Many people experience frustration when trying to build muscle. You might be hitting the gym regularly, eating enough protein, and even tracking your macros, yet you still donât see the noticeable gains you expect. If this sounds familiar, youâre alone. Many people ask, âWhy am I not gaining muscle?â and âhow to hit your macrosâ when they hit a plateau in their training. This article will help you answer that question by uncovering common mistakes that lead to muscle-building roadblocks. Youâll learn to build muscle consistently and efficiently to avoid wasted effort and see noticeable gains.
Goldi AIâs calorie tracker can help you reach your muscle-building goals by accurately tracking your calorie and macro intake. This will help you avoid common mistakes that slow progress.
Why Am I Not Gaining Muscle? 14 Training & Nutrition Tweaks That Work

1. Your Training Is Random: The Importance of Structure and Consistency
Jumping from exercise to exercise without a plan wonât get you anywhere. âRandom exercises get you random results,â says Tonal coach and certified personal trainer Joe Rodonis. Gaining strength and muscle results from progressive overload, or gradually increasing stress on your body through:
- Resistance
- Volume
- Time Under Tension
When youâre not planning your workouts, youâre likely not balancing out the time you spend on each muscle group or adding stress productively and progressively.
The Fix
The easiest way to ensure youâre achieving progressive overloadâin a way thatâs also safe and gradual so you wonât get injured or burn out too soon, is to follow a well-balanced program that fits your goals, works all your major muscle groups each week, and gets progressively challenging.
Consistent Variation
Once youâve picked your program, stick with it and be patient. âStay consistent for at least two if not four weeks,â says Rodonis. That doesnât mean your workouts will be boring, though. Programs can be varied without being random. From week to week, slight variations in exercise selection or rep range will keep you engaged while focusing on the larger goal.
The scientifically backed programs on Tonal check all the boxes, feature expert coaches guiding you every step of the way, and will safeguard you from lifting weights but not gaining muscle.
2. Youâre Underfueling: Why Eating Enough Is Critical for Muscle Gain
You might think you need to cut calories if youâre trying to get lean and see muscle definition. But eating too little isnât the way to go, either. âYou canât drive intensity if youâve got no gas in the tank,â says Rodonis. âHow can you build muscle if youâre depleting it of energy sources?â
The Fix
Instead of restricting calories or following a strict diet, try to include a mix of food groups such as vegetables, complex carbohydrates (whole grains, beans, and legumes), and, most importantly, ample protein. Protein is essential for muscle growth and should be consumed on workout and rest days.
Optimizing Protein Intake for Muscle Hypertrophy
Even though the recommended dietary allowance (RDA) for protein is 0.8 to 1 gram per kilogram of body weight per day, you should increase that number to see significant gains. A meta-analysis of studies has shown that if you want to gain muscle mass and strength, you should eat closer to 1.6 grams of protein per kilogram of body weight per day.
Protein Intake Recommendations
- Overall Health Maintenance: 1.0 - 1.2g protein per pound of body weight.
- Athletes & Muscle Gain: 1.3-1.5g protein per pound of body weight. The type of protein you include in your diet is essential. We recommend including a variety of protein throughout the week, including:
- Dairy (greek yogurt, eggs)
- Beef (steak, lean ground beef)
- Poultry (chicken breast)
- Seeds (hemp, chia, flax)
- Eggs (with yolk & without)
- Whey Protein Isolate: Each protein source includes a full spectrum of branched-chain amino acids, which are the building blocks of your highly sought-after muscle. If you havenât included foods with a complete amino acid profile in your diet, it could be another reason you canât build muscle mass.
3. Youâre Not Doing Enough Accessory Work: Why Muscles Need Support Too
Big compound lifts such as squats, deadlifts, and bench presses get a lot of attentionâand with good reason. These multi-joint exercises strengthen your bodyâs largest muscles, improve functional movement patterns, and boost metabolism by increasing lean muscle mass. But that doesnât mean you can forget about strengthening smaller muscles.
You might not do enough accessory work if you lift weights but do not gain muscle. âWhen weâre talking about building muscles, specifically in hypertrophy, you really want to target more isolation exercises,â says Rodonis.
If you need more evidence, Tonal members who performed more tricep-isolation work saw more significant improvements in their bench press strength.
The Fix
Continue compound exercises, but add accessory moves to round out your training. Along with supercharging your gains in specific areas, accessory work also improves your performance in compound exercises by building supporting muscles. One way to do this is by incorporating isolation exercises to complement your primary lift in a workout.
For example, if my main lift is a deadlift, Rodonis suggests adding barbell hip thrusts to isolate the glutes.
4. Youâre Rushing Your Reps: Why Tempo is Key for Muscle Growth
You canât hurry through your workouts when youâre looking to see significant increases in muscle size. âHypertrophy is about mechanical tension,â says Rodonis. âIâm more concerned about time under tension, meaning I feel the weight the entire way down and the entire way up.â
In one study, participants who performed leg extensions at a rate of six seconds up and six seconds down saw more significant increases in muscle protein synthesis than those who did their reps at a faster tempo of one second up and one second down.
The Fix
Slow down! It can be easy to feel like youâre doing more work by pushing hard and fast, but youâll see more hypertrophy gains by increasing your time under tension. Tonal measures this metric to compare how much time you spend under tension in each workout. Eccentric Mode on Tonal adds resistance in the lowering phase of an exercise, increasing tension and slowing down your pace.
Eccentric training has also been shown to increase muscle growth. Donât rush your rest periods, either. In one study, participants who rested three minutes between sets saw a more significant increase in muscular strength and size than those who rested for just one minute.
5. Youâre Not Lifting Heavy Enough
According to Rodonis, if youâre trying to build muscle, you should be lifting heavy enough to feel like you could do no more than two additional reps (known as reps in reserve) when you finish your set. âItâs not hitting failure, but if you feel like you could rip out another 5, 8, or 10 reps, itâs way too light,â he says. âA lot of people underestimate what they can do and they lift a little bit too light.â
The Fix
Figuring out how much weight to use in a specific exercise to get close to failure can be confusing. One method is to figure out your 1-rep max for each exercise (the most you can lift for a single rep) and then work at 70 to 80 percent of that weight, the recommended range for hypertrophy training.
Practical Intensity Assessment Through Rep Estimation
A 1-rep-max test can be very intense and may require a spotter, so you can also follow Rodonisâs guidelines and estimate how many additional reps you could do at the end of your set. Be honest with yourselfâif your reps feel effortless and you think you could crank out a bunch more, you likely need to go heavier.
Tonal takes the guesswork out of the equation by giving you personalized weight recommendations for each exercise and set. As you strengthen and you estimated 1-rep max increases, Tonal will keep increasing your resistance to maintain the challenge.
6. Youâre Not Getting Enough Sleep: Recovery Starts with Zzzs
When you break down your muscles during a challenging workout, you need enough sleep to recover and work out at full intensity. âPeople who consistently get less than six hours of sleep have an elevated heart rate and are more prone to injury,â says Josh Clay, a certified strength and conditioning specialist and Fitness Programming Specialist at Tonal.
The Fix
While you should be aiming for seven to nine hours of sleep, you must also get enough deep sleep. Thatâs where the recovery magic happens. âThe only thing you can do is get more overall time in bed because deep sleep and REM sleep are a percentage of total sleep time,â says sleep specialist Dr. Meeta Singh, a physician and psychiatrist.
Optimizing Sleep Environment
âYou canât control your stages of sleep, but you can ensure you set aside enough time for sleep.â To get the most out of your time spent in bed, Singh suggests keeping your bedroom temperature around 65 degrees and making your room as dark as possible, either with blackout shades or an eye mask.
Clay recommends turning off electronics at least one hour before bed and consuming your last meal at least two hours before bedtime. âIf youâre eating super close to bedtime, your body is still trying to digest that food,â he says.
Naps as Strategic Recovery
âThatâs going to inhibit your ability to fall asleep and stay asleep.â If youâre having trouble getting enough sleep at night, Singh says thereâs nothing wrong with napping during the day. âBank sleep when you can, get well rested when you can, and use naps to play catch up when you canât, because we all have limitations.â
7. Your Form is Off: The Importance of Proper Technique for Muscle Growth
Just going through the motions in your lifting and not focusing on your form can easily result in lifting weights but not building muscle. âI think of building muscle like a loaded stretch,â says Rodonis. âI want to feel the elongation of the muscle and then I want to pull through the entire range to complete [the lift].â
According to one study, lifting with proper form through your entire range of motion is more effective at building strength than working in a smaller range of motion.
The Fix
Rodonis says focusing on mobility before adding resistance can help with form. If you have limited mobility, try adding an extended warmup to your workouts, targeting the areas you plan on working (like the hips and hamstrings for deadlifts), or use your off days from lifting to focus on stretching.
Improving your range of motion will help you get the most out of your lifts. Just like an experienced personal trainer, Tonal offers real-time form corrections as you work out in two ways:
- Form Feedback from Tonalâs cables measures your pace, range of motion, balance, symmetry, and smoothness as you lift
- With cutting-edge visual technology, Smart View allows you to see yourself lift and watch video playback of your workouts to improve your form.
8. Youâre Overtraining: More Isnât Always Better
More isnât always better when it comes to lifting. âIf you do too much, youâre going to get diminishing returns,â says Rodonis. âYour body is under too much stress, so it canât recover properly and you wonât see growth.â
Think of your muscles like batteriesâif you work legs on a Monday, your legs wonât be 100 percent fully charged by Tuesday, so you wonât be able to go as hard on another leg workout.
The Fix
Build up to at least 10 sets per muscle group weekly for hypertrophy. âYou can spread that out,â says Rodonis. âIf Iâm hitting chest, I can do 6 sets of chest on Monday and another 6 sets on Thursday and Iâve hit my hypertrophy goal for chest.â He adds that itâs best to give each muscle group 48 hours of rest in between workout days and keep hitting your protein targets.
Strategic Muscle Group Partitioning
That doesnât mean you canât work out more oftenâjust make sure youâre splitting up the days youâre working on specific body parts or pushing and pulling muscles. In Rodonisâs program, Divide and Conquer: Level Up, youâll work out five days per week, but the muscle group splits ensure you wonât overload one area.
9. Youâve Been Using the Same Workout for Too Long
Building muscle is simply the process of the body reacting to increased stress. When you put stress on your muscles in the gym, they grow more significant to cope with the stress. The body is quick to adapt to any changes, including your workout. Once your body adjusts to your workout routine, it will not need to build more muscle or get stronger.
Adaptive Training
You have to change. You should change your workout when you stop getting more substantial or heavier or after about 8-10 weeks. Donât change if youâve been doing my workout for 12 weeks and youâre still growing. Everyone is different. If youâre still growing, stick to it. We have plenty of great workouts on this site for all experience levels.
10. Youâre Drinking Too Much Alcohol: The Effects of Booze on Muscle Growth
Not to be a buzzkill, but those beers you had with your friends over the weekend or the two glasses of wine you âneedâ to relax at the end of a long day arenât doing your gains any good. âItâs empty calories, for one,â says Rodonis, âand two, it messes with your sleep and deteriorates your performance.â
Strategic Alcohol Reduction
Along with adding calories without any nutritious value, alcohol inhibits muscle protein synthesis (even if you are strength training) and spikes the stress hormone cortisol.
The Fix
Eliminating alcohol is your best bet for optimizing your gains. Cutting your intake is a good place to start if thatâs not practical.
Avoid drinking before bed as alcohol can affect your sleep, and donât drink on an empty stomach. Eating before drinking will also slow the absorption of alcohol.
11. Youâre Not Drinking Enough Water
When you donât drink enough water and stay well hydrated, you starve your muscles of a critical nutrient. Water is key in transporting nutrients that form protein and glycogen for muscle growth. It is also needed by nerves that control muscles. Staying well-hydrated should be your priority when fine-tuning your health.
How much water should you drink to gain muscle? A good guideline is 50 mL or 1.7 fl. oz. per kilogram of body weight consumed throughout the day. Or aim for 16 cups or a gallon of water.
Pro tip
A gallon might seem like a lot, but it should be doable if you drink 2 cups with each meal and snack. Try to get your water intake done earlier in the day so youâre not waking up to pee at night. Also, keep in mind that alcohol is dehydrating and suppresses the central nervous and immune systems.
Alcoholâs Interference
Studies have shown that when you drink alcohol, it interferes with protein synthesis pathways as well. This is all bad news if your goal is muscle building. Skip the drinking sesh with friends and opt for something healthier. If you have a few drinks, pay attention to your nutrition to make up for the damage.
12. Using Proprietary-Blend Filled Supplements: Why You Should Read Labels
Stay away from supplements with proprietary blends. These blends make it impossible to know precisely what you are ingesting and eliminate your ability to pinpoint how effective specific ingredients are within your body. Most, if not all, supplements with proprietary blends underdose the actual ingredients you need to improve your performance to save money.
Undermined Efficacy
They sprinkle ingredients proven to increase muscle mass and strength, such as Beta-Alanine, Citrulline Malate, and Creatine. So, instead of getting stronger, optimizing recovery, or improving endurance, youâre just wasting your money since youâre not getting enough ingredients to make a difference.
Beyond Generic Supplements
The bottom line is, donât be most people. You should care about whatâs in the supplements youâre taking because you wouldnât be looking at taking nutritional supplements in the first place if you didnât genuinely care about yourself and your well-being. Take the extra time and research to ensure your products are transparent, clinically dosed, and made with proven ingredients with no blends. Itâs worth it.
13. Your Post Workout Nutrition Sucks: The Importance of Recovery Nutrition
Your post-workout shake/meal is arguably the dayâs most important meal. When you finish your workout, your muscles cry out for nutrients lost during training. Your protein levels are down, creatine levels are down, and glycogen is depleted. Most people think a simple whey protein shake is all thatâs needed after your workout.
Optimized Post-Workout Nutrition
This is not true. While a protein shake is better than nothing, it still falls short of a good post-workout shake. Hereâs what would be better: a Shake containing 30-40g of whey protein powder, 5g of creatine, 60-70g of dextrose. 1 hour later: A well-rounded meal containing protein, complex carbs, and fats.
Insulinâs Anabolic Advantage
You see above Iâve pimped out your post workout shake by adding dextrose and creatine. Dextrose is the simplest of simple carbohydrates. Studies have shown that taking dextrose in these doses creates a vast insulin spike in the body. Insulin is a highly anabolic hormone and helps move nutrients quickly throughout the body.
This means that the creatine, protein, and BCAAs are quickly absorbed into muscle cells, where they are needed for muscle repair.
14. Lack of Accountability and Poor Planning: Why You Need Structure to Gain Muscle
The final and probably biggest thing preventing you from seeing results is a lack of planning. If you want success, plan your meals and workouts. Building a house without a blueprint and the right materials is challenging. The same thing goes for your body. Plan your meals and workouts for one to two weeks to ensure youâre getting adequate nutrition, that your workouts are enough to stimulate growth, and that youâre allowing for rest.
Disciplined Consistency
Recording your workouts and nutrition is key. Find workouts that you enjoy. I enjoy a blend of powerlifting and strength training assistance work. Find something you like thatâs consistent with your training goals. Being âmotivatedâ to go to the gym isnât enough because it thrives on your emotions and the ups and downs in your life. Instead, focus on a plan, be disciplined with consistent workouts, eat a healthy diet, and get after it.
