What You'll Learn
Eat protein-rich foods
Eating protein-rich foods is essential for building and maintaining muscle strength. Protein provides the body with amino acids, which are the building blocks of muscle. Aim to include a variety of protein sources in your diet, such as lean meats, poultry, fish, dairy, eggs, and plant-based sources like beans and legumes.
Meats, such as chicken, turkey, and red meat, are excellent sources of complete proteins, meaning they provide all the essential amino acids needed for muscle building. Fish is also an excellent choice, offering not only high-quality protein but also healthy omega-3 fatty acids, which have anti-inflammatory properties. Omega-3s can help improve muscle protein synthesis and reduce inflammation that contributes to muscle breakdown.
Dairy products like yogurt are another good source of protein and contain additional nutrients beneficial for muscle health, such as calcium. Calcium is essential for maintaining bone health, and strong bones are crucial for performing exercises that promote muscle strength. Eggs are also a highly recommended protein source, as they provide essential amino acids and offer a complete package of nutrients, including healthy fats and vitamins, that support overall health and muscle function.
In addition to animal-based sources, plant-based proteins like beans and legumes are excellent alternatives. These foods are rich in protein and offer a host of other nutrients, including fibre, vitamins, and minerals. They are particularly beneficial for those following a vegetarian or vegan diet or looking to reduce their meat intake.
By incorporating a variety of protein-rich foods into your diet, you provide your body with the essential amino acids needed to build and repair muscle tissue. This, combined with regular strength training and overall physical activity, forms a solid foundation for maintaining strong and healthy muscles throughout your life.

Do resistance training
Resistance training is a form of exercise that increases muscular strength and endurance. It is based on the principle that muscles will work to overcome a resistance force when required to do so. When done repeatedly and consistently, your muscles will become stronger.
Resistance training can be done using weights, bands, or even your own body weight working against gravity. It can be easily incorporated into your daily routine, such as during commercial breaks while watching television. The key is to work out consistently and vary your workouts to challenge a wider range of muscles. For example, you can increase the number of repetitions, the duration of your workout, or the frequency of your workouts, keeping in mind that each muscle group needs at least 48 hours of recovery time.
The benefits of resistance training include improved muscle strength and tone, which can help protect your joints from injury. It can also help maintain flexibility and balance, which is important for remaining independent as you age. Additionally, resistance training can aid in weight management and increasing your muscle-to-fat ratio, as muscle gains increase your resting metabolic rate, causing your body to burn more calories at rest.
Resistance training can be particularly useful in slowing the effects of sarcopenia, the natural loss of muscle mass, quality, and strength that comes with ageing. By engaging in regular resistance training, older adults can improve their quality of life and increase their life expectancy.

Manage health conditions
As we age, our bodies go through several changes, and muscle loss is one of the most noticeable ones. This loss of muscle strength can make it harder to perform daily activities and may also have significant health consequences. Managing health conditions and making appropriate lifestyle changes can help in building and retaining muscle strength.
- Exercise: Regular exercise is crucial for maintaining muscle strength. Aim for strengthening exercises at least 2 to 3 times a week. Weight training, resistance exercises, and aerobic exercise are particularly beneficial for maintaining muscle mass and improving cardiovascular health. Walking is an excellent low-impact option to increase mobility and enhance blood flow.
- Nutrition: Consuming a balanced diet with sufficient protein is essential for muscle health. The body uses amino acids from protein-rich foods like chicken, turkey, fish, eggs, yogurt, and beans to build muscle. Additionally, increasing your intake of omega-3 fatty acids, found in salmon, walnuts, and flaxseeds, can help reduce inflammation and improve muscle protein synthesis.
- Medical Conditions: Keeping chronic diseases like diabetes under control is vital for maintaining muscle strength. Managing conditions like diabetes, which can impact blood flow and nutrient delivery to muscles, is essential. Additionally, maintaining a healthy body weight is crucial, as obesity can contribute to reduced muscle mass and increase the risk of associated health complications.
- Vitamins and Supplements: Ensuring adequate vitamin D intake is important for muscle health. Vitamin D aids in muscle protein synthesis, and while it can be obtained through sun exposure, older adults may require longer exposure times or consider taking supplements after consulting a physician.
- Hydration: Staying properly hydrated is crucial for muscle health. Dehydration can impact muscle contraction and endurance. Drinking enough water helps deliver nutrients to the muscles and remove waste products.
- Smoking and Alcohol: Smoking and excessive alcohol consumption can negatively impact muscle health. Smoking reduces blood and oxygen flow to the muscles, impairing their function. Alcohol can interfere with the muscle repair and growth process.
By managing these health conditions and incorporating recommended lifestyle changes, you can effectively maintain and improve your muscle strength as you age.

Stay hydrated
Staying hydrated is essential for keeping muscles strong and maintaining overall health. Dehydration can affect how your muscles contract and lower your endurance. It can also impact your brain, impairing your motor control, decision-making abilities, and concentration.
To ensure you are adequately hydrated, it is important to consume enough fluids, especially water. The American Council on Exercise suggests drinking 17 to 20 ounces of water a few hours before exercising, followed by 8 ounces of water 20 to 30 minutes before you begin or during your warm-up. During exercise, aim for 4 to 8 ounces of fluid every 15 to 20 minutes, adjusting based on the intensity of the activity and the climate. For moderate activity in a cool climate, you may need only 4 ounces every 20 minutes, while high-intensity exercise in a hot climate may require 8 ounces every 15 minutes.
It is important to note that thirst is not a reliable indicator of hydration status. By the time you feel thirsty, you are likely already dehydrated. Instead, monitor the color of your urine, which should be pale and clear when you are well-hydrated. Dark-colored urine indicates dehydration. Additionally, a lack of sweating during vigorous activity can be a sign of dehydration and heat exhaustion.
While water is the most basic and cost-effective form of hydration, other options include sports drinks, caffeinated beverages, and even chocolate milk. Sports drinks can help with hydration and replenishment during exercise, but it is important to be mindful of their sugar content. If you choose a caffeinated beverage, be aware that caffeine has diuretic effects, although the fluid content usually offsets any dehydrating impact.
To maintain hydration, you can also eat certain foods. Fruits like pineapple and watermelon are excellent sources of hydration, and you can also infuse your water with electrolytes and water-soluble vitamins.

Avoid smoking
Smoking has been shown to have a detrimental effect on muscle strength. The habit impairs the delivery of oxygen to the mitochondria, leading to impaired generation of adenosine triphosphate and hampered contractile function. Smoking also impairs muscle protein synthesis and increases the expression of genes associated with impaired muscle maintenance.
Research has shown that cigarette smoke directly damages muscles in the body. A study published in The Journal of Physiology indicates that smoking decreases the number of small blood vessels that bring oxygen and nutrients to the muscles in the legs. This can impact metabolism and activity levels, both of which are risk factors for many chronic diseases, including COPD and diabetes.
Another study of healthy, young (18- to 45-year-old) smokers versus non-smokers found that smokers had higher levels of oxidative stress and skeletal muscle dysfunction in their dominant leg. This is due to the increased level of carbon monoxide in the body, which interferes with respiratory and muscle proteins, including hemoglobin, myoglobin, and other proteins.
Smoking also increases muscle fatiguability, meaning smokers' muscles tend to get tired quicker compared to non-smokers. This is due to reduced blood flow to the muscles, reduced oxygen binding to hemoglobin, and reduced adenosine triphosphate production by muscle mitochondria.
To keep muscles strong, it is important to avoid smoking. The harmful effects of smoking on muscle strength and function can be reduced by cutting down on the number of cigarettes smoked per day, with measurable benefits seen at less than 20 cigarettes per day, and preferably less than 10.
