Building Strength After Your 40s
The Benefits of Strength Training
This is Granny Guns. At the ripe age of 58 years young she had a whole host of eating disorders and health problems. After a surgery that year she decided it was time for change. It was then she took up fitness and became a body builder that would go viral around the world as an inspiration to all.
How did she do it? And can you do it to?
The answer is yes. As people grow old the fall into the habit of only doing things that are cardio based and leave behind strength training. However this is were they make mistakes. Keep on Reading to see the benefits of strength training and how you can get back into the swing of things and improve your life.
The Benefits of Strength Training for People Over 40
As we grow older, the importance of maintaining an active lifestyle becomes increasingly clear. Yet, many people over 40 still focus primarily on cardiovascular exercises, such as jogging or cycling, while overlooking strength training. This imbalance can be a missed opportunity, as research has demonstrated that strength training offers a wealth of benefits, particularly for people over 40. In this newsletter, we’ll explore why strength training is so essential as we age, how it benefits both the body and mind, and provide actionable steps to incorporate it into your fitness routine.
Why Strength Training Matters After 40
As we age, our bodies naturally undergo a series of changes that can affect our strength, balance, and overall health. Muscle mass begins to decline after the age of 30 in a process called sarcopenia, with studies estimating that adults lose between 3-8% of their muscle mass per decade thereafter. Without intervention, this decline can lead to reduced mobility, increased body fat, and a higher risk of injury.
Strength training, or resistance training, offers an effective solution to counteract these age-related changes. Regular strength workouts help slow down, or even reverse, muscle loss, while simultaneously strengthening bones, improving balance, and enhancing metabolic health. These benefits are especially important for those over 40, who may be at greater risk for conditions such as osteoporosis, arthritis, and metabolic diseases like type 2 diabetes.
Building and Maintaining Muscle Mass
One of the most well-known benefits of strength training is its ability to build and maintain muscle mass. After the age of 40, people experience a steady decline in muscle fibers, particularly in the fast-twitch fibers, which are responsible for strength and power. When muscles are not used or challenged, they atrophy over time. Strength training stimulates muscle growth by challenging the muscles to adapt and grow stronger with each workout.
More than just aesthetics, maintaining muscle mass has functional benefits. Everyday tasks such as carrying groceries, climbing stairs, and even maintaining good posture are made easier when your muscles are strong. Additionally, strength training can reduce the risk of falls by improving balance and coordination—critical concerns as we age.
Boosting Bone Density
Bone health is another area where strength training shines. As we age, bone density tends to decrease, especially in postmenopausal women, making us more susceptible to fractures and conditions like osteoporosis. Research has shown that strength training not only slows bone loss but can actually increase bone density by exerting pressure on the skeletal system.
Exercises such as weightlifting, squats, and lunges create mechanical stress on the bones, prompting them to become denser and stronger in response. This process, called bone remodeling, is vital for maintaining bone health in older adults. Regular strength training can help stave off the risk of fractures, which often have more severe consequences for older individuals in terms of mobility and quality of life.
Improved Metabolic Health and Fat Loss
Strength training also plays a critical role in boosting metabolism and promoting fat loss. As muscle mass increases, so does the body’s basal metabolic rate (BMR), which refers to the number of calories burned at rest. Since muscle tissue is more metabolically active than fat tissue, the more muscle you have, the more calories your body burns throughout the day—even when you’re not exercising.
Incorporating strength training into your routine can lead to improved insulin sensitivity, helping to regulate blood sugar levels and reduce the risk of metabolic disorders like type 2 diabetes. This is especially important for people over 40, as insulin resistance tends to increase with age.
Enhancing Mental Health and Cognitive Function
Beyond the physical advantages, strength training offers a host of mental health benefits. Engaging in regular resistance exercise has been linked to reduced symptoms of depression and anxiety, improvements in mood, and better overall mental well-being. The psychological benefits of strength training are due in part to the endorphin release that accompanies physical activity, but there’s more to the story.
Strength training can enhance cognitive function by improving memory, attention, and executive functioning, which are particularly vulnerable to decline as we age. Studies have shown that older adults who engage in regular strength training exhibit better cognitive performance and are at a lower risk for developing dementia.
Reducing the Risk of Chronic Diseases
Strength training is also highly effective in reducing the risk of several chronic diseases, many of which become more common after the age of 40. For example, resistance exercise has been shown to lower blood pressure and improve cardiovascular health. By increasing muscle mass and reducing fat, strength training also helps reduce chronic inflammation, which is a contributing factor to conditions such as heart disease, diabetes, and some forms of cancer.
Strength Training vs. Cardio: The Ideal Balance
While cardiovascular exercise is excellent for heart health, the mistake many people over 40 make is focusing solely on cardio at the expense of strength training. While cardio workouts burn calories and improve cardiovascular fitness, they do not address the muscle and bone loss that comes with aging.
The ideal approach is to strike a balance between strength training and cardiovascular exercise. For optimal health, the American Heart Association recommends at least 150 minutes of moderate aerobic activity each week, along with two or more days of strength training targeting all major muscle groups.

Getting Started with Strength Training
If you’re new to strength training or haven’t done it in a while, the prospect of lifting weights might feel daunting. However, it’s important to remember that strength training doesn’t require heavy barbells or complicated machines. In fact, many exercises can be performed with body weight alone or with minimal equipment like resistance bands or dumbbells.
Here are a few beginner-friendly tips to help you get started:
1. Consult with a Professional: If possible, consult with a personal trainer or physical therapist to ensure you’re performing exercises correctly and safely. This is especially important if you have any pre-existing health conditions or concerns about injuries.
2. Start Slowly: Begin with lighter weights or resistance bands and gradually increase the intensity as your strength improves. Aim for 8-12 repetitions of each exercise, with 2-3 sets per muscle group.
3. Focus on Form: Proper form is critical for avoiding injury and ensuring that you’re working the intended muscles. Avoid rushing through exercises and prioritize quality over quantity.
4. Incorporate Variety: Mix up your routine with a combination of exercises that target all the major muscle groups, including the legs, chest, back, shoulders, and arms. Exercises like squats, lunges, push-ups, and rows are great for building overall strength.
5. Progress Gradually: As you become more comfortable with strength training, gradually increase the weight or resistance to continue challenging your muscles. Progressive overload is key to muscle growth.
Conclusion: Embrace Strength Training for Longevity
The benefits of strength training for people over 40 extend far beyond aesthetics. It’s about preserving and enhancing your functional capacity, maintaining independence, and improving quality of life. Whether you’re looking to build muscle, strengthen your bones, or improve your mental health, incorporating strength training into your routine is one of the best decisions you can make for your long-term health.
