The endless cycle of bulking and cutting is exhausting. You spend months getting strong but fluffy, then months getting lean but weak and hungry. Gaintaining offers a way out, a method to build quality muscle year-round without the baggage. This guide explains exactly how it works and if it's the right fit for you.
To answer the question 'is gaintaining a waste of time' directly: no, for most people, it's the smartest and most sustainable way to build a physique you're happy with year-round. It’s the antidote to the frustrating bulk-and-cut cycle that leaves you feeling either fluffy or flat for half the year.
Gaintaining is the process of building muscle by eating at or very slightly above your maintenance calories. We're talking a tiny surplus of 100-200 calories per day. This provides just enough extra energy to fuel muscle repair and growth (hypertrophy) without spilling over into significant fat storage.
Think of it as a slow, controlled lean bulk. Instead of force-feeding yourself 3,500 calories to gain 2 pounds a week (where at least 1 pound is fat), you eat 2,600 calories to gain 0.5 pounds a month, almost all of which is quality muscle tissue.
You might also hear terms like 'maingaining' or 'body recomposition'. They are all variations of the same idea. Maingaining is typically eating right at maintenance, while gaintaining implies the small surplus. Body recomposition is the outcome: losing a little fat while building a little muscle, resulting in a more muscular and defined physique at the same body weight. For our purposes, we'll treat them as the same strategic approach.
This method prioritizes quality over quantity. It accepts a slower rate of muscle gain in exchange for staying lean, strong, and feeling good all the time. No more packing away your favorite jeans during a bulk or feeling too weak to hit your lifts during a cut.

Track your food and lifts. Watch your body change without the fluff.
If you've been lifting for a while, you've been told the classic bulk-and-cut cycle is the only way. The problem is, for the average person who just wants to look and feel good, it's an incredibly inefficient and mentally draining process.
Here's the reality of a traditional bulk. You eat in a large surplus of 500+ calories. The scale goes up fast, which feels great. Your lifts get stronger. But for every pound of muscle you gain, you also gain about a pound of fat. After 4-6 months, you're strong, but you've lost all your definition. You feel soft and don't like how you look in the mirror.
So, you start a cut. You slash your calories by 500 or more. The first few weeks, fat comes off. But soon, the hunger kicks in. Your energy levels tank. Your lifts start going down, and you worry about losing the muscle you just worked so hard to build. After 2-3 months of misery, you're lean again, but you're also smaller and weaker than you were at the peak of your bulk.
You spend 70% of the year either feeling fat or feeling weak. You only enjoy your physique for a few months before you have to start the cycle all over again. It's a physical and psychological rollercoaster. Gaintaining breaks this cycle. It's a single, consistent approach that you can stick with for years, making slow but permanent progress.
Gaintaining requires more precision than a classic bulk, but the payoff is immense. It's not complicated, but you have to be consistent. Follow these four steps.
A successful gaintain depends on knowing your Total Daily Energy Expenditure (TDEE), or maintenance calories. This is the number of calories you need to eat to maintain your current weight. A simple starting point is to multiply your bodyweight in pounds by 15.
This is just an estimate. For the next two weeks, eat this number of calories every day and weigh yourself each morning. Take the weekly average. If your average weight stayed the same, you've found your maintenance. If you lost weight, add 200 calories. If you gained weight, subtract 200. This is your true maintenance number.
Once you have your maintenance, the math is simple. Add 100-200 calories. That's your new daily target. For our 180-pound person with a 2,700-calorie maintenance, the gaintaining target would be 2,800-2,900 calories.
Next, set your protein. This is non-negotiable. Aim for 0.8 to 1.0 grams of protein per pound of bodyweight.
Fill in the rest of your calories with fats and carbs. A good rule of thumb is to set fat at 25% of total calories and let carbohydrates make up the remainder. This ensures you have enough fat for hormonal function and enough carbs to fuel your workouts.
Eating in a tiny surplus won't do anything if you don't give your muscles a reason to grow. The magic of gaintaining happens when you combine that small energy surplus with a powerful training stimulus. This is called progressive overload.
Progressive overload means continually making your workouts harder over time. The simplest way to do this is by adding a little weight to the bar or doing one more rep than last time.
This slow, measurable progress is the signal your body needs to use those extra 100-200 calories to build new muscle tissue. Without it, those calories will just become fat.
Gaintaining is a game of inches, not miles. You cannot 'intuitively eat' your way through it. The margin for error is too small. You must track three things:
If your lifts are going up and your weekly average weight is increasing by 0.25-0.5 pounds per month, you are succeeding. Trust the process.

Track your food and lifts in one place. See the proof you're getting stronger and leaner.
Gaintaining is a powerful tool, but it's not the right strategy for everyone. Being honest about your training experience and current body composition is key to deciding if it's right for you.
This is for you if:
This is NOT for you if:
You can expect to gain about 0.25 to 0.5 pounds of lean body mass per month. This is much slower than a traditional bulk, where you might gain 2-4 pounds a month, but remember that half of that bulk weight is fat that you'll have to lose later.
Yes, this is called body recomposition. It is most common in beginners, people returning to lifting after a long break, or those who are overweight and new to training. For them, eating at maintenance while lifting heavy and eating enough protein can achieve both goals simultaneously.
This can be a great sign! If your body weight is stable but your lifts are consistently going up and your clothes are fitting better, you are likely achieving body recomposition. You're swapping fat for muscle, which is the ultimate goal. Trust your lift numbers and measurements over the scale.
Yes, it is non-negotiable. The target window of a 100-200 calorie surplus is too small to estimate accurately. A day where you accidentally eat 500 calories over is a day you're bulking, and a day you eat 300 under is a day you're cutting. Precision is the key to making this work.
Think of gaintaining as a long-term lifestyle, not a short-term diet phase. You can and should continue this approach for as long as it's working-meaning, as long as you are making slow and steady progress on your lifts and seeing positive changes in your physique.
