Why Men Over 40 Struggle to Build Muscle And What To Do About It

“I Used to Be Able to Build Muscle Much Easier…”
It’s a conversation we have almost every week at Soma Fitness.
Men in their 40s often tell us:
• “I train as hard as I used to.”
• “I don’t seem to recover like I did in my 20s.”
• “I’m gaining fat more easily.”
• “I feel weaker than I used to.”
• “I look softer despite going to the gym.”
The frustrating part?
Most men assume it’s simply age and that there’s nothing they can do about it.
The reality is very different.
While building muscle after 40 can be more challenging, it’s absolutely possible when you understand what has changed and how to adapt your approach.
Why Building Muscle Becomes More Difficult After 40
Several physiological changes occur as we get older.
1. Loss of Muscle Mass Begins Earlier Than You Think
Most men begin losing muscle mass from their early 30s.
This process, known as sarcopenia, gradually accelerates with age.
Without resistance training, the average person loses:
• muscle mass
• strength
• power
• mobility
year after year.
This doesn’t just affect appearance.
It affects:
• metabolism
• energy levels
• posture
• injury risk
• long-term health
2. Recovery Takes Longer
In your twenties you could often get away with:
• poor sleep
• excessive training volume
• inconsistent nutrition
By your forties, your body becomes less forgiving.
Recovery capacity declines, meaning:
• soreness lasts longer
• injuries become more common
• progress slows if recovery is neglected
This doesn’t mean training less.
It means training smarter.
3. Stress Is Higher Than Ever
Many men over 40 are juggling:
• demanding careers
• business responsibilities
• mortgages
• young children
• ageing parents
Chronic stress elevates cortisol levels and can negatively impact:
• recovery
• sleep quality
• muscle-building capacity
• body composition
This is often one of the biggest hidden reasons men struggle to make progress.
4. Activity Levels Drop
Most men are far less active than they were 20 years ago.
Many spend:
• 8–10 hours sitting at a desk
• commuting
• attending meetings
• working from home
This often leads to:
• poorer posture
• reduced mobility
• decreased energy expenditure
• increased body fat accumulation
The Biggest Muscle Building Mistake Men Over 40 Make
When progress slows, most men assume they need:
• more workouts
• more exercises
• more intensity
In reality, many need the opposite.
The goal isn’t to do more.
The goal is to do the right things consistently.
What Actually Works After 40
Prioritise Strength Training
Strength training should be the foundation of your programme.
Benefits include:
• increased muscle mass
• improved metabolism
• improved insulin sensitivity
• stronger bones and joints
• better posture
Most men can achieve excellent results training just:
2–4 times per week
when the programme is properly structured.
Focus on Progressive Overload
Muscles grow when they are challenged progressively.
This means gradually improving:
• weights lifted
• repetitions performed
• movement quality
• training volume
Random workouts rarely produce significant muscle growth.
Structured progression does.
Increase Protein Intake
One of the most common issues we see is inadequate protein consumption.
Protein helps:
• build muscle
• preserve lean tissue
• improve recovery
• control hunger
Many men over 40 benefit from increasing protein intake significantly compared to what they’re currently eating.
Prioritise Sleep
Sleep is one of the most powerful muscle-building tools available.
Poor sleep impacts:
• recovery
• testosterone production
• training performance
• hunger regulation
Most adults should aim for:
7–9 hours of quality sleep per night.
Manage Stress Better
Muscle growth requires recovery.
Recovery requires managing stress.
Simple strategies include:
• daily walks
• regular training
• better boundaries around work
• reducing unnecessary commitments
• improving sleep routines
What About Testosterone?
Many men automatically blame testosterone.
While testosterone does gradually decline with age, lifestyle often plays a bigger role than people realise.
Poor:
• sleep
• body composition
• stress management
• activity levels
can significantly impact hormonal health.
Improving these areas often leads to dramatic improvements in:
• energy
• performance
• recovery
• body composition
