Why Your Butt and Abs Workout Isn't Working (and How to Fix It)

You’ve probably seen the "Brazilian Butt Lift" programs or those "6-Pack in 30 Days" challenges plastered across every social media feed you've ever scrolled through. It’s exhausting. Honestly, most of those routines are a complete waste of time because they treat your core and your glutes like they’re two separate islands. They aren't. They’re basically neighbors that share a backyard. If your core is weak, your glutes can't fire properly. If your glutes are "asleep"—a real thing called dormant butt syndrome—your lower back takes the hit every time you try to do a crunch. We need to stop thinking about a butt and abs workout as a way to just look good in a swimsuit and start seeing it as the foundation of how your body actually moves.

Most people walk into the gym, do 50 crunches, 20 squats, and call it a day. That’s not a workout; that’s a warm-up. If you want real hypertrophy—muscle growth—and a core that doesn't fold like a lawn chair when you pick up a grocery bag, you have to understand the biomechanics of the posterior chain and the deep abdominal wall. We're talking about the gluteus maximus, medius, and minimus working in tandem with the transverse abdominis. It’s complicated, but it’s also pretty simple once you stop following the influencers and start following the science of load and tension.

The Glute-Abs Connection Most People Ignore

Ever wonder why your lower back hurts after doing leg raises? It’s because your abs checked out and your hip flexors took over. This is the biggest mistake in any butt and abs workout. Dr. Stuart McGill, a world-renowned expert in spine biomechanics, has spent decades proving that core stability is the precursor to extremity strength. Basically, if your "inner unit" isn't locked down, your brain won't let your glutes produce maximum force. It’s a safety mechanism. Your body is smart. It knows that if it fires the glutes at 100% while your spine is unstable, you’re going to end up in a physical therapy office.

When you perform a movement like a weighted bridge, your core acts as the bridge's support beams. Without it, the whole structure collapses. You aren't just trying to "feel the burn." You’re trying to create a rigid torso so the hips can do their job. This is why the best glute exercises are actually core exercises in disguise. Think about the Bulgarian Split Squat. It’s a brutal leg and glute builder, sure, but the only reason you don't fall over is that your obliques and deep core are screaming to keep you upright.

Stop Squatting for a Better Butt

I know, that sounds like heresy. Squats are the king of exercises, right? Not exactly. While the squat is a fantastic compound movement, EMG studies (electromyography, which measures muscle activation) frequently show that the hip thrust and its variations actually target the gluteus maximus more effectively. This is because squats are limited by your back strength and your ankle mobility. Plus, at the top of a squat, there is almost zero tension on the glutes. You're just standing there.

In a hip thrust, the tension is greatest at the top where the glutes are fully contracted. If you really want to see change, you need to prioritize horizontal loading over vertical loading. This isn't just my opinion; it’s a concept popularized by Bret Contreras, often called "The Glute Guy," who literally wrote the book on gluteal training. He found that the glutes are most active when the hips are in full extension. So, if your butt and abs workout is just 100 bodyweight squats, you’re leaving a lot of progress on the table. You need to get under some weight.

What Your Core Routine is Missing

It’s probably missing "anti-movements."

Most of us were taught that the job of the abs is to flex the spine—like in a sit-up. But the real, functional job of the core is to resist motion.

• Anti-extension: Keeping your back from arching (Deadbugs).
• Anti-rotation: Keeping your torso from twisting (Pallof Press).
• Anti-lateral flexion: Keeping your body from leaning to the side (Suitcase Carries).

When you integrate these into your routine, you develop that "hard" look in the midsection that crunches never provide. It creates a vacuum effect. Instead of the muscles pushing out, they pull everything in tight.

The Science of Hypertrophy in Glutes and Abs

You can't just "tone" a muscle. You either build it or you don't. To build the glutes, you need a mix of mechanical tension, metabolic stress, and muscle damage. This means you need some days where you lift heavy (5-8 reps) and some days where you do higher reps until your muscles feel like they're on fire (15-20 reps).

For the abs, the rules are slightly different. The core is comprised of a lot of slow-twitch muscle fibers because these muscles have to stay "on" all day just to keep you standing. However, they still respond to resistance. Doing 500 crunches is just cardio for your stomach. It won't make the muscle blocks pop. You need to add weight. Weighted cable crunches or hanging leg raises with a small dumbbell between your feet will do more for your aesthetic goals in three sets than 1,000 sit-ups will do in a month.

Real Talk About Body Fat

We have to mention it. You can have the strongest, most well-developed abs in the world, but if your body fat percentage is too high, they’re staying hidden. For men, abs usually start showing around 10-12%. For women, it’s usually 18-22%. This doesn't mean you should starve yourself. In fact, under-eating is a great way to lose the muscle you’re trying to build in your glutes. It’s a delicate balance. You need enough protein (roughly 0.8 to 1 gram per pound of body weight) to repair the tissue you're breaking down in your butt and abs workout, but you also need to be in a slight caloric deficit or at maintenance to see the definition.

A Better Way to Structure Your Routine

Instead of a random list of exercises, think about "The Big Three" for each area. If you hit these, you’ve covered your bases.

The Glute Trifecta:

1. A Hip Thrust Variation: (Barbell, single-leg, or banded). This is your primary builder.
2. A Hinge Movement: (Romanian Deadlifts or Kettlebell Swings). This targets the lower glutes and hamstrings.
3. An Abduction Movement: (Seated abductions or "clamshells"). This hits the glute medius—the part that gives the "shelf" look on the side.

The Ab Trifecta:

1. A Stability Hold: (Plank or RKC Plank). Focus on squeezing your glutes while you do this to "close the chain."
2. A Lower Ab Focus: (Hanging knee raises or reverse crunches). Focus on tilting the pelvis, not just moving the legs.
3. A Rotational or Anti-Rotational Move: (Russian twists with a weight or Pallof presses).

The Mind-Muscle Connection (It's Not Bro-Science)

Honestly, most people can't feel their glutes working. They feel it in their quads or their lower back. This is often due to "sensory-motor amnesia." Because we sit on our butts all day, the nerves leading to those muscles get a bit "quiet."

Before you start your actual butt and abs workout, you need to "wake them up." Spend five minutes doing low-intensity activation moves. Glute bridges with no weight. Bird-dogs. Deadbugs. Don't rush them. The goal isn't to get tired; the goal is to feel the muscle squeeze. If you can't feel your glutes when you're just lying on the floor, you definitely won't feel them when you have 135 pounds on your back.

Common Myths That are Holding You Back

1. "High reps for toning." False. High reps build endurance. If you want shape, you need muscle. Muscle comes from progressive overload.
2. "Crunches reduce belly fat." Spot reduction is a myth that refuses to die. You lose fat from where your genetics decide, usually the last place you put it on.
3. "You should train abs every day." Your abs are muscles. Like your chest or your biceps, they need recovery. Training them 2-3 times a week with intensity is plenty.

The Progressive Overload Factor

If you do the same ten exercises with the same ten-pound weights for six months, your body will look exactly the same. The human body is incredibly efficient; it doesn't want to build muscle because muscle is metabolically expensive. It only builds muscle if it’s forced to. You have to give it a reason to change.

Every single week, try to do one more rep. Or add 2.5 pounds. Or slow down the tempo. Or take a shorter rest break. This is the "secret" to a successful butt and abs workout. It’s not about the fancy new exercise you saw on TikTok. It’s about doing the boring, basic stuff with slightly more intensity than you did last time.

Practical Steps to Take Right Now

Stop looking for the "perfect" workout and start implementing these specific changes to your current routine.

• Primary Move First: Always start with your heaviest or most difficult movement. If you’re doing hip thrusts, do them first when your nervous system is fresh.
• Tempo Control: On the way down (the eccentric phase), count to three. Most people drop the weight and lose half the benefit of the rep. Control the weight; don't let it control you.
• Pelvic Tilt Awareness: During any ab move, imagine pulling your belly button toward your spine and tucking your tailbone. This prevents the lower back from arching and ensures the rectus abdominis is actually doing the work.
• Record Your Progress: Write down your weights and reps. If you aren't tracking, you aren't training; you're just exercising. There’s a difference.

Start your next session with two minutes of "deadbugs" to prime your core and two minutes of "banded walks" to prime your glutes. This simple four-minute investment will significantly increase the effectiveness of every subsequent rep in your butt and abs workout. Focus on the quality of the contraction over the quantity of the movements. Consistency over six months beats intensity over six days every single time.

Build the foundation first, add the weight second, and the results will follow as a byproduct of your movement quality.
