Leg strength becomes even more vital as people age, as the legs are essential for routine movements such as going up and down stairs, sitting and rising from chairs, bending over and standing up, and protecting against falls. The main leg muscles are gluteals, quadriceps, hamstrings, and calves. Some exercises that can help strengthen these muscles are bridges, step-ups, and heel raises.

According to a 2025 study, women who walked at least 4,000 steps per day once or twice a week had a lower risk of cardiovascular disease and early death compared with women who did not reach this threshold.

A form of strength training called time under tension (TUT)focuses on the amount of time muscles are activated during an exercise rather than the number of repetitions or amount of weight. TUT forces people to use a slower tempo and controlled movements when exercising, which keeps the muscles engaged longer, helping to stimulate muscle growth. TUT can be applied to practically any type of strength training exercise, including free weights and gym machines.

Research suggests that people can exercise in the evening without it affecting their sleep if they avoid physical activity several hours before bedtime.

Ellipticals are stationary exercise machines that simulate walking, running, or stair climbing. They combine cardio with strength training and can simultaneously engage the upper and lower body for a full-body workout. Ellipticals also offer a low-impact exercise, placing less stress on the knee, hip, and ankle joints, which make them ideal for people who have knee or hip osteoarthritis or are recovering from an injury.

There are many ways people can meet the national guidelines for weekly activity. While running and walking are popular exercise choices, they are not the only options. Many sports and activities provide a similar heart-pumping workout, such as boxing, swimming, cycling, basketball, dancing, and even pickleball. People can also get creative and do circuit training using gym machines or perform cardio exercises at home.

Exercise is one of the most powerful tools for preventing heart disease and extending life. Physical activity triggers favorable changes such as making cells more sensitive to insulin and reducing inflammation. It also helps keep blood vessels supple and flexible (which supports efficient blood flow), strengthens muscles (which helps burn more calories), and remodels the heart, making it more efficient at pumping blood through the body. Together, these changes all reduce a person's chances of developing common risk factors for heart disease, including diabetes, high blood pressure, high cholesterol, and obesity.

Walking is often viewed as a casual form of exercise, but it also can be your primary form of moderate-intensity exercise if you increase the intensity, duration, and frequency of your workouts. You can adopt several types of workouts to help increase pace and endurance, such as intervals, timed walks, and pole walking. Wearing appropriate walking shoes and improving their walking mechanics also can improve walking speed and endurance.

A 2025 study found that many people who use a fitness app to track their daily steps were able to maintain or increase their numbers over two years, suggesting the devices may have a long-term effect on motivation.

Diastasis recti occurs when the rectus abdominis muscle - the "six-pack" - separates and leads to a midline abdominal bulge. This might happen because of pregnancy, aging, genetics, excessive abdominal pressure, or abdominal surgery. The bulge becomes more noticeable when lifting heavy objects, getting out of bed, or even performing everyday tasks. The condition usually doesn't resolve on its own. Working with a physical therapist can help decrease the muscle separation.
