What’s the best age to build muscle – and are you doomed if you’re outside that range?
Today, we will look at how age and muscle building work together, what factors you can change, and the burning questions around age. To give you a hint – it’s more interesting than you think, and the golden oldies amongst us aren’t out of luck just yet.
How Age and Muscle Work Together
Muscle building is a process that starts the moment you’re born, and it continues throughout your life until you either:
- Stop training for muscle growth, or
- You reach your genetic limit of how much you can maintain
Age and muscle-building are related to hormonal changes.
Age-related loss in testosterone levels is associated with muscle breakdown and reduced muscle building, drastically limiting your muscle growth.
These levels change as we age – peaking at around 18-21 years old, staying high through the 20s, and then dropping off around 35 (on average). This produces age-related muscle and strength loss, respectively, known as sarcopenia and dynopenia.
For women, the timelines are similar, but the later effects also have to engage with poor estrogen levels. Menopause is a complex hormonal process that can affect muscle-building and health in the bones, female sex hormones, and the mammary glands of the breasts.
The way we age has a huge impact on how our health and physique change. While we can’t stop you from aging, a proper lifestyle impacts how you age.
The Best Age to Build Muscle
The best age to build muscle is between 16 and 30 – these are the years when testosterone levels are highest in men. These are the best years for women, too, as the body is most receptive to nutrient uptake and muscle building while having greater hormonal stability and other anabolic hormones.
The balance of hormones related to muscle building and muscle breakdown is tilted towards growth.
You’re also more healthy and responsive in the nervous system, which means better training throughout and a better total response to your training. It means better performance, which means better results.
During these years, you’ll also have a better medium-term response to changes in body fat, for example.
This does apply differently to women in bodybuilding. However, getting very lean is probably a bad idea before you’re 25 due to the hormonal and reproductive damage that very low-body fat has on women’s health.
Is Young Adulthood the Best Time to Build Muscle Mass?
Young adulthood – from 16 to 25 – is one of the best times for training where your body is most receptive to growth and is still developing in other areas. There is more plasticity in the body than later on when things are more set in place.
Age 18 is the earliest access most people have to intense and routine training and is the point at which muscle-building processes are at the highest level.
This is also an overlap between the earlier development of women (15-25) and the later development of men (18-30), making it a great time.
Young adulthood then has the physiological benefits, and it’s why many elite athletes – who have excellent technique and a very long training history – still peak in their early-mid 20s.
Recovery and hormonal health are the most robust here, so you can train harder and recover better.
However, there is more to training and results than age and testosterone – and many people find that the overlap between biological factors and behavior factors overlap in the mid-20s and afterward.
It’s no surprise that many 16 to 25-year-olds aren’t eating, training, or living in a way that maximizes their results.
Can You Build Muscle Over 30?
While you will have lower testosterone levels in your 30s than 20s, you can still build amazing amounts of muscle over 30. Your age is not a reason to give up – it just requires a change to how you train.
The main difference between muscle-building in your 20s and 30s is that it becomes more difficult and slower. However, it is more important in your 30s to remain active and be only a few %-points harder than younger people.
Age is no reason not to put time into your fitness, muscle mass, and body transformation.
The pace may be slightly slower as testosterone levels are lower. Still, you’ll find that maturity in your training style, recovery, and other areas can easily make up for these deficits in real terms.
Being able to eat and train properly, to get better coaching and nutritional support will have more impact on muscle gains than the difference between being 28 and 31. The important part is this: don’t forget that age is just one factor, and you have control over many others!
Age and Muscle Mass FAQ
Is Bodybuilding Impossible Over 30?
You can get into bodybuilding at any age; you might not become Mr. Olympia.
You can build more muscle and get into great shape at any age, but you may want to adjust your expectations – you’re going to be improving slightly slower than you would in your 20s.
The real difference is that you’re just going to need to train smarter. Guys over 30 need to account for lower testosterone levels than they might if they started at 19. However, getting active in your 30s is a good idea and one of the best ways to protect your testosterone levels and improve muscle growth.
What’s the Perfect Age for Bodybuilding?
The perfect age for competitive bodybuilding is anywhere between 16 and 35.
Testosterone peaks around 16-21, while you still need years of maturity to build the muscle mass and round out your physique, meaning you should be competing at your best between 25 and 35, depending on when you start.
Your 20s are the best time for training, but you probably won’t peak for ten years, as your training and physique will require long-term change, and your strategies will improve over time.
Other things like posing, conditioning, and stage-day tactics come with time and experience.
35 is the upper limit to our ‘perfect age for bodybuilding’ because it is when testosterone levels are typically dropping off most quickly. Of course, this differs from person to person, and you can continue to improve for a long time if you’re not at your natural limit by the time you reach 35.
Can You Still Achieve Muscle Growth with Age?
You are never too old to achieve muscle growth – at any age.
Even very old people (80+) can build muscle mass and improve their physical condition, But with severe caution.
You can build excellent amounts of muscle in your 20s and 30s, and it does drop off afterward, but you’ll always be able to improve somehow.
Bodybuilding is very visual, which means losing peak muscle mass can be a problem as you age.
However, you can continue to improve in areas like strength and skill with age. Being active in physique improvement and body transformation can improve testosterone levels when they’re usually starting to drop off.
If you’ve not been heavily involved in fitness before, getting into bodybuilding and muscle-building after 35 is an amazing way to restore your vitality and youth.
It’s a great way to combat hormonal decline, improve a wide range of health factors, and transform your body.
What Is the Best Age for Weightlifting?
As with any sport, starting sooner is better for weightlifting.
The best athletes started as young children, with a balanced and healthy amount of training, and a lot of variety with other types of exercise and sport – like gymnastics and athletics.
The best weightlifters started around age seven and began intense training in their teen years. This is a long-term development plan in countries where athlete development pathways are well developed and supported.
You’ll probably peak somewhere in your mid-20s, physically speaking, but the combined long-term development of good technique, neuromuscular efficiency, and strength all change based on how you train.
There’s no reason you can’t compete into your 30s if you stay healthy and develop sufficiently good strength and technique over your training career.
Masters weightlifting competitions start at age 35 and are bracketed every ten years so that you’ll always be competing with people vaguely similar in age.
What Age Does Guys Start Building Muscle?
You start building muscle the day you’re born and you only stop when you decide to stop training.
Developing muscle mass, strength, and power is part of the physical maturation process. You’re going to build muscle any time you’re exercising until you reach the maximum of your genetic potential.
Guys build more muscle mass during their teen years, and this peaks around 16-21 years old, when testosterone levels are highest, but growth isn’t split between growth and muscle gains.
The end of your teens and 20s is the easiest time for building the most muscle.
You can build muscle mass after this period. However, it does become progressively slower over time. Your hormones will decline over time, though you still have much control through training, nutrition, recovery, and other lifestyle choices/habits.
What is bodybuilding age limit?
While there is no upper age limit for bodybuilding, the activity is generally not recommended for individuals over the age of 60.
Bodybuilding takes a toll on the body, subjecting it to strain, impact and injury.
The older someone gets, the less able their bodies are to recover from these type of activities. Additionally, many of the drugs commonly used in bodybuilding can have negative side effects on seniors.
For these reasons, other forms of exercise are typically recommended for people over the age of 60.
Conclusion on Best age to Build Muscle
Building muscle is easiest from age 16 to 25, but that doesn’t mean it’s hopeless outside of this range.
It’s also important to remember that your hormonal environment results from how you live, and there are many other factors that you can use to recapture the best results – diet, sleep, supplementation, recovery, and proper guidance from a coach or nutritionist.
Age is the one training factor you can’t change, and it will require working with, working around, or just accepting.
The important thing is that you do what you can with the things you have control over: it would be perfect to start as a child and peak in your mid-20s, but most people don’t.
You can still build muscle over 30 – and there’s never a bad time to improve your physique, build better health, and get the confidence and mental benefits of fitness!
