Dr. Mike Israetel recently took a critical look back at his own training history, spotlighting three technical mistakes that hampered his muscle growth and increased injury risk.
In a candid video for RP Strength, the seasoned coach dissected old footage of himself lifting, revealing exactly what he’d change if he could start over.
These aren’t minor tweaks—they’re fundamental shifts that could mean the difference between steady progress and chronic setbacks.
For anyone serious about building muscle safely and efficiently, his insights offer a masterclass in evidence-based technique refinement.

The Momentum Problem: Bouncing Your Way to Injury
Israetel’s first major mistake involved excessive momentum, particularly rapid reversals at the bottom of movements. Looking back at footage of himself squatting 405 pounds for 14 reps at 240 pounds bodyweight, he noticed something troubling.
I’m bouncing a crapload out of the bottom.
This pattern extended to other exercises too. In another clip, he performed skull crushers with 195 pounds, demonstrating impressive strength but problematic form.
I’m bringing the skull crusher back to my nose at the bottom and then swinging through to press the weight at the top.
Active Tension vs. Passive Tension
The core issue with momentum-driven lifting lies in understanding how muscles actually grow. Israetel explains that muscle growth primarily comes from active tension—force generated by muscle contractions.
When you bounce out of the bottom position or use excessive momentum, you’re creating passive tension instead. While passive tension does stimulate some muscle growth, it’s significantly less effective than active tension.
The real kicker? The injury risk skyrockets with momentum-based lifting, while slower, more controlled movements produce equivalent muscle growth with dramatically better safety profiles.
Two Solutions for Safer Lifting
Israetel offers two practical approaches to fix this problem:
- Gentle reversals: Slow down at the bottom and reverse direction smoothly without pausing completely
- Full pauses: Come to a complete stop for one to two seconds at the bottom of each rep before pushing back up
Both methods drastically reduce peak forces at vulnerable positions while maintaining muscle-building effectiveness.
Study after study after study shows slowing things down, pausing things causes basically the same amount of growth as a very dynamic explosive momentum based reversal lifting.
Which approach should you choose? Israetel suggests considering your age, injury history, and current training phase. Older lifters, those with previous injuries, or anyone in contest prep should lean toward full pauses. Younger, injury-free lifters can safely use gentle reversals.
Using the Wrong Muscles: When Your Ego Hijacks Your Form
Israetel’s second mistake involved allowing secondary muscles to dominate movements intended for specific targets. His prime example? Low-bar squats.
In footage of himself squatting 560 pounds for doubles, Israetel identified a critical flaw in his approach.
I’m using my glutes a ton more and I’m concomitantly using my quads less.
The low-bar position forced him into a forward lean with reduced range of motion. While this technique maximized the weight he could lift, it completely undermined his actual training goal: building bigger quads.
Losing Track of the Target
Israetel uses a simple analogy to illustrate this problem. If your goal is to go to the store, it doesn’t matter whether you walk, bike, or drive—but if you drive to the gas station instead and come home, you’ve failed your objective.
Similarly, when your goal is quad development but you modify your squat to lift maximum weight, you might build impressive glutes and back strength while leaving your quads understimulated.
This mistake typically stems from the universal desire to progress in weight lifted. Unfortunately, that pursuit can completely override the fundamental purpose of hypertrophy training: stimulating specific target muscles.
The Fix: Technique Selection and Mind-Muscle Connection
Correcting this error requires two deliberate steps:
- Choose techniques that actually hit your target muscle (feet closer together and lower on the hack squat platform for quads, wider grip with flared elbows on bench press for chest)
- Maintain mind-muscle connection throughout each set to prevent compensatory patterns from creeping in
Yes, this approach means lifting less weight. But Israetel emphasizes that targeted stimulus with lower fatigue beats indiscriminate heavy lifting every time for physique development.
Modifying Technique for Progression: The Silent Gains Killer
Israetel’s third mistake involves subtle technical modifications made specifically to squeeze out extra reps or weight progressions—at the expense of actual muscle stimulation.
This error manifests in two primary ways: uncontrolled eccentrics and shortened range of motion.
The Eccentric Abandonment
Many lifters—including past versions of Israetel himself—essentially freefall through the lowering phase of exercises. This is especially common on pull-ups and curls.
The motivation is simple: uncontrolled eccentrics conserve energy for more concentric reps. If you drop quickly through pull-up descents, you might hit 10 reps with 50 pounds hanging from your belt instead of just six or seven with controlled negatives.
But those extra reps come at a steep cost. Controlled eccentrics generate substantial muscle growth stimulus, and abandoning them means you’re working harder for less results.
The Range of Motion Compromise
The second component of this mistake involves cutting range of motion short, particularly at the stretched end of movements.
That deep stretch at the bottom of pull-ups or the full extension at the bottom of a Romanian deadlift creates enormous growth stimulus. It also demands significant muscular energy.
By avoiding these deep stretch positions, lifters can perform more reps with heavier loads. Unfortunately, they generate equal or greater fatigue while producing less actual muscle growth.
It’s like if you’re training special forces soldiers and you never put them into really bad environments where they have to think on their feet and really struggle to make sense of the situation and then solve problems, they’re going to have an easier time and be able to get through special forces training like half the time that it normally takes.
But easier training produces inferior soldiers. Similarly, easier lifting produces inferior muscle growth.
The Solution: Establish Non-Negotiable Technical Standards
Fixing this problem requires establishing controlled eccentrics and full range of motion as absolute requirements—technical standards that never get sacrificed for progression.
This approach will slow your weight progression. You might add 2.5 pounds per week instead of 5 pounds. But the stimulus your muscles receive will be dramatically superior.
Israetel emphasizes that months or years later, when you’re lifting the same weights you used to lift with poor technique, you’ll be significantly bigger despite using identical loads. Same stress on joints, same injury probability, but way more muscle.
Balancing Ego and Intelligence
Throughout the video, Israetel acknowledges the important role ego plays in training motivation. Attachment to weight and rep numbers drives consistency, organizes lifestyle choices around training, and provides objective progress metrics.
The solution isn’t to abandon progression tracking—it’s to add another layer of concern.
You want progression. You want ego. You want a lot of weight on the bar and more every week and every other week, but you also want to make sure the technique is targeting the muscles you want and keeping you as safe as possible.
Israetel compares this to regulated MMA competition. Fighters absolutely attach their ego to defeating opponents, but they operate within rules that prevent eye gouging, groin strikes, and poisoning competitors. These constraints don’t make the sport less legitimate—they make it sustainable and safe.
Similarly, attaching your ego to progressive overload within the constraints of excellent technique produces optimal results. You get maximum muscle growth at minimum injury risk.
The Long Game Wins
Israetel’s fundamental message centers on training longevity. The lifter who can string together the most quality workouts over months and years—without significant injury interruptions—will ultimately achieve the best physique.
Momentum-based lifting, wrong muscle recruitment, and technique modifications for progression all share a common flaw: they sacrifice long-term consistency for short-term performance metrics.
The three corrections work together synergistically:
- Controlled tempos and pauses dramatically reduce injury risk
- Proper muscle targeting maximizes stimulus per unit of fatigue
- Full range of motion with eccentric control optimizes growth from each rep
None of these adjustments require fancy equipment or complicated programming. They simply demand honest self-assessment and the discipline to prioritize what actually works over what feels impressive in the moment.
For lifters willing to check their ego at the door—or more precisely, to redirect that ego toward meticulous technique rather than pure numbers—these principles offer a roadmap to safer, more efficient muscle building that compounds over years of consistent training.
