Newbie Gains: What They Are, How Long They Last & How to Maximize Them

I remember the sweet smell of newbie gains.

When progress was fast, and a new plate on the bar was something that just happened on a weekly basis.

But everything comes to an end, including this best of gym times.

In this article, I’ll talk about what newbie gains are, how long you can expect to enjoy them, and how you can make the most of yours while they last. And much more.

Introduction to Newbie Gains

If you’re new to lifting weights, you’re special. Even more special than your mom told you.

You may not realize it, but in your first few months of training, you can see some of the biggest gains you’ll ever have in the gym.

Your strength skyrockets. Your body starts changing. Exercises that felt awkward click.

You add weight to the bar almost every week.

This is the mythical phase called newbie gains.

And yes, they’re real.

However, they don’t mean you can do random stuff in the gym, eat crap, stay up all night, and still build an amazing physique.

But they do mean that, during this precious time, your body responds as it never will again, because lifting heavy things is something it has never done before.

If you take advantage of it, your newbie gains period can give you a huge head start.

If you don’t, it can strand you on a plateau sooner than necessary.

What Are Newbie Gains?

Newbie gains are the strength and muscle size improvements beginners experience when they start lifting weights.

When you’re new to lifting, your body gets better fast.

• You can go from struggling with squatting the bar to squatting 50 kg (100 lb) or more with confidence, in a few weeks. You might add small plates to your bench press every workout.
• You and everyone around you notice that your physique looks different within a few months. Different in a good way.
• Your clothes don’t fit as they should, but this time they’re not tight around the waist, but around your shoulders.

All this happens because the stimulus of strength training is fresh. Your body hasn’t adapted to it yet.

Your muscles and nervous system and joints are all learning and improving at the same time.

That combination makes your gains excitingly fast.

How Long Do Newbie Gains Last?

There isn’t any universal newbie gains countdown timer. There are no studies that have quantified exactly how long they last.

If I had to pull a timeline out of my hat, I’d say you’re likely to enjoy your most noticeable gains during the first few months of your training.

As long as that training is consistent and you’re not eating too little.

My experience tells me that they can continue for at least the first year, depending on your starting point.

But it’s a very blurry timeframe. You don’t suddenly wake up after 12 months and discover that your beginner gains have expired.

How long they last depends on many things. Like:

• How consistently you train
• Whether you follow a good beginner program or do random things in the gym
• Your nutrition
• Your sleep and recovery
• Your genetics
• Your sporting or lifting background

Someone who trains sporadically for two years can still have plenty of beginner progress available, while someone who is extremely dedicated and does everything by the beginner lifter handbook for a year can move through the newbie gains stage faster.

My best tip: Instead of worrying over how many months you have left, pay attention to what’s happening in the gym right now.

When you’re just starting, you’ll probably be able to add reps or weight almost every workout.

Soon enough, progress becomes slower. That doesn’t mean you’re doing something wrong, just that you’re no longer a complete beginner. You might progress every few weeks instead of from workout to workout.

Later still, meaningful gains can require months of hard training. When you’re at that point, your newbie gains are officially over.

You can’t hold onto them forever. You don’t want to.

That slowing down happens to everyone. It means you’re becoming more advanced and need to move on from beginner training to see your gains continue.

How Much Muscle Can You Build During Your Newbie Gains Phase?

I can’t say how much muscle you can gain. That depends on the same factors I mentioned above.

However, we have research here. It suggests that a typical untrained young man can add about 1–2 kg (2–4.5 lb) of lean mass during his first 8–12 weeks of training.

Again, lean mass isn’t the same as contractile muscle. Many studies use methods to measure muscle growth that include water and glycogen as well.

Also, most studies are on men, but we know that women actually build muscle just as well as men.² The difference is that they (often) start with less total muscle mass, so the absolute numbers will be smaller.

Here are some concrete examples (both weight and size gains) I dug up.

Newbie Gains Research

Study	Subjects & Study Length	Result
Franco et al.3	18 untrained young men, 8 weeks.	+1.0 to +1.5 kg (+2.2 to +3.31 lb) lean body mass depending on training group.
Lynch et al.4	Untrained young men and women, 12 weeks.	+1.54 kg (~+3.4 lb) lean body mass on average.
Mobley et al.5	Untrained college-aged men, 12 weeks.	Large variability: some added ~0.69 cm of vastus lateralis (a thigh muscle) thickness, while others gained almost nothing.
Holm et al.6	Sedentary men, 12 weeks.	Up to ~8% quad growth.
Vissing et al.7	Untrained young men, 12 weeks.	Thigh growth of 7–10%.
Abe et al.8	3 young men, 16 weeks.	Skeletal muscle mass as estimated by MRI increased 4.2 kg (~9.25 lb), fat-free mass increased 2.6 kg (~5.7 lb).

That last study had some massive gains, but I wouldn’t consider them the expected result because it only had three participants. I think the more interesting result is that different measurement methods can give very different answers.

Perhaps the most reliable numbers we have, so far, are from a 2020 meta-analysis, which found an average muscle gain of 1.53 kg (~3.37 lb), with a 95% confidence interval of 1.30–1.76 kg.⁹ We’re talking young men and studies lasting two weeks to one year.

No women here, but I’d expect the absolute numbers in kg to be lower, but the relative gains to be similar.

Studies that zero in on a single muscle instead of looking at full-body growth often see 5–10% increases in muscle size within 10–12 weeks.

So, a beginner who notices some nice newbie gains in their thighs or arms within three months isn’t unusual, and that’s backed by plenty of research.

But Individual Variation Is Huge

This is probably my favorite study for illustrating the differences in gains between lifters.¹⁰

The researchers put 585 untrained men and women through 12 weeks of biceps training and measured their gains with MRI.

Changes in muscle size ranged from -2% to +59%.

Yes, 59% gains in some biceps in 12 weeks.

The variation in strength increases was also ginormous, from 0% to +250% for 1RM.

Notice that a few of the participants actually lost muscle?

That’s because people respond differently to strength training. Some gain fast, others slow.

We call those high responders and low responders.

Although I should mention that many studies don’t control what the participants eat and stuff like that, so the differences don’t have to be all genetics.

Also, those results don’t mean that someone can increase their total muscle mass by 59% in that timeframe. This study only looked at one small muscle, and the muscle gained wouldn’t look like much if you measured up the same amount of beef at the meat counter.

What Does This Mean for Your Entire Newbie Phase?

If I take the results from studies and mix in some observations from decades of experience, I’d say that in the:

• First 3 months: ~1–2.5 kg (2.2–5.51 lb) of new muscle? Very doable.
• First 6 months: ~2–4 kg (4.4–8.8 lb) sounds like a reasonable ballpark.
• First year: 3–6 kg (7–13 lb) of muscle would be a very successful first year for a man. Perhaps ~2.5–4 kg (5.5–8.8 lb) for a woman.

Most strength-training studies last ~8–24 weeks, tops, so the longer the period we’re talking about, the more we’re guesstimating.

Someone with great genetics, a large frame, or who starts with very little muscle might gain even more.

And someone dieting hard, sleeping poorly, or being 70+ would likely gain less.

You can absolutely gain more scale weight than the numbers above indicate, but it won’t all be muscle.

Why Beginners Grow So Quickly

I’m pulling out the elementary school examples for this one. Mostly to make it easier for myself.

Let’s take someone who has never done any weight training and have them hit the gym three times a week.

Up until now, their muscles had very little reason to grow. Then, poof, they’re being exposed to mechanical tension – the big driver of growth – every other day.

That’s a new and very potent signal for muscle growth.

An advanced bodybuilder is in a different situation entirely.

They’ve already spent years going at it in the gym and are already much closer to whatever potential for building muscle their genetics has decided upon.

At that point, creating the stimulus for even more growth is quite the challenge.

You, as a beginner, are still far away from that ceiling.

That’s why you make progress with training that an advanced lifter would barely respond to.

Can You Waste Your Newbie Gains?

What if you’ve been doing some half-baked training for months or years, not really exerting yourself in the gym, and therefore not making much progress?

Have you wasted your newbie gains?

No, you haven’t.

I’ve seen this numerous times. Once someone who has been a “gym-goer” for years but hasn’t really made the effort to improve starts to make that effort, starts to train hard, starts to eat properly, the newbie gains come like a letter in the mail.

Even if they aren’t newbies on paper, if you only look at the time spent in the gym.

Once the effort is there, the results are, too. You reached a plateau sooner than necessary, but you can get past it pretty easily, too.

Can You Get Newbie Gains Again?

Sometimes, yes.

If you’ve trained before and quit, even for a long time, and then return, you’ll experience a version of newbie gains again.

This is called muscle memory.

There are many more or less complicated theories about how muscle memory works, but the truth is that we don’t really know for sure.^{15 16}

What we do know is that your body can regain any muscle (and strength) it’s lost much faster than it took to build it the first time.^{17 18}

So if you used to lift and fell off, you’re not starting from zero. You’ll bounce back quickly, probably much quicker than you expect.

You can also get newbie-like gains if you switch to a completely new type of training, at least when it comes to strength.

For example, if you’ve been training for years but only used machines and then suddenly start barbell training, your strength in those lifts will increase as if you were a beginner.

Because “strength” is more than physical strength. It’s also a skill.

But true first-time newbie gains are unique. That’s why you should take advantage of the opportunity.

How to Maximize Your Newbie Gains

The best way to maximize your newbie gains is to keep things simple. And then do those simple things well, over and over.

What you don’t need is a complicated six-day split or advanced intensity techniques.

And you don’t need to train until you burst a blood vessel every workout.

You need the basics.

• Train each major muscle group at least twice per week. You grow equally well training everything once per week, but as a beginner, you want to learn how to train, and the best way to do that is to practice. Three full-body workouts per week is probably the sweet spot.
• Focus on compound movements, exercises that involve several joints and muscle groups. Like squats, presses, rows, deadlifts, and pulldowns. Add isolation work if you have time and energy.
• Use progressive overload. That means gradually doing a little more or working a little harder over time. More weight, more reps, more sets. But don’t go overboard and increase everything all the time. You don’t need to set personal records every workout (although you very well might as a newbie).
• Learn good form. Full range of motion, controlled reps, stable positions, and no swinging to lift heavier just for the sake of lifting heavier.
• Eat enough. Calories, protein, fats, and carbs if you want. A good target for protein is around 1.6 to 2.2 grams of protein per kilogram of body weight per day (0.7–1 g per lb/day). You can diet for weight loss if you’re heavy, but eating too little will hamper your muscle gains.
• Sleep. Seven to nine hours. It just works.

And the most important thing: stay consistent. Boring consistency beats random spurts of enthusiasm 100% of the time.

Track Your Training

Tracking your workouts is one of the easiest ways to outgain most other beginners.

Write down what you do. Exercises, sets, reps, and weights.

Guessing your progress is a bad strategy. Measure it.

If you’re relying on memory, managing progressive overload becomes near impossible, because your memory is terrible. Sorry, but it just is. And so’s mine. No one can remember every set and rep they did on leg day last Tuesday.

Your workout log will tell you exactly what you need to beat.

If you benched 75 kg × 10, 9, 8 reps last week, your mission is obvious this week.

Maybe you get 77.5 kg. Maybe you get 75 kg × 10, 10, 9 reps.

Both are progress.

Stack these tiny improvements over dozens of exercises and hundreds of workouts, and you’ll have transformed your physique.

So, How Do You Track It?

You could write everything down on paper. That’s how we did it in the ’80s, and it still works today.

In fact, we have a free printable workout log you can use and relive the golden analog days.

But the best way to track your training is with our workout log app. It’s called StrengthLog, and it’s available for both iOS and Android.

It’s free to use, and it has no ads.

We do have a premium version that gives you advanced statistics, more built-in programs, and other exciting stuff, but as a newbie, you don’t need it.

With the free version, you get unlimited workout logging and all the tools you need to take you through your newbie gains and beyond.

Three Training Programs for Newbie Gains

As a beginner, you shouldn’t take an advanced lifter’s program and copy it.

Someone with 10 years of bodybuilding under their weight belt needs a lot more volume and specialization than you do.

Their routine is designed for their body and their goals.

You don’t need it yet.

Also, you don’t need to reinvent the wheel. I strongly suggest you follow a proven beginner program instead of making things up as you go.

Here are three great beginner programs that’ll set you off on the right path.

All are free to follow in the StrengthLog app.

1. Beginner Strength Training Program

With our Beginner Strength Training Program, you train two or three full-body workouts per week.

2. Bodybuilding for Beginners

If bodybuilding is your game, this program is your perfect starting point. Three workouts per week focused on one thing: building muscle.

3. Beginner Barbell Program

Perfect if you train at home without a full gym setup, or if you simply want to get started with the most perfect piece of training equipment ever invented: the barbell.

Start Your Newbie Gains in StrengthLog

These are just three of the many excellent beginner programs in our workout tracker app.

We have many more – feel free to browse them before you decide:

>> Strength Training Programs for Beginners: The 15 Best to Get Started.

But I picked these three because they really are some of the most effective and most accessible. And popular.

They are free to follow and ready to start right away.

The app makes it super easy to keep track of your weights and reps so you can focus on the actual lifting.

Final Rep

Newbie gains are your early reward for doing something new and challenging.

They can help you build muscle faster than you thought possible and fall in love with training.

They aren’t permanent. But the habits you build while they last can carry you for a lifetime of gains.

Thanks for reading, and good luck with your training.
