Fitness influencer Chris Williamson recently joined renowned sports scientist Dr. Mike Israetel for an intense training session at Lift ATX in Austin, Texas.
The two-and-a-half-hour workout combined heavy metal music, scientific training principles, and brutally effective exercise protocols.
What emerged was a masterclass in evidence-based hypertrophy training that left Williamson struggling to walk properly for the rest of the day.
The session revealed some unconventional training wisdom that challenges popular gym narratives.

Starting With Calves: The Unconventional Warm-Up
Most lifters dismiss calf training as an afterthought. Israetel flipped that script entirely by starting the upper body session with an absolutely devastating calf protocol.
The workout began with a single giant drop set on the calf raise machine that incorporated three distinct phases: full range of motion, bottom-half partials, and an extended static hold at maximum stretch.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
I want you to come down under slow control and hold the bottom position for one full second count every single rep but at the top just pulse up and come back down.
Williamson’s reaction was immediate and visceral. The protocol left him barely able to stand for the remainder of the session.
The fucking worst thing about really hard calf training at the very beginning of a workout is for the rest of the day you’re like, you can’t stand up in a sort of sturdy masculine manner. You’re like a wacky waving inflatable arm-flailing tube man outside of a car dealership but with big calves.
The Truth About Eccentric Tempo
One of the most significant revelations from the session involved eccentric tempo—the speed at which you lower the weight.
Israetel clarified a common misconception that’s dominated fitness content for years. It’s not really about counting to three or four on every eccentric phase.
Ever since the session I did with you and Jared, you kind of pulled the rug out from underneath the tempo on eccentric as it’s not really about the tempo, it’s about control. What we do is we use the tempo as the easiest cue for control.
The distinction matters tremendously. Counting creates an arbitrary standard that may be too slow for some exercises and too fast for others.
Control means maintaining tension throughout the movement, reaching a soft pause position without bouncing, and eliminating momentum.
Myo-Reps: The Volume Equalizer
Throughout the session, Israetel implemented his signature myo-rep protocol across multiple exercises including standing cable curls, chest presses, and lateral raises.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
The concept is deceptively simple but brutally effective. Your first set establishes a target rep number—say, 15 repetitions.
Every subsequent set must match that exact number, but you can take mini-breaks within the set to accumulate the reps.
However many sets it takes, you’ll watch me do this. After I’m done with a few, I’m going to go back, I’m going to hold on to the handles probably still, I’m just going to chill for like 5 seconds and I’m going to walk forward. This is my rep match—you use myo-reps to match your first set on the second, third, fourth.
This approach eliminates sandbagging. Athletes can’t slack off and do eight reps when they could have done twelve.
The protocol guarantees volume completion while accounting for accumulating fatigue.
Why Myo-Reps Work
- Volume accountability: You can’t shortchange yourself on total work
- Fatigue management: Brief rests allow continued high-quality reps
- Time efficiency: More effective volume in less total time
- Progressive overload: Clear targets make it easy to track improvement
The Importance of First Sets
Williamson had a significant realization during the session about how traditional training approaches may be fundamentally flawed.
Many lifters treat their first working set as a “feel out” set, saving maximum effort for sets two or three.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Israetel’s myo-rep system forces a complete reversal of this mindset.
I didn’t realize until now that it makes the first set very important. I’m usually like, ‘ah yeah, you know, I’m getting into it, I’m putting my foot down, I’m starting to think about it.’ I really ramp up on set two and three. I’m not a big fan of that approach because getting into it should be part of your warm-up sets.
The logic is airtight. Your first working set occurs when you have maximum energy, focus, and strength.
That’s when you should work hardest, not later when fatigue has accumulated.
Mental Preparation and Focus
Israetel’s pre-set demeanor caught Williamson’s attention. Rather than psyching himself up aggressively before every set, the sports scientist appears almost meditative.
There’s method in this apparent calmness.
Jared and I have come to this conclusion that we’re now sufficiently able to contract our muscles hard and we’re strong enough that hyping up at the beginning of a set just increases our probability of injury but also doesn’t yield much of anything because you don’t need to be hyped for the first couple reps.
Israetel explained that he clears mental clutter before beginning. Thoughts about social perception, performance anxiety, and external distractions all create “noise” that interferes with the mind-muscle connection.

If you imagine the noise like signals on an audio input and then I go, that’s very cool. I can’t get my mojo and connect with my body really well if I have sociological clutter in my brain, so I have to let it sink.
Intensity increases progressively throughout each set, peaking during the final, most challenging repetitions where mental fortitude actually matters.
The Cybex Smith Machine Advantage
Equipment selection isn’t arbitrary for serious lifters. Israetel specifically praised the original Cybex Smith machine at Lift ATX as “the best Smith ever made.”
When pressed on what makes it superior, he identified three critical factors:
- Thin bar diameter: Improved grip comfort for high-volume training
- Extremely smooth operation: Minimal friction allows better focus on muscle contraction
- Consistent resistance curve: Unlike inferior machines that artificially increase difficulty at lockout
These seemingly minor details create substantially different training stimuli. Poor equipment introduces variables that compromise muscle targeting and increase injury risk.
Direct Forearm Training: A First for Both Athletes
Perhaps surprisingly, both Williamson and Israetel had rarely if ever trained forearms directly before this session.
When asked about the “secret” to forearm development, Israetel’s answer was characteristically blunt.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years

Same as everything else that people are good at—genetics and then effort and time. But the single largest contributor was choosing different parents, which literally you couldn’t have done.
The comment highlights an uncomfortable truth in fitness: genetic predisposition plays an enormous role in muscle development, particularly for stubborn body parts like calves and forearms.
That doesn’t mean training them is futile, but expectations should be calibrated to realistic outcomes.
High-Frequency Side Delt Training
The session concluded with lateral raises performed using a progressive rep scheme rather than the rep-matching myo-rep protocol.
Israetel revealed he trains side delts every single training session during his current mesocycle.
I train my side delts right now in this mesocycle every single time I train. This is the end of the workout, it’s very lightweight but it’s a myo-rep set. Last time I got 42 so this time it’s 45. I just add some reps every time.
This approach capitalizes on the rapid recovery capacity of lateral deltoids. Rather than absolutely destroying them once per week, frequent lower-intensity stimulation may produce superior growth for this particular muscle group.
The Evolution of Fitness Information
Toward the end of the session, both athletes reflected on how dramatically fitness information has improved in recent years.

I love what you’re doing. This era of fitness—I’m so jealous of Gen Alpha. There’s tons of shit that Gen Alpha’s got wrong, but think about how much more information is on the internet now versus just a decade ago. The fucking misc forums on bodybuilding.com, desperately trying to find out if blueberry extract and Christian Thibaudeau are going to be able to fix your side delts.
The comment captures something genuinely transformative. Evidence-based training information that was once locked behind academic paywalls or buried in contradictory broscience is now freely accessible.
Content creators like Israetel translate complex exercise science into actionable protocols that produce real results.
Key Takeaways From the Session
- Control matters more than tempo: Focus on maintaining tension, not counting seconds
- Make your first set count: Maximum effort when you’re freshest, not later
- Myo-reps ensure volume: Matching your first set prevents sandbagging
- Mental clarity enhances performance: Clear sociological clutter before lifting
- Equipment quality affects results: Smooth, consistent machines allow better muscle targeting
- Some muscles recover faster: Side delts may respond to very high frequency training
- Genetics set boundaries: Effort matters enormously within those boundaries
The collaboration between Williamson and Israetel demonstrated that scientific training principles don’t have to be boring or overly complicated. When applied with intensity and consistency, they produce remarkable results that random programming simply cannot match.
