What could you do today to feel happier? Three strategies drawn from positive psychology, a field that aims to improve moods and lives, may help.

Older adults need a strong core to stay active and healthy. While the core comprises many muscles, the four main ones lie within the abdomen: the rectus abdominis in the front; the external and internal obliques on the sides; and the deep, flat transversus abdominis wrapping your midsection. Several core exercises work many of these muscles, but the dead bug exercise can engage all of them and is safe for older adults, as it can be modified for any age or limitations. The dead bug is done by lying on the back and moving the limbs up and down to imitate a dying insect.

A 2026 study suggested that women who consistently stay active throughout middle age have a significantly lower risk of dying early than peers who are inactive.

Harvard fitness expert Michele Stanten takes you through a simple exercise to tighten your abs, strengthen your back, and improve your balance.

Sleeping 11 additional minutes, doing an extra five minutes of moderate-to-vigorous physical activity, and eating just a quarter-cup more of vegetables each day was linked to a 10% reduction in heart attacks, strokes, and other serious heart problems, according to a 2026 study.

People who maintain or improve their heart-related risks over time are less likely to develop calcification of the aortic valve, which may lead to aortic stenosis.

People with higher levels of cardiorespiratory fitness were less likely to develop depression and dementia than those with low levels of cardiorespiratory fitness, according to a 2026 research review.

Men may be less flexible than women, but stretching offers important benefits for everyone, especially as they age. Stretching may help keep muscles limber, improve balance and posture, prevent injuries, and even benefit sports performance.

Around age 40, most people lose some height, and the decline accelerates with age. This "shrinkage" can be slowed by preventing osteoporosis and improving posture. Getting enough calcium and vitamin D can help increase bone density, and exercises for the back and abdominal muscles can help with posture.

Regular resistance training, with either home-based or gym exercises, improves strength, muscle size, power, endurance, and daily function. New guidelines recommend resistance training with high effort that works all major muscle groups at least twice a week.
