Performing regular biceps curls can build stronger biceps muscles and help older men with lifting, carrying, and holding heavy objects.

Some supplements can interfere with lab tests to diagnose or monitor health conditions, which can lead to life-threatening misdiagnoses or unnecessary additional testing. Biotin (vitamin B₇) can skew results from a blood test to diagnose heart attack. Other problematic supplements include vitamin C, which can interfere with blood sugar readings and stool tests; calcium, which can make bones appear denser than they are on bone density scans; and creatine, which can lead to falsely high readings of creatinine, a marker for kidney disease.

Yoga has modest yet positive effects on several factors linked to cardiovascular health, including lower blood pressure and lower levels of harmful LDL cholesterol. The postures, breathing, and meditation practices inherent in yoga help cultivate the relaxation response, which trains the body to be less reactive during times of stress. People new to yoga should seek out a beginner, gentle, or chair yoga class, especially those who are over 65 or who have any medical conditions.

An estimated 2.5 million Americans have implanted heart devices, which can be affected by magnetic or electrical interference from electric vehicle charging stations, induction cooktop stoves, and smaller gadgets such as smartphones and wireless earbuds. Magnetic energy can cause pacemakers to revert to a preset mode that may be faster or slower than the programmed heart rate. Electrical interference can cause a pacemaker or implanted cardioverter defibrillator to mistakenly stop functioning or deliver an unneeded shock.

Daily brisk walking is great for health, and adding a few simple moves or tools can make it even better. To boost balance, it helps to occasionally walk heel-to-toe during the walk or turn sideways and take 10 side steps. To promote healthy bones and muscles, it helps to wear a weighted vest on a walk. To boost heart health, it helps to add arm raises during the walk or periodically jog for 30 seconds to a minute.

A variety of coaches can help people reach their particular health goals. Health and wellness coaches inspire and guide clients to shift their mindset and develop new, healthy behaviors. Fitness professionals—such as personal trainers or exercise physiologists—develop and prescribe exercise regimens to help clients. Dietitians develop eating plans tailored to clients’ needs, such as weight loss or gain, or preventing or treating chronic disease. And culinary coaches use coaching principles and cooking expertise to teach people how to shop for and prepare healthy meals.

Age-related muscle loss is a natural part of getting older. But muscle loss can occur faster after an injury, illness, or any prolonged period of inactivity, leading to muscle atrophy. The consequences can mean overall weakness, poor balance, and even frailty. The good news is that it's possible to rebuild lost muscle through a comprehensive program that includes physical therapy, strength training, cardio, flexibility, and a nutrition plan that includes more protein and calories.

Many older people with orthostatic hypotension (a sharp drop in blood pressure upon standing) have no related symptoms such as dizziness or lightheadedness. But they may face an elevated risk of unexplained falls.

There’s no evidence that maintaining a healthy lifestyle will suddenly boost the immune system. However, it’s clear that healthy lifestyle habits contribute to overall health, supporting the body’s ability to fight infections instead of creating new problems. Healthy habits that help maintain a robust immune system include getting seven to nine hours of sleep per night, exercising, reducing stress, eating a healthy diet, not smoking, drinking alcohol only in moderation, maintaining a healthy weight, and getting underlying conditions under control.
