Why You’re Not Building Muscle (and How to Fix It)

Writer: Alex NielenAlex Nielen

So, you’ve been lifting weights and flexing in the mirror like you’re auditioning for the next Baywatch movie. But somehow, your muscles still look the same. You’re starting to wonder if your gym membership is just a really expensive way to hang out with strangers in leggings. Sound familiar? Don’t sweat it—building muscle isn’t as straightforward as it seems. Let’s break down why you might not be seeing gains and how to fix it.

How Do We Build Muscle in the First Place?

Before we dive into why you’re not building muscle, let’s talk about how muscle growth actually works. When you lift weights or do resistance training, you create tiny tears in your muscle fibers (don’t worry, this is a good thing). Your body then repairs these tears, and during that process, your muscles grow bigger and stronger.


But here’s the catch: muscle growth only happens if you give your body the right tools—enough protein, calories, and rest. Think of it like building a house: you need the right materials (protein), enough workers (calories), and time to actually build it (rest). If any of these are missing, your gains are going to be stuck in construction limbo. Now that we’ve got that out of the way, let’s talk about why you might not be building muscle, even though you’re putting in the work.


1. You’re Not Eating Enough

Here’s the deal: building muscle requires energy. Like, a lot of energy. If you’re not eating enough calories, your body doesn’t have the fuel it needs to repair and grow those muscles. You could be lifting like a beast, but if you’re eating like a bird, your gains are going to be as elusive as a Wi-Fi signal in the middle of nowhere. The fix? Eat more. Focus on nutrient-dense foods like lean meats, eggs, whole grains, and healthy fats. And yes, that means you might need to ditch the “I’ll just have a salad” mentality.


2. You’re Not Eating Enough Protein

Protein is the building block of muscle. Without it, your body is basically trying to build a skyscraper out of toothpicks. If you’re not getting enough protein, your muscles won’t have the materials they need to grow.


Aim for at least 1.5-1.8 gram of protein per kilogram of body weight per day. So, if you weigh 80 kg, you should be eating around 120-145 grams of protein daily. And no, that doesn’t mean you have to live off chicken breasts and protein shakes. Get creative—Greek yogurt, beans, tofu, and even peanut butter can help you hit your protein goals.


3. You’re Not Lifting Heavy Enough

If you’re still curling the same 10-pound dumbbells you started with six months ago, it’s time to level up. Your muscles need to be challenged to grow. That means lifting heavier weights over time (this is called progressive overload). If you can easily do 12-15 reps without breaking a sweat, it’s time to increase the weight. You should be struggling by the last few reps—like, “I might cry” kind of struggling.


4. You’re Not Resting Enough

Here’s a hard truth: your muscles don’t grow in the gym. They grow when you’re resting. If you’re hitting the gym every single day without giving your body time to recover, you’re basically spinning your wheels. Make sure you’re taking rest days and getting enough sleep (7-9 hours a night). Your muscles need time to repair and grow, and that only happens when you’re chilling on the couch or snoozing in bed.


5. You’re Doing Too Much Cardio

Cardio is great for your heart and overall health, but too much of it can interfere with muscle growth. If you’re running marathons or spending hours on the elliptical, you might be burning through the calories and energy your body needs to build muscle. That doesn’t mean you have to quit cardio altogether. Stick to 2-3 sessions a week, and focus on shorter, high-intensity workouts instead of long, steady-state cardio.


6. You’re Not Consistent

Building muscle is a marathon, not a sprint. If you’re only hitting the gym once a week or skipping workouts because “Netflix called,” you’re not going to see results. Consistency is key. Aim for 3-5 strength training sessions a week, and stick to a plan. Randomly switching up your routine every week might make you feel like a fitness guru, but it won’t do much for your gains.


7. You’re Not Tracking Your Progress

If you’re not keeping track of your workouts, how do you know if you’re actually making progress? Writing down your weights, reps, and sets can help you see if you’re improving over time. Plus, there’s nothing more satisfying than looking back at your notes and realizing you’ve gone from struggling with 10 kg dumbbells to crushing 20s like a boss.


The Bottom Line

Building muscle takes time, effort, and a little bit of patience. It’s not about being perfect—it’s about being consistent and giving your body what it needs to grow. So, eat enough, lift heavy, rest well, and don’t forget to celebrate the small wins along the way.

And hey, if all else fails, just remember: even Arnold Schwarzenegger started somewhere. Now go lift something heavy (and maybe eat a steak while you’re at it).

P.S. If you found this helpful, share it with a friend who’s also struggling to build muscle. Gains are better when you’ve got a gym buddy.
