To answer the question “do squats make your waist bigger reddit” directly: No, they don’t, but it’s the right question to ask. Proper squats will add 2-4 inches to your glutes over a year, while having a negligible impact on your waist size-maybe a quarter-inch of deep core muscle. This contrast is what creates the illusion of a dramatically smaller waist. You’re worried about getting a “blocky” or “square” look from lifting, and that fear is valid if you follow the wrong advice. Many people on forums and social media either blame squats for a wider waist or tell you it's impossible, but the truth is in the middle: the squat itself isn't the problem, but your form and your overall program can be.
The blocky look people fear comes from two main culprits: a layer of body fat over the midsection, or a program that overdevelops the obliques (your side abs) with the wrong exercises. Squats, when done correctly, primarily build your glutes, quads, and hamstrings. Your core-including your transverse abdominis and obliques-works hard to stabilize your spine, but this stabilization work isn't the type of stimulus that causes significant muscle growth (hypertrophy). Think of it like this: your forearm muscles work when you do a bicep curl, but your forearms don't blow up in size from curling. Your core is acting similarly during a squat. The real goal isn't to avoid squats; it's to use them as a tool to build your glutes while strategically slimming your midsection through diet and avoiding a few key mistakes.
Let's get into the mechanics. When you see someone with a thick, wide waist from lifting, it's almost never from squats. It's from two other things: high body fat or a love affair with the wrong kind of ab exercises. The fear is that the bracing motion during a heavy squat will cause your obliques to grow, widening your waist. While you do need to brace your core by taking a deep breath and tightening your midsection (the Valsalva maneuver), this primarily engages the deep abdominal wall, creating internal pressure to protect your spine. It’s an isometric contraction, not the repetitive, targeted movement needed for significant muscle growth.
The two real reasons a lifter's waist gets wider are:
So, the strategy is simple: squat to build the glutes, control your calories to reveal your waist, and stop doing exercises that directly thicken your midsection. The squat is your friend, not your enemy, in the quest for a better waist-to-hip ratio.
Building an hourglass figure isn't about magic exercises; it's about strategic construction. You build up certain areas (shoulders and glutes) while slimming down another (your waist). This creates the illusion of a smaller waist, even if its actual measurement only drops by an inch or two. Here is the exact protocol.
Not all squats are created equal. A quad-dominant squat (narrow stance, upright torso) won't give you the glute growth you want. You need to make the squat a hip-dominant movement.
The secret to a visually smaller waist is building the muscles above and below it. This is what we call building your 'upper shelf' (lats and shoulders) and 'lower shelf' (glutes and hamstrings).
This is the most critical step. You can build the perfect shape, but if it's hidden under a layer of body fat, you'll never see it. You don't need crash diets or endless cardio.
You now have the complete plan. You know which squat form to use, which accessory lifts create the illusion, and the exact nutrition strategy to reveal your work. The only variable left is execution. You know the numbers, but hitting them day after day is a different skill. That's the gap between knowing and doing.
Progress isn't linear, and the first few weeks can feel like you're going in the wrong direction. You need to trust the process.
Progress is slow. It's measured in months, not days. Take photos and measurements every 4 weeks. The scale is only one data point and often the most misleading one. The measuring tape and the mirror will tell you the real story.
Lifting heavy on squats (in the 3-6 rep range) will not make your waist bigger. The load is axial (compressive down your spine), which forces your deep core to stabilize intensely. This builds incredible core strength and density, but it does not cause the same kind of visible muscle growth as doing 15 reps of weighted side bends. Strength is a foundation for growth.
If your primary goal is a smaller-looking waist, you should eliminate direct, weighted oblique exercises. The main offenders are weighted side bends, dumbbell or plate-loaded Russian twists, and heavy cable woodchops. These are hypertrophy exercises for your side-abs, which will make your waist physically wider.
Visible abs and a defined waistline are a direct result of body fat percentage. For most women, the waist starts to look significantly smaller and more defined when body fat drops below 24%. The coveted 'ab lines' or full six-pack typically appear somewhere between 18-22% body fat. You can't spot-reduce fat from your waist; you must lower your overall body fat.
If squats cause you pain or you simply hate them, you can still build great glutes. Barbell hip thrusts are arguably better for pure glute isolation and size. Bulgarian split squats are another fantastic option that hammers the glutes and quads of one leg at a time. A combination of hip thrusts, RDLs, and lunges can completely replace squats in a program.
Waist trainers do not make your waist smaller. They do not burn fat. They simply compress your midsection, and any 'slimming' effect disappears the moment you take it off. Worse, relying on one can teach your core muscles to become lazy, as the trainer is providing the stability your own muscles should be creating. They are a waste of money and can be counterproductive to building real core strength.
