Popular fitness YouTuber Jeff Cavaliere recently shared a game-changing approach to ab training that most people get completely wrong.
In his latest video, the physical therapist and strength coach revealed why countless gym-goers waste time on ineffective crunches and planks.
His solution? Stop counting reps and start making every single repetition count through intentional muscle contractions.
The difference between mediocre abs and visible definition might come down to one simple shift in mindset.

The Fatal Flaw in Most Ab Workouts
Cavaliere demonstrated the problem using his colleague Jesse, who performed what appeared to be textbook crunches. Jesse wasn’t yanking on his neck or shortchanging his range of motion—two common mistakes that plague ab training.
Instead, he was committing an even more insidious error: mindlessly going through the motions without focusing on actual muscle contraction.
If you’re doing what he’s doing right here, I promise you, it’s one of the reasons why you’re probably not seeing the results that you’re getting from ab workouts right now and maybe even one of the reasons why you stopped doing ab workouts altogether, cuz you feel like they’re kind of a waste of time.
According to Cavaliere, this distinction separates those who build impressive core strength from those who spin their wheels indefinitely.
The “Painting” Technique for Perfect Crunches
For basic crunches, Cavaliere introduced what he calls the “painting” visualization. Rather than lifting shoulder blades as one rigid unit, he instructed Jesse to imagine painting his spine one vertebra at a time off the ground.
This deliberate, segmented approach forces genuine abdominal engagement. Jesse struggled to even speak during the demonstration—clear evidence that intentional contraction creates exponentially more muscle activation.
You paint up, you paint down. What I mean is one vertebrae at a time comes off of the ground, and one vertebrae at a time gets painted back down on the ground.
When performed correctly, this eliminates the need for endless repetitions. Quality trumps quantity every single time.
Dialing In Oblique Contractions
Side crunches present even greater challenges for maintaining proper muscle engagement. Cavaliere emphasized identifying the target area—the obliques—before initiating any movement.
He used an unusual but effective analogy involving a tripod attachment plate. The feeling of screwing in that loose attachment mirrors exactly how oblique contractions should feel when properly executed.
This kind of looseness that you have, this is the act of actually trying to find the right way to initiate the contraction. I’m going to find that obliques. Here it is. Okay, good. Now, once I have it, then I lean in.
The process follows three distinct phases:
- Identify the oblique muscle group
- Contract intentionally before moving
- Intensify that contraction while lifting—the “screwing in” sensation
Speed becomes irrelevant. Precision matters infinitely more.
Lower Ab Training Without Back Strain
Lower abs represent perhaps the trickiest area to train effectively. Most people inadvertently transform lower ab exercises into lower back strength tests.
Cavaliere recommended placing hands beneath the lower back for additional support, particularly for those with existing back weakness. This simple adjustment protects against excessive arching.
For proper execution, he instructed thinking about dropping the stomach down, pulling inward to flatten abs, then curling the pelvis upward. This reverses typical movement patterns that rely primarily on hip flexors.
I’m painting the pelvis and the sacrum off, lift, paint it back down one piece at a time.
Leg position simply adjusts resistance—straight legs create maximum difficulty, bent legs reduce loading. Regardless of leg angle, intention remains constant: initiating movement from abdominal contraction, not momentum.
Transforming Boring Planks Into Brutal Core Builders
Cavaliere makes no secret of his opinion on standard planks—they lack sufficient challenge for meaningful adaptation. However, he endorses the RKC (Russian Kettlebell Challenge) plank variation for creating total-body tension.
Traditional planks allow passive hanging. RKC planks demand aggressive engagement:
- Pull toes toward elbows (they won’t move, but create tension)
- Pull elbows back toward toes in rowing motion
- Create posterior pelvic tilt by curling tailbone under
- Pull abdominals up and inward
Jesse couldn’t maintain this position for even 45 seconds—proof positive that genuine engagement transforms exercise difficulty.
That is an engaged plank. That is one that you’re not going to be able to hold for 3 minutes, 5 minutes, 10 minutes, or whatever.
The Philosophy Behind Effective Ab Training
Cavaliere’s core message transcends specific exercise modifications. He advocates fundamentally rethinking how we approach muscle contraction during training.
Feeling muscles work matters more than completing prescribed repetitions. When struggling to develop visible abs, insufficient contraction focus typically explains disappointing results.
I say stop counting reps and make your reps count. If you want more out of your ab training, then forget about the repetitions and make everyone count.
This philosophy applies across all resistance training, not exclusively abdominal work. Mindful contraction builds muscle. Mindless repetition builds frustration.
Beyond Exercise: Nutrition for Visible Abs
Cavaliere acknowledged that exercise represents only half the equation. Visible abs require appropriate body composition achieved through proper nutrition.
Even perfectly developed abdominal muscles remain hidden beneath excess body fat. Training builds muscle; nutrition reveals it.
His recommendation? Combine intentional contraction training with structured nutritional approaches designed to reduce body fat percentage while preserving lean tissue.
Together, these strategies create the complete package: strong, defined abdominals that actually show.
