute bridges for 20 reps? Come...

First off, my sincere apology for the ill communication here; between myself traveling to Europe at the last minute to some professional athletes to Cal traveling all around and then I was at the ISSN conference, a few shipping / website hiccups, project deadlines etc, ,time just got away... ...but we are back now and today I have a podcast with the man himself- Coach Cal Dietz. This was originally a bonus call for the Phasic 2 book, but it was packed with so much gold, I had to bring it to...

Dr Mike T here and I am stoked to let you know that the wizard himself Coach Cal Dietz has a breakthrough new program that's going to change how you think about ACL injuries. As you know, non-contact ACL injuries are absolutely skyrocketing... ...but here's the thing: you don't have to accept this as "just part of the game." Cal has cracked the code on something that's been hiding in plain sight for years, and he's put together a brand new program that shows you exactly how to slash ACL...

Two things for you today from raining Minnesota 1) New printer for the Triphasic Training II book We have a new printer for the Triphasic Training II book now. Same book, same layout, and no difference at all, but this will serve as a back up and we can control all aspects of the process now instead of bowing down to Amazon if anything were to happen. You should not notice anything different, but if you live outside of North America, it may be cheaper on Amazon as the new printer ships from...

I know I am going to sound like a broken record here, but this system seems to still get no love. As you know I am talking about…. ….The aerobic system. In Triphasic Training II, we dedicated almost 25% of the book to aerobic capacity—and for good reason. This isn’t just about long runs or “getting in shape.” It’s about building the engine that drives recovery, repeatability, and even max-effort lifting. “A bigger aerobic system equates to a better-functioning athlete who can absorb more...

Have you ever trained an athlete who crushes the gym... but falls flat on the field? I am sure you have; all of us have been there. We are willing to bet you a custard donut that it’s a transfer issue—and it’s one of the most frustrating things for coaches to deal with. In Triphasic Training II, we dive deep into this problem and introduce a complete Transfer Phase, built around one key idea: “At what point are your athletes strong enough? If Volleyball Vicki back squats 275, and you grind...

Question- how do you start your sessions with your athletes? I know you are following us here so odds are you are already doing this, but many “out there” are still not convinced. In Triphasic Training II, we introduced the Turn On Phase—a crucial upgrade to what most people call “warm-up.” This phase isn’t just about body temperature. It’s about activating the correct muscles, reinforcing movement patterns, and optimizing output. “Some coaches believe warm-up activities are a waste of...

Greetings from Weatherford TX where today's question is: Are you ready to elevate your training programs beyond individual exercises and start programming from a systems-level view? In Triphasic Training I, we focused on the "micro"—eccentric, isometric, concentric components of exercise. That was all about optimizing the rep. But now it’s time to go macro. Triphasic Training II introduces the Turn On, Train, Transfer (TOTT) system: a blueprint for aligning the full training session with...
