Staying active and making healthy choices is important, especially as we get older. Strength training and maintaining a healthy body composition can make a big difference in how we move, look, and feel as we age.
Understanding Body Composition
Body composition is the balance of muscle, fat, bone, and other tissues in your body. As we get older, this balance tends to shift. Without regular exercise, body fat usually increases, and muscle mass can start to decrease. This change can impact your health and increase disease risks.
Muscle loss, known as sarcopenia, often starts in your 40s and speeds up with age. At the same time, fat storage—especially around the belly—can increase, even if your weight stays the same. This shift in body composition can slow your metabolism, making it easier to gain fat. Hormonal changes, such as lower testosterone and estrogen levels, also contribute to these changes.
Why Strength Training Matters
Strength training, or resistance training, involves exercises that use weights, resistance bands, or body weight to strengthen muscles. It’s one of the best ways to combat age-related body changes. Here are some key benefits of strength training as you age:
- Maintains and Builds Muscle: Strength training can help you prevent muscle loss and even build new muscle.
- Increases Metabolism: Muscle burns more calories than fat, even at rest, so by building muscle, you’re boosting your calorie burn all day.
- Helps Burn Fat: Strength training not only builds muscle but also helps burn fat by raising your metabolism.
- Strengthens Bones: Lifting weights improves bone density, which reduces the risk of osteoporosis.
- Improves Balance and Flexibility: Strong muscles around your joints help you stay steady and can reduce the risk of falls.
- Lowers Chronic Disease Risks: Strength training can decrease the risk of diabetes, heart disease, and arthritis.
Adjusting Your Strength Training Routine by Age
As you age, your strength training goals may change. Here’s a general guide for each stage:
- 40s: Focus on maintaining muscle and preventing early muscle loss. Include exercises like squats, lunges, and deadlifts to build strength. If you’re new to strength training, start slowly and increase intensity gradually.
- 50s and 60s: Prioritize functional strength and flexibility. Exercises that improve balance, such as planks and resistance band work, are especially helpful. Make time for recovery and add stretching or yoga for flexibility.
- 70s and Beyond: In your 70s and beyond, it’s all about maintaining independence and supporting everyday movements. Light weights, resistance bands, and bodyweight exercises are ideal. Listen to your body, and make adjustments to stay safe and comfortable.
Additional Tips to Support Muscle Mass
- Eat Enough Protein: Protein helps your muscles repair and grow, especially after workouts. Foods like lean meat, fish, beans, and eggs are excellent sources.
- Stay Hydrated: Hydration keeps your muscles working well, so be sure to drink enough water daily.
How to Start a Strength Training Routine
If you’re new to strength training, start with bodyweight exercises, light weights, or resistance bands. As you gain confidence, you can increase the weight or number of reps. Set realistic goals and track your progress to stay motivated. Consistency is key—strength training provides benefits that build over time.

Strength training is one of the best ways to improve body composition and support your health as you age. It’s never too late to start, and by making it a regular part of your routine, you can set yourself up for a stronger, healthier future.


One of the best things you can do when it comes to tracking your progress with fitness is a fitness assessment. A fitness assessment is roughly a 30–60-minute consultation with a health and fitness professional where you are tested on the 5 components of fitness: body composition, muscular strength, muscular endurance, flexibility, and cardiovascular endurance. Some assessments may also test for balance, mobility, or more sports performance biased like power and agility. But for the sake of this article, we are focusing on the 5 components of fitness.
While practicing social distancing remains a priority for everyone, finding ways to stay physically active should also remain a priority. This is particularly true for older adults who may find themselves feeling increasingly isolated and vulnerable to remain safe. Exercise has long proven to provide numerous health benefits both for your physical well-being as well as your emotional well-being including:
For years, fitness professionals have been trained to use Body Mass Index (BMI) as a prescreening tool when individuals join a fitness program. It was part of the recommendations by the 
Body Mass Index (BMI) vs. Body Composition: These measurements are used in the healthcare and corporate fitness worlds to help identify risk for heart disease, diabetes, stroke, and cancer. But which is best? Many experts reason that both tools can be useful in different circumstances.
