Achieving a muscular and defined torso becomes increasingly challenging as men age, particularly after the age of 40. Hormonal changes, slower metabolism, and age-related muscle loss (sarcopenia) can all hinder your progress. However, with the right strategies, it’s possible to build an impressive physique even as the years go by.
This article outlines five scientifically-backed hacks that can help men over 40 get jacked and muscular. Each hack is grounded in research and designed to maximise your gains without risking injury.
Hack 1: Prioritise Compound Movements for Maximum Muscle Stimulation

The Science Behind Compound Movements
Compound movements, such as squats, deadlifts, bench presses, and rows, involve multiple joints and muscle groups. These exercises are essential for building muscle mass and strength, particularly as you age. Research has shown that compound exercises stimulate a greater release of anabolic hormones like testosterone and growth hormone compared to isolation exercises . These hormones are crucial for muscle growth and fat loss, which are key to achieving a jacked torso.
Why Compound Movements Work Better After 40
As you age, your body’s ability to recover from workouts diminishes, making it crucial to focus on exercises that offer the most benefit for your time and energy. Compound movements not only allow you to lift heavier weights, which is vital for muscle hypertrophy, but they also engage more muscle fibres, leading to greater overall muscle growth . Furthermore, they help improve functional strength, which is increasingly important as we age.
Implementing Compound Movements in Your Routine
To maximise muscle growth and strength, aim to base your workouts around the following compound exercises:
- Squats: Targeting the quads, glutes, hamstrings, and core.
- Deadlifts: Engaging the posterior chain, including the hamstrings, glutes, and lower back.
- Bench Press: Focusing on the chest, shoulders, and triceps.
- Pull-Ups/Rows: Working the back, biceps, and forearms.
Perform these exercises 2–3 times per week, ensuring adequate rest between sessions to allow for recovery.
Hack 2: Optimise Your Diet for Muscle Growth
Understanding the Nutritional Needs of Men Over 40
Diet plays a crucial role in muscle development, particularly as you age. After 40, your metabolism slows down, and your body’s ability to synthesise protein decreases, making it harder to build and maintain muscle mass . Therefore, it’s essential to adjust your diet to meet your body’s changing needs.
Protein Intake: The Building Block of Muscle
Protein is the most critical macronutrient for muscle growth. Studies have shown that older adults require higher protein intake to stimulate muscle protein synthesis effectively. A study published in the American Journal of Clinical Nutrition suggests that men over 40 should consume at least 1.6 grams of protein per kilogram of body weight daily to maximise muscle gain.
Macronutrient Balance and Timing
In addition to protein, it’s vital to maintain a balanced intake of carbohydrates and fats. Carbohydrates provide the energy needed for intense workouts, while fats are essential for hormone production, including testosterone. Research indicates that consuming a mix of protein and carbohydrates post-workout can significantly enhance muscle recovery and growth.
Supplementation: Supporting Muscle Growth
While a balanced diet should be your primary focus, certain supplements can help support muscle growth, especially for men over 40. Creatine, for example, has been shown to improve muscle strength and size in older adults. Additionally, omega-3 fatty acids can reduce muscle soreness and improve recovery time.
Hack 3: Focus on Recovery to Combat Age-Related Muscle Loss

The Importance of Recovery After 40
Recovery becomes increasingly important as you age due to the natural decline in muscle repair and regeneration processes. Overtraining can lead to muscle breakdown, fatigue, and injuries, which are more challenging to recover from after 40 .
Sleep: The Foundation of Recovery
Quality sleep is paramount for muscle recovery and growth. During sleep, your body releases growth hormone, which plays a crucial role in repairing muscle tissues. A study published in the Journal of the American Geriatrics Society found that poor sleep is linked to decreased muscle mass and strength in older adults . Aim for 7–9 hours of sleep per night to optimise recovery.
Active Recovery and Mobility Work
Incorporating active recovery and mobility work into your routine can also aid in muscle recovery and prevent injuries. Activities such as walking, swimming, or cycling at a low intensity help increase blood flow to muscles, promoting faster recovery . Additionally, regular stretching and mobility exercises can improve joint health and flexibility, which are critical as you age .
Hack 4: Leverage the Power of Progressive Overload
What is Progressive Overload?
Progressive overload is the gradual increase of stress placed on the body during exercise. This principle is essential for continued muscle growth and strength gains, particularly as your body adapts to your workout routine .
Why Progressive Overload is Crucial After 40
As you age, your muscles naturally become more resistant to growth. Therefore, continually challenging your muscles by increasing the weight, reps, or intensity of your exercises is vital. This not only promotes muscle hypertrophy but also enhances neuromuscular adaptations, leading to greater strength .
Implementing Progressive Overload Safely
To safely implement progressive overload, increase the weight you lift by 2–5% every 1–2 weeks, depending on your progress and recovery. Alternatively, you can increase the number of repetitions or sets you perform. Ensure you maintain proper form to avoid injuries, and consider cycling between periods of higher intensity and lower intensity to allow for adequate recovery.
Hack 5: Manage Stress and Cortisol Levels

The Impact of Cortisol on Muscle Growth
Cortisol, often referred to as the “stress hormone,” can have a significant impact on muscle growth. High levels of cortisol, which can be triggered by chronic stress, lead to muscle breakdown and inhibit muscle protein synthesis . Managing stress is therefore crucial for maintaining a muscular physique, especially after 40.
Stress Management Techniques
To keep cortisol levels in check, it’s important to incorporate stress management techniques into your daily routine. Practices such as meditation, deep breathing exercises, and yoga have been shown to reduce cortisol levels and improve overall well-being .
The Role of Nutrition in Managing Cortisol
Diet also plays a role in managing cortisol levels. Consuming foods rich in antioxidants, such as fruits and vegetables, can help mitigate the oxidative stress that contributes to elevated cortisol. Additionally, ensuring adequate intake of magnesium, which has been shown to reduce cortisol, can be beneficial .
Conclusion
Building a jacked and muscular torso after 40 is entirely achievable with the right approach. By prioritising compound movements, optimising your diet, focusing on recovery, leveraging progressive overload, and managing stress, you can make significant gains. Each of these hacks is grounded in scientific research and designed to work with the physiological changes that come with age. Implement these strategies consistently, and you’ll be well on your way to achieving the muscular physique you desire.
