Energy and Fatigue Archive

A side lunge with a knee lift works the inner and outer thigh muscles and helps improve balance.

A strong core serves as the foundation for upper- and lower-body movements. It helps maintain a healthy posture and prevents back injuries and falls. Like all muscles, the core muscles weaken as people age, so it's important for people to do core exercises on a regular basis. The best core exercises are movements that activate as many of the core muscles as possible at one time. Some examples include planks, diagonal chops, and deadbugs.

Losing 5% of one's total body weight can result in clinically significant physiologic changes. For example, losing a little weight can reduce heartburn, knee pain, blood pressure, and diabetes risk. Losing 5% of one's body weight may also lead to better sexual function, more restorative sleep, extra energy, and more self-esteem. To reach a 5% reduction in total body weight, it helps to exercise; eat a healthy diet rich in lean proteins, whole grains, fruits, vegetables, legumes, nuts, and seeds; and get enough sleep.

Fitness trackers accurately record objective data about physical activity, including the pace, distance, intensity, and duration of exercise. Knowing that something is keeping track of every move can motivate people to stick with a workout.

According to a 2023 observational study, greater cardiorespiratory fitness in men was linked to a lower risk of death from colon, lung, or prostate cancer.

Running and walking are two of the best exercises — and among the easiest to adopt — for almost everyone. But it can be easy to get in stuck in a rut. Some ways to reignite the excitement and boost commitment for these activities are to set goals and challenges, enlist a workout buddy, explore new routes, do more interval training, and buy fun accessories.

As men age, their metabolism naturally slows, and they burn calories more slowly. They can be less active and consume extra calories. The result is a buildup of visceral fat inside the abdominal cavity and around vital organs. This can raise heart disease risk factors, such as blood pressure, blood sugar, and total cholesterol levels. The best way to fight visceral fat is with aerobic exercise, strength training, and a healthy diet that includes plenty of protein.

Fitness levels rapidly diminish when people abruptly stop workouts. Cardiovascular fitness declines within weeks, while muscle strength deteriorates after about two months. The longer a person hasn't exercised, the longer it will take to regain prior fitness levels. To restart exercise, people should seek their doctor's approval, especially if they have chronic conditions; build up exercise levels slowly; do the same types of exercises they once enjoyed; find an exercise partner; and track progress with wearable devices or by keeping a paper log.

Fatigue is a relative term, meaning each of us evaluate our current energy level based upon how we feel most of the time. For example, people who are very energetic and go nonstop from early morning to late at night might say they have fatigue if they felt like most of us do every day.

Despite that variation, most people do have a sense when their level of fatigue feels like something more than just being tired. If that's case, even if it lasted only seven to 10 days, it's time to call your doctor's office. Signs that your fatigue might be related to an underlying illness or infection include low grade fever, night sweats, shortness of breath or loss of appetite. Other triggers for calling your doctor might be waking up exhausted despite a good night's sleep, not feeling motivated to begin the day, or struggling to do activities that are usually easy for you.
