Today, I’d like to explore one of the most powerful tools God has given us to protect our health, improve our quality of life, and increase our ability to serve others: exercise.
Many people think of exercise primarily as a way to lose weight, but its benefits extend far beyond appearance. Regular physical activity affects nearly every organ system in the body. It improves heart health, brain function, mood, sleep, strength, immune function, and longevity. Research continues to show that exercise is one of the most effective interventions available for preventing chronic disease and maintaining health throughout life.
The Bible reminds us in 1 Corinthians 6:19-20 that our bodies are temples of the Holy Spirit and that we should honor God with our bodies. Exercise can be viewed as one practical way to steward the physical gifts God has entrusted to us. Here are twelve benefits of exercise for your health.
- Exercise Improves Heart Health
Heart disease remains one of the leading causes of death worldwide. One of the most remarkable benefits of exercise is its ability to strengthen the heart and blood vessels. Regular physical activity lowers blood pressure, improves cholesterol levels, enhances circulation, and reduces the risk of heart attack and stroke
Research from the CDC shows that adults who engage in at least 150 minutes of moderate physical activity per week significantly lower their risk of cardiovascular disease. Even small increases in activity can provide meaningful benefits. Recent research suggests that increasing weekly activity beyond minimum recommendations may further reduce cardiovascular risk by as much as 30%.
Think of exercise as training your heart to become stronger and more efficient. Just as a muscle becomes stronger with use, so does the cardiovascular system.
- Exercise Helps You Live Longer
One of the most compelling findings in modern health research is the relationship between physical activity and longevity. The CDC estimates that many premature deaths could be prevented if adults increased their physical activity levels. Even adding as little as 10 minutes of moderate-to-vigorous activity per day can make a measurable difference.
Taking more steps a day also helps lower the risk of premature death from all causes. In one study, for adults younger than 60, the risk of premature death leveled off at about 8,000 to 10,000 steps per day. For adults 60 and older, the risk of premature death leveled off at about 6,000 to 8,000 steps per day.
Research has also shown that regular walking can significantly reduce the risk of heart disease and early death. Even 10- to 15-minute walks provide measurable benefits. The encouraging message is that you do not have to become a marathon runner. Consistent movement is what matters.
- Exercise Protects Brain Health
Many people are surprised to learn that exercise benefits the brain almost immediately. After a single session of moderate exercise, people often experience improved concentration, better mood, reduced anxiety, and enhanced mental clarity. Long-term physical activity is associated with lower risks of cognitive decline, dementia, and depression.
Scientists believe exercise increases blood flow to the brain and stimulates the release of growth factors that support healthy brain cells. For students, professionals, and older adults alike, exercise can be thought of as a natural brain booster.
- Exercise Helps Control Weight
Weight management is one of the most visible benefits of exercise. When we move, we burn calories and improve our body’s ability to regulate blood sugar and metabolism.
However, exercise does more than simply burn calories. It helps preserve muscle mass, which keeps metabolism functioning more efficiently as we age. Combined with healthy eating habits, regular exercise is one of the most effective long-term strategies for maintaining a healthy weight. Rather than viewing exercise as punishment for eating, we can view it as a celebration of what our bodies are capable of doing.
- Exercise Reduces the Risk of Diabetes
Type 2 diabetes affects millions of people worldwide. Exercise helps muscles use glucose more effectively and improves insulin sensitivity. As a result, the body requires less insulin to regulate blood sugar levels.
Research consistently shows that regular physical activity lowers the risk of developing type 2 diabetes and can help people who already have diabetes better manage their condition. This benefit can begin with something as simple as regular walking.
- Exercise May Lower Cancer Risk
One of the most exciting areas of research involves exercise and cancer prevention. The CDC reports that regular physical activity is associated with a lower risk of at least eight types of cancer, including colon cancer, breast cancer, endometrial cancer, kidney cancer, and lung cancer.
Exercise also improves the quality of life and physical functioning among many cancer survivors. A meta analysis in Australia revealed that “exercise is one of the best things a cancer patient can do.” The study also said, ” If exercise were a pill, it should be given to every cancer patient worldwide.”
An MD Anderson study with mice showed that the mice with moderate exercise routines survived chemotherapy and responded better to immunotherapy.
Researchers believe exercise helps regulate hormones, reduces inflammation, improves immune function, and maintains a healthy body weight—all factors linked to cancer risk.
- Exercise Strengthens Bones and Muscles
As we age, we naturally lose muscle mass and bone density. Strength training and weight-bearing activities help maintain muscle strength, improve balance, protect bone density, and reduce the risk of fractures.
The World Health Organization and CDC both emphasize the importance of including muscle-strengthening activities in addition to aerobic exercise. Maintaining strength is not just about appearance. It affects independence, mobility, and quality of life.
- Exercise Improves Sleep
Many people struggle with sleep. Research shows that regular physical activity improves sleep quality and can help people fall asleep more easily.
When we exercise, our bodies develop healthier sleep-wake cycles. Better sleep then supports memory, immune function, emotional health, and physical recovery. This creates a positive cycle in which exercise improves sleep and good sleep improves exercise performance.
- Exercise Supports Mental and Emotional Health
Stress, anxiety, and depression have become increasingly common. Exercise acts as a natural stress reliever by stimulating the release of endorphins and other beneficial brain chemicals. Studies consistently show that physically active individuals experience lower anxiety levels, reduced symptoms of depression, and improved overall well-being.
I used exercise throughout the cancer journey to help me deal with anxiety, depression, and worry. In a world filled with stress and uncertainty, exercise can be a valuable tool for maintaining emotional resilience.
- Exercise Mobilizes Stem Cells
As I discussed in another video called, “Nine Proven Ways to Increase Stem Cell Activity,” among all lifestyle factors, exercise has some of the strongest evidence for mobilizing stem cells.
The benefits of exercise include improving tissue repair, supporting immune function, enhancing blood vessel growth, and promoting healthy aging. These benefits can be obtained by brisk walking, swimming, cycling, and strength training. During my cancer journey and treatments, I walked two miles twice each day–even during chemotherapy! I now see that this daily exercise regimen implemented by me to lessen stress and anxiety gave me many more benefits than I anticipated.
It’s best to aim for 150 minutes of moderate exercise weekly, and strength training 2-3 times per week. Any why? Because vigorous exercise mobilizes stem cells.
- Exercise Boosts Mitochondrial Health
There’s no better way to boost your mitochondria than to move your body. According to Robb Wolfe, a biochemistry researcher and lifestyle expert, “High-intensity exercise response upregulates recovery mechanisms within the mitochondria and our DNA.” Exercise corrals our cells towards health rather than dysfunction, and when your mitochondria are healthy, you are healthy.
Neurologist and medical researcher Dr. Datis Kharrazian adds to this the importance of mitochondrial biogenesis, a process within the cell in which new mitochondria are self-replication. According to Dr. Kharrazian, “The more active you are, the more mitochondria you make, and those cells function longer.” After chemotherapy and radiation, I can’t think of a better way to assist your mitochondria than to exercise on a regular basis.
Dr. Robert Elliott, the oncologist, surgeon, and medical researcher who wrote commentary in my book said, “A regular exercise regimen is important for maintaining mitochondrial health and improving cellular respiration. Movement upgrades the expression of PGC-1alpha, which stimulates mitochondrial biogenesis and intracellular antioxidants.” There’s no better and inexpensive way to boost your mitochondria than exercise.
- Exercise Helps Your Lymphatic System to Take out the Trash
Exercise enhances every stem and organ in the body, but your lymphatic system, which is part of your immune system, only works when you exercise. It is the only system in our body that requires exercise to take out the trash in our body. Before and after each surgery, I walked in the cancer journey. I also walked 2 miles before and after chemotherapy and every day in between. Although I did this exercise to relieve the stress and anxiety that a cancer journey can bring, I did not realize until years later, the benefits to my mitochondria or to my lymphatic system. As the chemo was damaging this battery pack in my cells and filling my body with poisons, my exercise was stimulating those same battery packs in my cells and also pumping those chemicals out of my body.
Every Movement Counts
One of the biggest misconceptions about exercise is that it must occur in a gym. Physical activity includes walking, gardening, dancing, swimming, cycling, housework, playing with grandchildren, and working in the yard.
The World Health Organization emphasizes that all movement contributes to better health. For some people, a daily walk may be the perfect starting point. For others, strength training, cycling, or swimming may be more enjoyable. The best exercise is often the one you enjoy enough to continue doing.
Current guidelines generally recommend at least 150 minutes of moderate-intensity activity per week, or 75 minutes of vigorous activity per week. Muscle-strengthening activities should be done at least two days per week.
Conclusion
Exercise is one of the closest things we have to a miracle medicine. It strengthens the heart, protects the brain, lowers the risk of chronic disease, supports emotional health, improves sleep, helps maintain independence, and may even extend life.
As we care for our bodies, we honor the gift of life that God has given us. Small steps taken consistently can lead to remarkable improvements in health and well-being.
